1. Presentation of the system
The C7000 control system offers a maximum of operating safety for industrial applications combined with two
versions for the operator interface. The C7000IOC takes
charge of the control in itself and the optional C7000
Advanced serves as a comfortable operator interface.
Distributed intelligence in networking cells represents the
most reliable system whenever operating safety is the
target. This is exactly how the Stulz C7000 control system
works, each A/C unit possesses its own controller while
all controllers can be linked together in a bus system.
This way a natural redundancy is obtained which assures the system functions with the least expense. And
we locate the intelligence there where it is needed, in
the A/C unit without long cables which could mess up
the signals.
Whereas the C7000 Advanced provides the well known
operating comfort - as did already the C6000 - the
C7000IOC can bring to bear his advantages when it
comes to modifications in the configuration of a large
air conditioning system with several units.
The idea of the second interface was to use a device
which is present everywhere, a computer. Using the
screen of a Laptop or PC provides the best way of visualizing parameter settings. This is the most comfortable
way of doing a component-related configuration.
intelligent management of high/low pressure-alarms, a
proportional fan speed control which opens a wide spectrum of applications and time-based functions like:
- week timer
- unit sequencing within definable unit groups
The heart of the C7000 control system is the C7000 I/O
controller on which up to 4 EAIO/EDIO boards for additional in- and outputs can be perpendicularly plugged.
The exploitation of the third dimension provides maximum accessibility and an easy board exchange in case
of modifications.
The C7000 control systems manages 3 busses:
1. IIC-bus for the communication between the C7000
I/O controller and the EAIO/EDIO boards
2. RS485 IO-bus for the communication among the
A/C units
3. RS485 BMS-bus for the communication with a
building management system
For service purposes like software download and control
via laptop a RS232 interface is located on the I/O controller the same as on the C7000 Advanced.
Beyond the basic air conditioning functions, the C7000
control system provides some interesting features like an

The EAIO-board is an extension board for analogous
inputs and outputs. It can be plugged on the I/O
controller board at each of the 4 sockets and will be
recognized by the IOC due to a self test.
There are several jumpers on board - 5 for each
input - which serve to adapt the board to different
sensor types.
How to use the Jumper setting table:
- choose the analogous input at which you have
connected a sensor.
- in the same line you can see the jumpers which
relate to this input.
- in the lower part of the table you can read in each
column the setting depending on the sensor type
you connected.
Example:
You have connected a 0-10V sensor at AIN 8.
The corresponding jumpers are 300-304. Jumper
301,303,304 must be set on position 1-2, Jumper
302 on 2-3 and Jumper 300 not at all.

2.7 Driver module
The driver module has the following features:
1. a static bus termination (120 Ohm), which can be activated by a jumper.
2. a circuit to set the bias for the bus. By means of two jumpers either a low bias (bus middle) or a high bias (bus
end) can be set.
3. protection against electrostatic discharge (ESD) impulses on the data lines
The interference immunity of the bus is increased by the driver module.
As far as the jumper settings are concerned, only the two settings shown below are allowed. The jumpers must be
changed blockwise. Other settings result in an unstable bus communication.
Participant at the end of the RS485 bus
This figure shows the jumper position for the participant at the end of the bus.
The rightmost jumper is located in a position where
the termination resistor is activated.
The other jumpers are set for a high bias.

3. Operator interface
3.1 Operational elements - C7000 IOC
The operational elements for the C7000 IOC i.e. the I/O
controller consist of the keyboard of your PC or laptop.
You operate the C7000 IOC by specified commands
which follow an easily comprehensible syntax.
To establish the connection from your PC to the C7000
you need a 9-line cable with SUB-D 9 connectors at both
ends (crossed type), which can be obtained as an option
and a terminal program e.g "C7000-Serice".
Connect the cable at a serial port of your PC and at the
service port X15 on the IOC.
when connecting the laptop to the IOC service port.
Start the terminal program.
If your PC is not equipped with a serial RS232 interface,
you may use a RS232-USB converter.
You can now communicate with the connected I/O controller (ioc), in return the IOC sends the following prompt
to your PC:
"ioc ##:>", where ## represents the bus address.
To prevent a destruction of electronical elements due to
potential differences, use a laptop with battery supply
The commands can be classified into three major categories:
1. bus specific control commands
2. commands related to A/C unit components
3. commands concerning the whole A/C unit
1. bus command
iobus
iobusok
2. component command

suctionv 1
gecwv
gvalve
drycool 1
pump 1
eheat 1
gasheat
pwwheat
humi 1
dehumi
fan 1
louver 1
Each command displays a detailed help for further parameters (if there are any) when it is followed by "h" like
e.g. "comp h".
A command of the second (component command) or
third category (A/C unit comm.) which is typed in without
any parameters displays all the information about its
subject (except "loaddefault ###" which is an execution
command).

ups
wprg

loaddefault dx1
The commands on a lightgrey (yellow) background need
no further parameters. The commands which are followed
by a number need this number because there are several
components of the same type.
The commands of the 2nd and 3rd category will be
largely explained in the context of the description of the
C7000 functions.
The iobus command edits the actually stored IO-busconfiguration.
This command is a control command and shows neither
help nor information but execute the command right after
pressing the return/enter-key.
General
The counting of any digital or analogous in- or output
begins with number 1. Despite this the digital/analogous
in- or output 0 can be assigned to any component. This
will allow the component to stay part of the configuration
even if it does not take part in the control.
A double assignment of inputs and outputs is technically
possible but only reasonable in exceptional cases.
Outputs in the languages English and German are available at the service interface.
If within a command, where the input of a number is
expected, nothing is entered, the terminal program interprets this as "0" (command "coolingprio" is interpreted
as "coolingprio 0").
Whenever a parameter is expressed by a logical function,
0 means no, disabled, 1 means yes, enabled.
If at unit start no valid configuration is found, a minimal
configuration for single refrigerant circuit-units is loaded.
Please note that no year date below 2000 can be entered.

This LED display flashes in the event of an alarm and remains lit after the reset key has
been pressed once.
This LED display lights up when at least one IOC within the bus is switched on.
The control of the selected A/C unit is switched on/off with this key.
The audible indicator issues an alarm tone when an alarm has occurred.
The display shows data, operating conditions and information for the operator's
guidance.
Operation - Navigation through the menus
The principal keys to navigate in and across the menus are the selector key
and the confirmation key, which have the function of the mouse for a PC.
The cursor, to keep the analogy with a PC, is represented by the inverse
display of a field content. This field may contain an expression, a number
or a symbol.
There are two types of menus: Selection menus and parameter menus. In
selection menus you can choose a menu point with the help of the selector
key and after having pressed the confirmation key it will bring you to the next
submenu. To get to the next menu on a level above there is a "Return"-field
in the top left corner of every menu.
In parameter menus, which represent the end of a menu branch, you can
select parameters with the selector key, but if you press the confirmation key,
the parameter is displayed black on a clear background with a black frame
and indicates this way the change mode. By the selector key you can change
the parameter value. Pressing the confirmation key finishes the modification
and displays the cursor inversely again.
In a few parameter menus, there is the comment "more" in the bottom frame line, which indicates that another window will be displayed after the last
parameter. You can also reach this window by typing the selector key "<"
when the cursor is on the field "return".
Note:
After the C7000AT has displayed a submenu of an IOC for 10 minutes without
key activation, it will show the main menu of the corresponding unit again.

Passwords
To access the Operate level and the Config
level a password is required.
There are 4 passwords in total, a user-specific
password for the Operate and Config level each
and a master password for each level.
The user-specific password can be modified
and is "0000" for both levels with the delivery.
The master passwords are reserved for service
staff and can not be modified.
Entering the password
The digits can be modified by the selector
key, after you have pressed the confirmation
key. After the digit adjustment confirm with the
confirmation key and pass over to the next digit
with the selector key ">".
When you have reached the last digit at the
right, you access the main menu of the Operate
resp. Config level by activating the selector key
">" (if the password was right).
There is no limitation for the number of
attempts.
The passwords for the "operate" and "config"
level are saved on the IOC board. So it is
possible for example to adjust the "operate"
password "1234" for an IOC with bus address
3 and the "operate" password "5678" for an
IOC with bus address 5.

5.3 Bus Layout
5.3.1 General
The IO bus consists of maximum 20 participants. In case of the C7000 system only C7000 IOC or C7000 AT bus
participants can be in the IO bus.
Each bus participant has its own IO bus address which must only appear once in the data bus.
The IO bus addresses range from 0 to 19.
The display of the C7000 AT shows the IO bus addresses in a bus overview (start window) as follows:
5.3.2 Configuration of the IO bus
The configuration of the bus is done automatically during start-up and operation. That means that all connected
bus participants log on automatically. The same applies in case of a failure - all bus participants are logged off
automatically.
Following preconditions must be fulfilled:
1. Each bus participant has its own bus address which must be unique in the bus system.
2. Bus addresses must range between 0 and 19.
3. All bus participants are connected appropriately with bus cables according to requirements (see next page).
4. The bus has to be terminated at the beginning and at the end.
Each bus participant saves the latest registered configuration during shut-down. Furthermore the bus participant
expects the same configuration after its next start-up.
In case new systems have logged on to the bus during the shut-down period, the bus participant detects these
systems and records them in the bus configuration without editing a message or an alarm.
In case a system has been disconnected from the bus which was active before shut-down, the bus participant
detects this condition and a bus error is triggered in the bus participant after the end of the alarm delay.
The same happens when a bus participant (IOC or C7000AT) is de-energized during operation.
All systems that are connected to the bus detect a bus error automatically. Accordingly this error is displayed on
the AT and IOC.
E/0409/57/27
5.3.3 Preparation before Installation
You need a shielded cable with two lines twisted and a cable impedance of 120 Ω (Recommendation Belden 9841), which you have to connect from unit to unit at the terminals
56-59 of each I/O controller (IOC). In the example below the bus termination of the two
units which form the end of the bus (IOC 01 and IOC 17) must be enabled.
The example of a RS485 bus shows a typical application with 7 IOCs and 1 C7000 AT.

5.3.4 Setting the Bus Address
The bus address is adjusted with the dip-switches on the IOC. The table at the right
shows the corresponding adjustment for all possible bus addresses. Please note that
the counting begins with 0 and ends with 19. A "1" means dip-switch in "ON"-position.
If you set an address higher than 19, this one is reduced to 19 by the software.
An IOC is delivered with the address 1 as standard, a C7000 AT has the address 0 as
standard.
On a C7000 AT the bus address is adjusted in the placement view.
Placement view
With the selector key you can shift the C7000 AT represented by
symbol "ME" to a new position and change its bus address this
way.
Left display: old position address 0, new position address 17.
To confirm the selection press the OK key.
Now the bus configuration must be confirmed to avoid the display
of a bus error, because a bus participant with the address 0 does
not exist anymore.
The addresses of all other participants are not affected by this.
in short:
1. connect units by bus lines
2. set bus terminations (beginning/end)
3. adjust bus-IDs
4. confirm bus configuration

When the availability of a configured unit is 0%, an error is
indicated.
The AT 19 detects, that the IOC 6 has been available in the bus, but can not be reached anymore. When the disconnected unit is switched on again, the bus error is automatically deleted at all bus participants. A bus error can
also be deleted by inputting the command "iobusok" at an IOC or an AT.
E/0409/57/29
There is another way to delete a bus error on the AT and to transfer
so the actual bus configuration.
For this purpose all systems have to be selected simultaneously
and afterwards the OK-button has to be pressed.
After entering the password (2718) the faulty unit (address 6) is
deleted from the bus. The bus error disappears.
5.3.6 Special cases
Disconnecting a bus
An important aspect concerning the display of the IO bus is that the display is always exclusively dependent on
the C7000AT which is in use at the moment.
For example a bus disconnection between the bus participants 4, 5, 6, 7, 16, 17 and the bus participants 18, 19
results in two completely independently running busses.
However the bus participants 4, 5, 6, 7, 16, 17 report the bus participants 18, 19 as faulty and vice versa.

ERROR IN THE BUS CONFIGURATION DETECTED.
The bus error has an adjustable alarm delay. Once this delay has expired the bus error is triggered. This delay is
separately adjustable for each bus participant.
Address conflict
The second failure concerning the bus is a conflict in the address. A conflict in the address occurs when two or
more bus participants have the same bus address.
That means that the two bus participants which have the same address send simultaneously data to the bus. This
on the other hand would destroy the data on the bus.
Communications via the bus would be limited.
But this does not happen because bus participants stop the data transfer immediately as soon as they detect that
another participant with the same address is sending a data package.
That means that they stop sending and hence do not participate in the communication on the bus anymore.
An address conflict is triggered immediately as soon as a unit has performed a deactivation.
In our example two ATs have the bus address 19.
As soon as the communication on the bus starts, one of them detects that the address 19 has been assigned
twice and performs a deactivation.
The result is that only one bus participant with the same address is active after a short time.
E/0409/57/31
The user is requested to choose another bus address at the C7000AT which has detected the address conflict.
For it the following positioning window is displayed.

BUS ADDRESS CONFLICT AT ADRESS ‚ME‘ = 19 DETECTED.
If an address conflict exists, this one
is indicated for the corresponding
bus participant.
The other AT with the bus address 19 continues operation without any interference.
After the bus address has been assigned properly the address conflict will be solved automatically.
An address conflict can only be displayed at the unit, which causes the address conflict, because it excludes itself
immediately from bus communication. If this unit is a C7000AT, this is displayed on the display. An address conflict
can only be displayed at unit "ME".
If the unit is a C7000IOC the error LED on the board flashes, the state of the bus configuration can then be requested by using the service port.

6.1.2 Overview structure
Due to the complexity of the menu ramification, it was impossible to display entire menu branches on one page.
We therefore applicated a city map screen on the menu
overview, consisting of columns and rows which serve to
easily relocate single submenus within the overview.
Each page features a capital letter and is subdivided in
three columns.
The Info menu runs from page A to E.
The Operate menu runs from page F to J.
The Config menu runs from page K to S.
The top row, in which the top menu (Info, Operate or
Config) is placed, has no line identification. The rows
below for the submenus are named from "a" to "f".
There are up to 4 submenu levels.The first two submenu
levels are horizontally located. The third submenu level
is vertically located. The fourth submenu level is marked
by a grey background.
On the pages which follow the overview, only the parameter menus are explained, these are normally the
menus of the lowest submenu level.

Values
Operate
The first item of the menu concerns the adjustment of temperature setpoints.The
following items serve to adjust the temperature limits, which are decisive for the
alarms "temperature/humidity too high/low".
Two temperature setpoints can be adjusted, setpoint 1 concerns the operation by
day, whereas setpoint 2 concerns operation at night according to the week timer
(page 78).
Following the limit values for the room air sensor. The "MIN" column contains the
values for the lower temperature limit and the "MAX" column relates to the upper
limits accordingly.
If e.g. the minimum room air temperature is passed under by the measured value,
the alarm "Room temperature too low" is displayed.
In the line below you can set the alarm delay in seconds.
The values for the supply air sensor can be adjusted in the same way.
F1d
You can set the same parameters for the air
humidity. However no difference between
day- and night setpoint is made.
Here you can input a setpoint for the raised
floor pressure. If this value is different from
zero, the raised floor pressure control will
begin. See chapter 7, special functions.
F2b
F1e
You can set alarm delays and limit values for
the water temperature. When the limit values
are exceeded, the alarms "Water temperature too low/high" are released.
For the operation of pump stations you can
set a pressure setpoint. The pressure setpoint represents the pressure increase by
the pumps.
When the C7000 is used to control a pump station, the water pressure is the only parameter which is controlled. This mode represents a special function of the C7000.
F3b
Here you can input a setpoint for the condensation pressure of the refrigerant. The
G valve is controlled according to this setpoint.
For the DX-mode and the mixmode in case of proportional GE control individual
values can be set. The setpoint for mixmode should be smaller than for DX mode
to discharge the compressor. This way free cooling by the water coil has a greater
part in total cooling.
For normal GE control only the DX value is operative.

Compressor sequencing in units with two refrigerant circuits:
The controller software tries to equilibrate the compressor runtimes. Once in an
hour the software checks whether the difference between the runtimes is 20 hours
or more.
If this is the case and if the compressor with the bigger runtime has a smaller start
value than the other compressor, the start values and hysteresises for summer and
winter operation are exchanged between the compressors.
General:
The bullet items within the text refer to the corresponding command at the bottom of the page.
In general the parameters which can be modified, are numbered line by line from top to bottom. If a line contains several

ECO Louver
Operate
This function enables a "Free cooling" with outside air, which is directed by a louver
system. Three louvers are necessary, which will be controlled in parallel by a single
analogous output.
- Fresh air louver for the inlet of fresh outside air
- Circulating air louver for the circulation of the room air
- Exhaust air louver for the outlet of warm room air
The fresh air and exhaust air louver are operated in parallel, the circulating air louver
is operated in a reverse sense to these louvers. The setting is done by determinating
the sense of rotation at the louver actuators.
Free cooling is enabled, when:
1. room humidity is within determined limits (see diagram) and
2. outside air is cold enough. This means when the temperature of outside air is
below the EcoCool start value ➊.
Free cooling is stopped, when the outside temperature is above the EcoCool start
temperature ➊ + hysteresis ➋ or when the room air humidity is outside the limits.
The start temperature ➌ for the control must be entered as a positive difference to the
air temperature setpoint. In the fourth line you can set the gradient ➍, which defines
the range, in which the fresh air and exhaust air louver opens from 0 to 100% and
the circulating air louver closes in the same way.
Additionally to normal operation there exist an emergency operation. If no compressor is in the condition to operate, the free cooling by EcoCool louvers is enabled
independently of the limits of air humidity and air temperature.

Only the first heating can be proportional. If this is the case and if there are several
heatings (up to 3), only the start value and the gradient of the first heating are decisive
for the control. Each time the proportional heating reaches 100% heating capacity
another reheat is added and the first heating is reset to 0%. This way up to three

Dehumidification (Part 2)
There four ways of realizing a dehumidification:
1. by reducing the fan speed and CW valve operation, this is
the only way of dehumidification for CW-units.
2. by shutting down a part of the evaporator via a solenoid
valve. (not for CyberAir 2 units)
3. by the electric expansion valve (only in CyberAir 2 units)
4. by reducing the fan speed and compressor operation.
The choice of the dehumidification type is made by the controller according to the following conditions: The priority lies on
reducing the fan speed. This is the case for ACW/GCW/GE-
GE/CWvalve or GE pump
configured ?
no
units in mixed operation. Only if the compressor is actually in
operation and if a dehumidification valve is present, the 2nd
way of dehumidification is chosen. The two dehumidifying ways
are never applicated simultaneously.
If no dehumidification valve is present as in units of the series
CyberAir 2, dehumidification is carried out by the electric expansion valve. If this is insufficient, the fan speed is reduced
additionally after a time delay.
The decision procedures of the controller are displayed in detail
in the scheme below.

With the room control with supply air

via a second T/H sensor in the supply
air. Primarily the control takes place as
for room air control, only if the measured
supply air temperature exceeds the start
temperature ➋ the temperature setpoint is
shifted. The extent of the setpoint increase
is determined by a factor which you enter,
as a gradient ➌, in the menu.
The relationship, according to which this
happens, is made clear by the graph
opposite. A steep gradient drastically
corrects the failure to meet the supply
air temperature, but has the risk that the
control circuit starts to oscillate.
With humidity control the setpoint shift
takes place in the opposite direction. If the
adjusted starting humidity ➍ is exceeded
by the measured supply air humidity, the
setpoint is reduced. You can also enter a
gradient factor ➎ for this. The relationship
is shown in the graph opposite.

The supply air control with room air limitation is based on the same control principle

The controller offers the possibility to have start a stand-by unit when an adjustable
positive temperature difference to the air temperature setpoint is achieved. This difference can be adjusted by the parameter "Overloadstart" ➌ . The adjustment 0.0K
disables this function.
When the temperature difference is obtained the A/C unit, so far as it is defined as
standby unit, will be started. The sequencing function is not influenced by this. In
order to use this function, a zone must be defined.
You can determine an integral factor ➍ for the air temperature control to avoid a control
discrepancy which is characteristic for P-controllers. In this case a variable setpoint
Svar, which is recalculated every 5 minutes is decisive for the control. This variable
setpoint is calculated by adding the setpoint alteration dS to the previous setpoint.
The values for the integral factor can be varied between 0 and 10%. A low value should
be used to start with in order to prevent the control system from oscillating. 2% are
recommended and can stepwise be increased to find out the limit of safe control.

In the second line you can adjust a unit start delay ➋. By different start delays for
different units it is avoided that the most current consuming components start simultaneously and overcharge the power supply of the building.
With the parameter in the third line you can effect a change-over of the two chilled
water valves in CW2 units. The parameter in the fourth line displays the state of
change-over. For details, see chapter 7 "Special functions, CW2 units".
The parameter "OTE" ➎ in the fifth line is customer specific, for standard units the
setting must be "STULZ". For enabling the OTE software this parameter is set to
"OTE".
With the parameter ➏ in the sixth line you can determine whether the unit may be
started by a remote on/off signal. (0 = no, 1 = yes, all other stop causes (Timer, BMS,
local stop, sequencing) are deleted. The remote on/off signal has the priority).

Cooling priority
Config
The cooling priority determines the overriding cooling circuit for units with
two different cooling systems (Dual-Fluid units). The parameters GE, CW
and DX can be adjusted.
GE - no priority, this is the adjustment for GE-systems, where a mixed
operation of both systems is possible.
CW - means, that chilled water cooling is prior at ACW/GCW-units.
DX - means, that compressor cooling is prior at ACW/GCW-units.
The diagram below displays the conditions for a malfunction change-over
at Dual-Fluid units.
For a better understanding:

The week timer is based upon two different temperature setpoints which you have
already adjusted in the menu F1c. Setpoint 1 is represented by a "1", setpoint 2 by
a "2".
The setting is user-friendly. Each digit represents an hour of the day. The weekdays
are displayed in lines. With the selector key you can jump between the hours of the
day. At the end of a line the cursor jumps to the beginning of the next line.
With the OK key you modify the value of the digit where the cursor is placed. Three
values are possible: 0, 1 and 2. By pressing the OK key these values appear in rising
order and will then begin at "0" again.
By pressing the key combination selector key + OK key the value, on which the
cursor is placed, will be copied to the next digit (corresponding to the selected direction
of the selector key). This way you can easily adjust several hours or days.
For each hour of each day of the week you choose among three settings:

In the first line you add the compressor to the configuration by entering "1". With "0"
you disable the compressor although all settings concerning the compressor are
kept. ➊
You can determine a digital output for the compressor on/off signal. ➋
In the third line you can:
- assign the digital input for the low pressure alarm ➌
- adjust, whether the low pressure alarm releases a common alarm (0= no, 1 = yes)
➌a
- adjust the alarm priority for the low pressure alarm ➌b
In the fourth line you can:
- assign the digital input for the compressor alarm ➍
- adjust, whether the compressor alarm releases a common alarm (0= no, 1 = yes)
➍a
- adjust the alarm priority for the compressor alarm ➍b
Setting the alarm priorities means assigning the corresponding alarm to an alarm
relay with the adjusted number.
The low pressure alarm can be managed in a way to avoid a premature and unnecessary service intervention.
If the LP switch releases, the compressor is stopped and restarted after the compressor pause has elapsed. The LP alarm is inhibited during the winter start delay.
This way the controller tries to bypass temporary LP alarms.
You can limit the number of compressor restarts in "RESTARTS" ➎ within a time
space you can adjust in the left column of the fifth line to avoid an LP alarm. You can
define the time space in the right column of the same line ➎b.
If after the maximum number of restarts, the LP switch still triggers, the LP alarm is
released and the compressor is definitely switched off. Using the optional LP-sensor
in addition you can adjust in the medium column of the same line a threshold ➎a
which marks the lower limit for the permissible pressure range.
With a HP sensor (either part of G-valve or separate option) high pressure alarms
can be equally managed for the same reasons as LP alarms.
You can limit the number of allowed compressor restarts in "RESTARTS" ➏ within a
time space you can adjust in the left column of the sixth line. You can define the time
space in the right column of the same line ➏b.
If the threshold ➏a of the HP within this time space is excessed at least the adjusted
number of times, the HP alarm is released and the measure which you have adjusted
in HP mode ➐ is taken.
0: HP alarm will be triggered

Following menu:
In the first line you can adjust a setpoint ➏ for the opening degree of the GE valve.
This parameter is relevant only for the proportional GE control. For this a separate
manual exists.
Additionally you can prevent mixed operation of Freecooling and compressor cooling
by setting the "Close at comp" value ➐ to "1". (see graphic below).
In the third line you can adjust, whether the valve shall close as soon as the water
temperature exceeds the air temperature setpoint ➑.
In the fourth line you can adjust, whether the valve shall be used for heating ➒. The
control characteristics will be changed by this setting. When the air temperature falls
the valve opens, a rising air temperature will close the valve gradually.
In the fifth line you can adjust, how the valve will be controlled ➓.
Setting 0: Valve closed at 0V at the output, valve open at 10V at the output.
Setting 1: Valve closed at 10V at the output, valve open at 0V at the output.
In the sixth line you can set a time delay which must pass until the control of the
GE/CW valve begins and the water limit alarms are monitored. Until this time has
elapsed, the valve is fully (100%) opened.
The parameter in the seventh line is only important for CW2 units.
Here you can set an opening degree for the CW valve of the first water circuit. This
opening degree is kept by the valve while the cooling is produced by water circuit
2. By this, a minimum water flow is guaranteed in circuit 1, which is necessary to
measure the water temperature. With a sufficiently low water temperature the cooling
production can be switched back to circuit 1. Without a cooling request in circuit 1
the valve is completely closed.

With the parameter "A-OUT" you adjust the analogous output of the proportional

The pre-start serves to provide a sufficient flow for the heat absorbing medium and
to pre-cool the heat absorbing medium. When compressor operation is requested,
the G-valve opens and the compressor start is delayed by the pre-start time. ➌
The pre-open value is the G-valve opening degree which should be obtained during
the pre-start time. ➍
To avoid a constant discrepancy from the set value there are three parameters, which
imitate the behaviour of an integral control.
The control factor ➐ is the decisive value, by which the extent of the control correction is adjusted in the way of calculating the actuating variable after the lapse of an
adjustable control cycle ➎ according to the following formula:
Snew = Sold - f • (set value - actual value)
S: actuating variable - here valve opening
f: control factor
Set value: condensation pressure setpoint
Actual value: condensation pressure actual value
To avoid a drastical change you can adjust a maximum control correction ➏. This
control correction relates to the old actuating variable in each cycle.
The setpoint for the valve opening is entered in the eighth line. ➑ This setpoint is
relevant for proportional GE control only. The proportional GE control is described
in a separate manual.
In the last line you can enter a value for the minimal opening ➒ of the G-valve. The

With the parameter "A-OUT" you adjust the analogous output of the proportional

The opening degree of the HGBP valve is controlled according to the air temperature. If the actual temperature is below the setpoint, the opening degree rises to the
adjustable maximum opening degree. If the actual temperature is above the setpoint,
the opening degree falls to the adjustable minimum opening degree.
A proportional factor ➍, an integral factor ➎ and a differential factor ➏ can be adjusted
for the precise control. In the third line you can adjust the control cycle ➌.
The pre-runtime serves to softstart the compressor. When compressor operation
is requested, the HGBP valve opens and the compressor start is delayed by the
pre-runtime. ➐
The pre-opening is the valve opening degree to which the valve is opened during
the pre-runtime. ➑
In the last line you can set a minimum and a maximum opening for the HGBP valve.
The minimum opening ➒a limits the cooling capacity. The maximum opening ➒b
avoids a 100% short circuit of the refrigerant flow in case of a fully opened HGBP
valve. The compressor would operate in short circuit and trigger an HP alarm.
In case of a dehumidification request the HGBP valve is instantly closed in order to
keep a 100% refrigerant mass flow available.
The maximum refrigerant mass flow is needed for the effect of passing under the dew
point by partial cut-off of the evaporator (CyberAir 1, Compact DX and Mini-Space)
but also for fan speed reduction and dehumidification by the EEV (CyberAir 2).

In the next line you determine the reheat type (2-point: reheat with on/off control,
Linear: reheat with proportional control). ➋
With the parameter "D-OUT" you determine a digital output ➌ for the electric reheat.
The proportional electric reheat is controlled by pulse width modulation and the
reheat receives the control signal by a fixed PWM output. A digital output has not
to be set for the proportional electric reheat.
Alarm treatment:
The digital input for the electric reheat alarm can be assigned by the "D-IN" parameter. ➍ You can adjust, if the e-heating alarm releases a common alarm (0= no,
1 = yes). ➎
Setting the priority for the heating alarm ➏ means assigning the corresponding
alarm to an alarm relay with the adjusted number.

The first three parameters are irrelevant for units of the CyberAir2 series. For these

By setting the parameter "VALVE" on 1 you add a dehumidification valve to the configuration. With "0" you disable the dehumidification valve. ➊
In the second line you can configure a hotgas bypass for the compressor by entering
a "1". ➋
When dehumidification with compressor operation is requested, the hotgas bypass
is closed, because the maximum refrigerant mass flow is needed for the effect of
passing under the dew point.
This is also valid for dehumidification by compressor operation with fan speed reduction.
With the parameter "D-OUT" you determine a digital output for the dehumidification
(solenoid valve for partial evaporator cut-off). ➌
To avoid a feedback circle of dehumidification and cooling, where the sinking temperature arouses an increased relative humidity which entails again a dehumidification
request, you can adjust a stop temperature ➍, which is entered as a negative difference to the air temperature setpoint and avoids dehumidification when it is passed
under.
With a fixed hysteresis of 1 Kelvin the dehumidification is switched on again, when
the room temperature rises again above the stop temperature.

In the next line you determine the fan type (2-point: fan with on/off control, Linear:
EC-fan with proportional speed control). ➋
With the parameter "D-OUT" ➌ you determine a digital output for an on/off fan.
In case of a proportionally controlled fan the enabling signal is available at this
output.
With the parameter "A-OUT" you adjust the analogous output of the proportional
signal for a speed controlled fan. ➍
The parameters:
- control cycle ➎
- max. control correction ➏
- control factor ➐
are only necessary for the proportional GE control, which is explained in a separate manual and for the raised floor pressure control. With these parameters the
characteristics of an integral control can be performed.
The offset is used to adapt the airflow to unexpected conditions on the site ( lower/
higher pressure loss).➑
The minimum speed, which you can adjust here, can only be bypassed by the
adjustment in "REDUCE SPEED".
For DX units ➒a and CW units ➒b (determination by cooling priority) separate
minimum speeds can be adjusted.
The maximum speed should be adjusted according to the required layout airflow.
For DX units and GE units the "max. DX" speed ➓a is valid, for CW units the "max.
CW" speed ➓b is valid. For Dual-Fluid units the speed selection depends on the
cooling priority. In case of a malfunction changeover the corresponding speed is

With the parameter "START 100%" ➊ you adjust a time which must elapse before
the fan control begins. This way an airflow alarm is avoided which could occur due
to the fan inertia. During this time the fan is operated with 100% speed.
By the "PRERUN" parameter ➋ you adjust the delay for the inhibited start of all
components, except the glycol pump, in relation to the control start with alarm
monitoring. By different pre-runtimes for different units it is avoided that the most
current consuming components start simultaneously and overcharge the power
supply of the building.
The fan over-run time ➌, which you can adjust, serves to reject hot or cold air in
the A/C unit and avoids an accumulation of heat at the reheat or of cold at the
evaporator.
If during a time which you adjust with "REDUCE TIME" ➍a no action (cooling, heating, humidification, dehumidification) has been taken, the fan speed is reduced
by the percentage which you adjust with "REDUCE SPEED" ➍b.
The "FILTER OFFSET" ➎ is entered as a positive difference to the maximum speed.
If a filter alarm is released, the maximum speed will be increased by the filter offset
in order to overcome the higher resistance of a clogged filter.
If during the time until the dehumidification reduction comes into effect ➏a a
dehumidification request exists, the dehumidification is carried out by fan speed
reduction. This time delay allows to control the humidity by a dehumidification by
the expansion valve in the meantime. For units without electrical expansion valve
this parameter should be set to "0".
The "DEHUM.SPEED" ➏b is entered as a negative difference in % to the maximum
speed. This is the fan speed for the first way of dehumidification.
The "UPS SPEED" ➐ is also entered as a negative difference in % to the maximum
speed. Receiving a UPS-signal the controller will apply this reduced speed for an
emergency operation.
If the A/C unit is operated during nominal operation with a low airflow, the fan speed
can be raised, when the temperature setpoint is exceeded. The fan speed increase
depends on the temperature difference to the setpoint.
For this you adjust a positive temperature difference ➑a to the setpoint, which
represents the start point of the speed increase.
Then you adjust a maximum speed ➑a for the overload operation and another
temperature difference ➒ to the setpoint,
which marks the end of the proportional
Fan speed
fan speed increase. Having attained the
second temperature difference, the fan
Setpoint
is operated with the maximum speed
for the overload operation.This speed is

kept even if the temperature continues
to rise.

With the parameter "PURPOSE" you specify for what the sensor is used ➌.
See left listing.
With the parameter "A-IN" you adjust the analogous input for the proportional

The following 5 items serve to calibrate the sensor. The minimum measure value
(phys. value) ➏a is assigned to the minimum output (value). ➎a
The maximum measure value (phys. value) ➏b is assigned to the maximum output
(value). ➎b
The unit of the adjusted measure value depends on the sensor purpose (1-23). The
unit of the adjusted output depends on the sensor type (current, voltage).
If there is more than one sensor with the same purpose, an average value is calculated. In the seventh line you can adjust a maximum difference to the average
value.➐ If the maximum difference is exceeded, the alarm "Sensor ## excess" is
released. For the evaluation of the sensor excess alarm at least three sensors with
the same purpose are needed.
PURPOSE:
1 - Room temperature
2 - Room humidity
3 - Supply temperature

You can adjust in the ninth line, whether the sensor failure alarm shall release a
common alarm ➒a. And you can assign the alarm to an alarm relay ➒b.
NOTE:
You need two water temperature sensors for:
1. GCW-units with dry coolers
Water temperature 1 is always the temperature for the CW-circuit.
Water temperature 2 is the cooling water temperature, by which the dry coolers
are controlled.
2. CW2-units
Water temperature 1 is always the temperature for the CW-valve which is active,
when no change-over has taken place (no voltage at DIN 3).
Water temperature 2 is the temperature for the second CW-valve, which is active
after a change-over.
Sensors of the purpose
- Condensation temp.,
- Evaporation temp.
- Evaporation pressure
are not used up to now.
For these sensors and for the sensor condensation pressure no average value is calculated, if several
sensors with the same purpose are
configured.

In detail you can adjust the digital output for the common alarm ➊ and for the wintermode ➋. The wintermode signal can be forwarded to a BMS system. The state of
the free cooling mode ➌ (free cooling exists also in mixmode and when the Ecocool
louver is opened) and of the local stop ➍ (Control switched off by start/stop key)
can be output on a digital output.

Aux. Ports/Value output
N2f, N3f
In this window you can output analogous values on analogous outputs so that they
can be used by a BMS.
First choose a number for the value output. This number only serves to indicate
the value.
Then a window will appear, in which you can adjust parameters for the value output.
In the first line you can activate the value output. You can do the settings in line 2 to
5 in advance and save them, without having the value output be come into effect.
Only if you set the parameter in the first line to "1", the value output begins. When
several sensors with the same purpose exist, the average value is calculated.
In line 2 you determine the sensor the value of which will be output. The sensor is
selected by the purpose ➊ (as listed on page 93). If you select a purpose for which
no sensor exists, the output value is 0V. In the third line you set the analogous
output ➋.
The parameters in line 4 and 5 serve to calibrate the output. If you have selected a
sensor with the purpose "supply air temperature" and set the value 5.0 for the "min"
parameter ➌ in line 4, you define the lower limit by this. At 5,0°C a voltage of 0V will
be output. At 4,0°C also 0V will be output. By the "max" parameter ➍ in line 5 you
define the upper limit, at which 10V will be output.

Manual Operation
Config
O3d
When manual operation is used the C7000 control is put out of force.
The manual operation menu consists of two columns of parameters which are
decisive for the operation.
In the first column (titled EN.) you enable the manual operation of the listed component by setting the parameter to "1". ➊
The second column (titled STATE) displays the actual state of the component.
After you have enabled the man. op. in the first column, you can switch on/off the
component itself. ➋
For proportionally controlled components you can enter a percentage in the second
column (titled VALUE) which corresponds to an opening degree for a valve or a
capacity for any other component.
Components which exist either with on/off control or with proportional control have
both columns (STATE and VALUE). But only the corresponding parameter comes
into effect.
Sensors and external alarms can be simulated by the manual operation for the
purpose of testing the controller function.
When the manual operation menu is left (e.g. when the menu "components" is reached again), the manual operation of each component is disabled and the controller
takes over the control again.
When the fan is switched off, any other component is electrically
blocked and can not be started.
If the unit is de-energized, all manual settings are reset.
However, the adjusted proportional values are kept.

Q1a
Zone
Config
You can find a detailed description of the zone control in chapter 7. Special Functions.
Here you can see an overview over the adjustable parameters. Zone parameters
must only be set at one unit of the zone. Unit parameters must be set individually
at each unit.
➊. Unit assignment (unit parameter)
A zone is defined by the assignment of units to this zone. Maximum 20 zones
can be defined with the adjustments from 1 to 20. Zone 0 means that the unit is
assigned to no zone. The assignment is made individually for each unit.
➋. Cycle time (zone parameter)
The cycletime determines the lapse of time after which a changeover will periodically take place. With the setting "0" the sequencing is disabled.
➌. Number of defective units (zone parameter)
The entry is optional. If the number, adjusted here, is reached, the emergency
operation will be put into force. With the setting "0" the emergency operation is
disabled.
➍. Emergency temperature (zone parameter)
This temperature is the new sepoint when emergency operation is enabled.
➎. CW standby management (zone parameter)
With the setting "1" the CW standby management is enabled.
➏. Sequencing Test (zone parameter)
With the setting "1" the sequencing test with the fixed cycletime of 5 minutes is
enabled.
➐. Average value determination (zone parameter)
With the setting "1" the calculation of average values is enabled.
➑. Average value determination including standby units (zone parameter)
With the setting "1" also sensors from units, which are in standby mode, are taken
into account for the calculation of average values.
➒. Maximum fan speed (zone parameter)
The adjusted speed is valid for each unit of the zone, if the standby management is
enabled and when all units are running. In case of failure of one unit the remaining
units increase their fan speed so that the total air volume flow is kept constant.

By setting one of the two following parameters or the parameters "water start
temperature or water hysteresis" different from zero the proportional GE control is
enabled.
➊. Start temperature (zone parameter)
Below the outside air temperature which is set as start temperature the operating
modes FC, EFC and MIX are enabled.
➋. Hysteresis (zone parameter)
With this hysteresis the operating modes FC, EFC and MIX are blocked. Only the
DX operating mode is enabled in this case.
Q2b - Q2e
➌. Standby units (unit parameter)
A zone, in which a sequencing shall be carried out, must contain at least one
standby unit. With the setting "1" the actual unit is defined as standby unit. This
setting defines the initial state of the sequencing and changes according to the
actual state of the sequencing.
➍. Valid alarms (zone parameter)
With the setting "1" the corresponding alarm is defined as a valid alarm for the zone,
which entails that the unit is de-energized and the unit is registered as defect.
➎. Water start temperature (zone parameter)
Below the water temperature which is set as water start temperature the operating
modes FC, EFC and MIX are enabled.
➏. Water hysteresis (zone parameter)
With this hysteresis the operating modes FC, EFC and MIX are blocked. Only the
DX operating mode is enabled in this case.

7. Special functions
7.1 Raised floor pressure control
N1c
The pre-condition for this control is that every A/C unit is equipped with a
pressure sensor.
The option for a raised floor pressure sensor provided by Stulz features a
pressure range of 0-100 Pa or 0-250 Pa which is adjustable by jumpers. The
output signal can be adjusted to 0-10 V or 4-20 mA. This sensor must be
calibrated in the menu N1c.
The raised floor pressure control is enabled by a value in menu F1e which
is different from zero.
The control tries to keep the adjusted setpoint for the surpressure in the raised
floor. The air temperature control is continued but the pressure control has
priority to the temperature control.
F1e
M3c
For this control a proportionally controlled fan with an analogous output has
to be configured (Setting: LINEAR).
The control begins after the lapse of the "START 100%" time and the prerun time (M3e) with the maximum speed (max. DX or max. CW according to
the adjusted cooling priority). An offset value, which serves to adapt the air
volume flow to local conditions will not be considered.
Maximum speed serves only as an initial value for the control which starts
now by measuring the difference to the air pressure setpoint and reduces the
fan speed in case of exceeding the setpoint and increases fan speed when
the setpoint is passed under.
By three parameters (cycle, maximum control modification and control factor)
the characteristics of an integral control are achieved.
The adjusted minimum speeds are not passed under during control.
All speed increases or reductions for the fan with the exception of "reduction
according to time" (parameter called REDUCE SPEED) are put out of force. If
during the time adjusted here none of the functions "cooling, heating, humidification, dehumidification" is requested, the speed is reduced by the percentage,
which you have adjusted in the 2nd column of "REDUCE SPEED".
M3e
After the unit stop the fan runs during an overrun time, which serves to reject
hot or cold air in the unit.
The menu items, which are irrelevant for the raised floor pressure control
have a grey backgroung.
E/0409/57/101
H3c
In the menus H3c and M3d you can configure the alarms "air flow alarm"
and "filter alarm" with all corresponding parameters.
In the menu A1e of the Info level you can read and compare the actual and
set value of the air pressure in the raised floor.
A1e
7.2 Changeover of the water circuits - CW2 units
In the menu L3c you can choose between two operating modes:
1. Changeover operation (Parameter "Mode" : Separate)
2. Additional operation (Parameter "Mode" : Addedt)
M3d
L3c
Changeover operation
For changeover operation only the parameter settings for CW valve 1 (menu
G3e) are relevant (start temperature and gradient). In case of a changeover
these settings are applied on the active valve. The passive valve is completely
closed if it treats of valve 2. If the passive valve is valve 1 in the first water
circuit, it will be closed to the "value at switching". So to speak the output
A-OUT for valve 01 is commuted on A-OUT for valve 02 (or A-OUT 02 on
A-OUT 01).
If one or several of the following conditions are met, the output is commuted
from A-OUT 01 to A-OUT 02:
1. A voltage is present at the digital input (menu L3c, parameter D-IN), which
was assigned to the GE/CW valve.
2. DP 1025 is written with value "1" by a BMS.
3. DP 1025 is written with value "1" by inputting "1" for the parameter "CW2changeover" in menu K2b.
4. Water temperature in circuit 1 is higher than parameter "GE-off" (menu
G3e).
5. Water temperature in circuit 1 is higher than the air temperature setpoint, in
case the parameter "Close, if water above SP" (menu L3c) has been set
"1".
If none of the above listed conditions is true, the output is switched back from
A-OUT 02 to A-OUT 01.
The changeover is displayed by the parameter "State" in the menu K2b of
the Config level and is output by a freely adjustable digital output (menu L3c,
parameter D-OUT).
If a dehumidification request exists, the active valve will be opened 100% to
provide maximum cooling capacity for dehumidification.
E/0409/57/102
G3e
K2b
Additional operation
During additional operation both CW valves can be open simultaneously. Start temperature 1 and gradient 1 apply
to CW valve 1, start temperature 2 and gradient 2 apply to CW valve 2 (menu G3e). A commutation is possible
also during additional operation. This is done by an exchange of start temperatures and gradients between both
valves.
If one or several of the following conditions are met, the parameters of both valves are exchanged:
1. A voltage is present at the digital input (menu L3c, parameter D-IN), which was assigned to the GE/CW valve.
2. DP 1025 is written with value "1" by a BMS.
3. DP 1025 is written with value "1" by inputting "1" for the parameter "CW2-changeover" in menu K2b.
4. Water temperature in circuit 1 is higher than parameter "GE-off" (menu G3e). Valve 1 will be closed to the "value
at switching" in this case.
5. Water temperature in circuit 1 is higher than the air temperature setpoint, in case the parameter "Close, if water
above SP" (menu L3c) has been set "1". Valve 1 will be closed to the "value at switching" in this case.
Attention: If condition 4 or 5 applies to valve 2, this valve is completely closed.
If none of the above listed conditions is true, the parameters of both valves are changed back.
The changeover is displayed by the parameter "State" in the menu K2b of the Config level and is output by a freely
adjustable digital output (menu L3c, parameter D-OUT).
If a dehumidification request and no condition for a parameter exchange exists, valve 1 is opened 100% to provide
maximum cooling capacity for dehumidification.
If a dehumidification request and a condition for a parameter exchange exist, valve 2 is opened 100%
E/0409/57/103
7.3 Zone control
The zone concept is based on the idea to obtain a homogeneous room
climate within a determined space by distributed generation of conditionned
air.
Within an IO bus up to 20 zones can be defined. A zone is defined if at least
one unit is assigned to this zone. The assignment of a unit to a zone is done
by setting a zone number in the main line of menu Q1a.
This assignment must be done individually for each unit (each IOC).
Q1a
Average value determination
A basic principle of the zone control is the calculation of average values
of the measured values. Within a zone only one room temperature exists
which is calculated as the average value of all connected room temperature
sensors.
The same applies for the room humidity, supply temperature, supply humidity, outside air temperature, water inlet temperature 1, water pressure and
raised floor pressure, if existant.
J1a
The determination of average values can be disabled by the parameter in
the sixth line of menu Q1a (0 = off, 1 = on). By the parameter in the seventh
line of the same menu you can set whether standby units shall take part in
the calculation of average values. (0 = no, 1 = yes).
However the set values can be individually adjusted for each unit. If at all
they should only slightly vary.
Q2a
Standby units
In the menus J1a and Q2a you can put the unit in standby by setting the
parameter in the third line "1".
The existence of standby units in a zone increase the airconditioning operating security and provides the possibility to replace defective units by
standby units.
Alarm changeover
In order to changeover units in the event of an alarm, you can define alarms
as valid by setting the corresponding parameter „1“ in the menus Q2b, Q2c,
Q2d and Q2e. If such an alarm (defined as valid) occurs, the defective unit
is switched off and the standby unit with the next higher bus address is
switched on. If another unit with a valid alarm occurs in the zone, the next
standby unit (if existant) is switched on.
Some alarms cause the cut-off of the defective unit or the deactivation of
functions even if the alarm has not been defined valid. (for details see chapter
8.1 alarm messages).
The alarm „unit not available“ can not be deleted from the alarm list. This
alarm is always part of the valid alarms and appears in case of a bus failure
or when the unit has been de-energized.

Q2d
Q2e
Emergency operation
With the parameter in the second line of menu Q1a you can enable an
emergency operation. If this parameter is set "0", emergency operation is
disabled. By this parameter you set the number of defective units which are
necessary to enable emergency operation.
Emergency operation means that each A/C unit of the IO bus applies the
zone-specific emergency temperature as new temperature set value. The
emergency temperature is set for each zone with the parameter in the third
line of menu Q1a.
Q1a
Function of standby units
Even if the failing unit capacity of one zone is completely equalled by the
start of standby units, the defective units are counted as lacking.
To start an emergency operation just when the 100% unit capacity (without
standby units) is not reached anymore, the adjusted number of defective
units should be higher than the number of a zone's standby units.
Additional capacity - Temperature
K1d
You can have started a standby unit if the air temperature setpoint is exceeded by the zone temperature (Average value or unit temperature, when
average value determination is disabled).
The excess of the setpoint can be adjusted by the parameter in the third line
of menu K1d in the shape of a temperature difference. Setting "0" disables
the additional capacity function.
When the temperature sinks again, the additional capacity unit is switched
off with a hysteresis of 1K.
Additional capacity - Humidity
You can have started a standby unit if the air humidity setpoint is passed
under by the zone humidity (Average value or unit humidity, when average
value determination is disabled).
The undercut of the setpoint can be adjusted by the parameter in the third
line of menu K1e in the shape of a humidity difference. Setting "0" disables
the additional capacity function.
When the humidity rises again, the additional capacity unit is switched off
with a hysteresis of 3% relative humidity.
K1e
Precondition:
The additional capacity unit must be set as standby unit and must be assigned to a zone. Moreover the corresponding parameter (temperature or
humidity) "Overload" must have a value different from zero.
E/0409/57/105
The zone control comprises three specific functions:
1. Sequencing,
2. CW Standby Management,
3. Zone for proportional GE control
Q1a
7.3.1 Sequencing
The sequencing provides a time dependent unit changeover. By the use
of standby units, a high operating reliability the same as an even unit exploitation is achieved.
By setting the cycle time (parameter in the first line of menu Q1a) you adjust the lapse of time, after which a changeover is done periodically. This
means that the standby status is changed over the units one by one. With
the setting 0 (hrs) no sequencing is made.
Failure dependent change-over
Zone 02
Setting the cycletime causes the sequencing start.
Enabling the test sequencing (parameter in the fifth line of menu Q1a)
with the fixed cycletime of 5 minutes helps you to check the sequencing
function.
All basic zone functions which
have been described on the previous pages are also available
when the sequencing is enabled.
a. Average value determination or
deactivation
b. Alarm changeover
c. Emergency operation
d. Additional capacity
The sequencing runs independently from an additional capacity
function and independently from
defective units.
Even a defective unit can be set
standby by the sequencing. Only
when the unit has to be switched
on due to the changeover, the
control detects that the unit is
defective and the unit remains
switched off. Then the standby unit
with the next higher bus address
is switched on.
The unit, which is provided as
additional capacity, can only be
switched on during the cycles, in
which it is in standby.

7.3.2 CW Standby Management
Q1a
The CW standby management can be carried out with CW units and Dualfluid units with CW cooling priority. The basic idea is to share the heat load
permanently with as many as possible units in order to reduce the fan speed
of all units and thus to save energy. For this the provided standby units must
constantly take part in the cooling process. The total airflow is below the
airflow which is possible at most and is equalled in case of failure of one or
more units by increasing the fanspeed of the remaining units.
By "MAXFANSPEED" you adjust the fan speed which is to be kept in the
zone when all units are running. By "CW-ENERGY-SAVE" the CW-standby
management is enabled and in the same moment all standby units of the
zone are switched on. Both parameters are related to the zone and have
only to be adjusted at one unit of the zone.
The table beside displays how many units in a zone are necessary to keep
the total airflow at the indicated fan speed in the left column, when "f" units
have failed.
This correlation is represented by the following formula.
n>f•(

An A/C unit is switched off as defective unit if a valid alarm occurs at this
unit, in the same way as for the sequencing.
When a Dualfluid unit changes over to DX operation due to a fault like a "water
temperature too high" alarm , this unit applies the nMaxDX fan speed which
is higher than the MAXFANSPEED of the CW standby management.
The fan speed of the other units is not affected by this.
7.3.3 Zone for proportional GE control
Q2a
Such a zone consists of GE type A/C units, drycoolers and external glycol
pumps. Concerning the hardware, the zone exists in the shape of a common cooling water circuit and a common control of drycoolers and external
glycol pumps.
On the software level the zone operation is carried out by assigning the
A/C unit to the same zone and by setting the parameters "start temperature, hysteresis" or "water start temperature (=water inlet temperature 1),
hysteresis" different from "0". By this setting the proportional GE control is
activated. The zone parameters are transmitted to all units/controllers of the
zone and are assumed by these.
Some parameters as sequencing cycle and standby state are only operative
in DX mode. The proportional GE control is described in detail in a separate
manual.
E/0409/57/107
7.4 Free cooling with ECO-Cool Louver
L2b
This function enables a "Free cooling" with outside air, which is directed by a louver
system. Three louvers are necessary, which will be controlled in parallel by a single
analogous output.
1. Fresh air louver for the inlet of fresh outside air
2. Circulating air louver for the circulation of the room air
3. Exhaust air louver for the outlet of warm room air
The fresh air and exhaust air louver are operated in parallel, the circulating air louver
is operated in a reverse sense to these louvers. The setting is done by determinating
the sense of rotation at the louver actuators.
G2b
Configuration
By setting the parameter "ACTIVE" on 1 you add an ECO louver to the configuration.
With "0" you disable the ECO-louver.
With the parameter "A-OUT" you determine a analogous output for the louver.
Control
Free cooling is enabled, when:
- room humidity is within determined limits (see diagram) and
- outside air is cold enough. This means when the temperature of outside air is below
the EcoCool start value ➊.
Free cooling is stopped, when the outside temperature is above the EcoCool start
temperature ➊ + hysteresis ➋ or when the room air humidity is outside the limits.
The start temperature ➌ for the control must be entered as a positive difference to the
air temperature setpoint. In the fourth line you can set the gradient ➍, which defines
the range, in which the fresh air and exhaust air louver opens from 0 to 100% and
the circulating air louver closes in the same way.

7.5 Pump station control
The concept of pump station control is based upon the idea that one pump station
provides the water conveyance for up to five units, which need water for cooling.
S1b
Due to the differing need of cooling water the water pressure in the system is exposed
to big variations. This control assures that the water pressure at the unit outlet is kept
constant by pump speed control.
The pump station control represents a special control in the C7000 and can be set
in menu S1b by the pre-configuration "PS". The corresponding command via the
IOC service port is:
PS
"loaddefault ps"
If the pump station is equipped with a C7000AT, the actual value of the water pressure at the unit outlet and optionally the water temperature is displayed in the main
menu of this controller.
In the bus overview the pump station is displayed by a symbol, which contains the
values of these two parameters.
The units, which are provided with water and the pump station itself form a zone,
which must be defined at the controller of the pump station.
Temperature
Pressure
Attention:
The pump station zone represents a special zone which must not be confused with
the zone operation, which you can set in menu Q1a.
This means, that an A/C unit can belong to a pump station zone and can be part of
another (sequencing) zone simultaneously.
The single units must be assigned to this zone at the pump station controller by means
of their bus addresses. At the C7000AT you can do this by setting the parameters
for the units "1“. In menu K2d of the Config level the possible units of the IO-bus are
displayed in four lines. The units with the bus addresses from 0 to 4 are displayed
in the first line by placeholders "-0-“. The other units are displayed in the following
three lines corrspondingly. By setting the parameter "0“, the corresponding controller
is taken out of the pump station zone.
K2d
Assigning units to a pump station zone is done in the C7000IOC of the pump station
by the command:
pszone + 3
By the following command the unit with the address 3 is taken out of the pump
station zone.
pszone - 3
When a unit sends a cooling water request on the IO bus, the pump station controller
verifies whether this unit is part of its pump station zone and starts pump operation
if the result is positive.
Cut off by error:
In case of an alarm of the flow monitor or a failure of all configured pumps the pump
station is switched off.
With the application of a pump station you do not have to configure pumps in the
GE units.
E/0409/57/109
Operate level
F2b
Values
For the operation of pump stations you can set a pressure setpoint. The pressure
setpoint represents the pressure increase by the pumps.
When the C7000 is used to control a pump station, the water pressure is the only

By setting the parameter "ACTIVE" on 1 you add a pump to the configuration. With
"0" you disable the pump. ➊
In the next line you determine which type the pump shall belong to (PS=pump
station pump). ➋
With the parameter "D-OUT" you determine a digital output ➌ for the pump enabling
signal.
With the parameter "A-OUT" you adjust the analogous output of the proportional
signal for the pump. ➍
The digital input for the pump alarm can be assigned by the "D-IN" parameter. ➎
You can adjust, whether the pump alarm releases a common alarm (0= no, 1 = yes).
➏
Setting the priority for the pump alarm ➐ means assigning the corresponding alarm
to an alarm relay with the adjusted number.
Each pump station contains two pumps. In normal operation both pumps run at low
speed. In case of a pump failure the speed of the remaining trouble-free pump is
increased.
However, you can adjust a standby operation.
Standby operation can be enabled in the shape of a sequencing based on time and
failure. With "partner pump" ➑ you select the number of the 2nd pump (0-4). Setting
"0" disables the pump sequencing.
The sequencing is based on a runtime evaluation. In case of a runtime difference of
more than 20 hours the pump with the shorter runtime is put into operation.
Following menu:
The first two parameters are not relevant for pump station control.
With the control factor ➌ you set the proportional factor.
In order to avoid a remaining control discrepancy and to correct a drastic change of
water pressure, an integral factor ➍ and a differential factor ➎ can be adjusted.
You can set the control cycle ➏ by the parameter in the sixth line. With the control
cycle you adjust the control speed.
By the parameter in the last line you can set a minimum speed ➑ for pumps.

By setting the parameter "ACTIVE" on 1 you add a sensor to the configuration.
With "0" you disable the sensor. ➊
In the next line you determine the sensor type (current, voltage). ➋
With the parameter "PURPOSE" you specify for what the sensor is used ➌.
See left listing.
With the parameter "A-IN" you adjust the analogous input for the proportional
sensor signal. ➍
The following 5 items serve to calibrate the sensor. The minimum measure value
(phys. value) ➏a is assigned to the minimum output (value). ➎a
The maximum measure value (phys. value) ➏b is assigned to the maximum output
(value). ➎b
The unit of the adjusted measure value depends on the sensor purpose (1-23). The
unit of the adjusted output depends on the sensor type (current, voltage).
If there is more than one sensor with the same purpose, an average value is calculated. In the seventh line you can adjust a maximum difference to the average
value.➐ If the maximum difference is exceeded, the alarm "Sensor ## excess" is
released. For the evaluation of the sensor excess alarm at least three sensors with
the same purpose are needed.
PURPOSE:
21 - Water pressure
optionally:
5 - Water temperature
You can adjust in the eighth line, whether the sensor limit alarm shall release a
common alarm ➑a. And you can assign the alarms to an alarm relay ➑b here.
You can adjust in the ninth line, whether the sensor failure alarm shall release a
common alarm ➒a. And you can assign the alarm to an alarm relay ➒b.

GE-mode
The outside temperature ➊ for the commutation from summer to winter operation is
decisive for the drycooler and compressor control. With this hysteresis ➋ the winter
operation changes to summer operation.
The winter operation is also switched over to summer operation, if an outside temp.
sensor breakdown is detected. An alarm "Outside temperature sensor defect" is
not displayed.
If no outside temperature sensor is configured, summer operation is active.

Notes:
- For all unit versions except CW and CW2 of the series CyberAir 2 the
dehumidification valve must be deconfigured and the electronic expansion
valve configured.
- Settings "ge21" and "ge22" are only appropriate for GE units of the series
CyberAir 1 (green column in the table).
- Using setting "ps" sensor 5 must be deconfigured. If the water outlet temperature shall be measured, a sensor must be configured for this.

9. Alarm treatment
9.1 Alarm display
C7000 AT
The alarm messages are displayed in the standard window of each unit with
IOC. At the same time the symbol
in the left bottom indicates that an
alarm has occurred.
An alarm tone proves the presence of an alarm independantly of the actual
menu window of the C7000AT.
Attention: The alarm tone can be disabled. (See page 22)

10. Configuration notes
First steps after the reception of a new software
1. Load software on IOC, resp. on C7000AT. (see 10.1 Loading a new software)
2. Check bus configuration (configuration is kept after loading the software)
3. Load a default configuration according to the unit type (see 8.1 pre-configurations)
4. Check the equipment by command "equip".
5. Configure additional components.
At the C7000AT you can do this in the Config-level in the submenus of the menu point "Components". Part of
the configuration is the activation of the component, the allocation of an output for the component control and
eventually the assignment of an alarm input.

10.1 Loading a new Software
For a C7000-control system there are two different softwares. The essential control software, which contains the
commands for the command level, is located in the FlashEPROM on the IOC-board. The second software contains
the menu structure of the C7000AT and is located in the
EPROM of the C7000AT board.
The control parameters in the IOC are resistent and do not
have to be re-entered after loading the software. This is also
the case for the IO bus configuration of the C7000AT.
For loading a software in the flash-EPROM of the IOC
you must connect the service port of the IOC to a serial
interface of your PC/Laptop by means of a RS232 modem
connection.
Switch off the master switch. Set the jumper JP7 to position
2-3. The master switch must then be switched on again.
The IOC is now in the „download“-mode. Start the program
"C7000-Service.exe" on your PC. This program can be
downloaded from the Stulz-website.
After the new software has been loaded, the master switch
must be switched off and the jumper JP7 must be set in the
position 1-2. After this switch on the master switch.
For loading a software in the flash-EPROM of the C7000AT
you must connect the service port of the C7000AT to a serial
interface of your PC/Laptop by means of a RS232 modem
connection.
Switch off the master switch. After this the jumper X6 must
be set in the position A. The master switch must then be
switched on again. The C7000AT is now in the „download“mode. Start the program "C7000-Service.exe" on your PC.
After the new software has been loaded, switch off the master switch and set the jumper X6 in position B. After this the
master switch must be on again. When switching on, ensure
that the new version number is correctly displayed.

Only for the C7000 AT:
In the next step all parameters, if they deviate from the default settings and the bus configuration, must be readjusted.
The default language is English. If you require another language, you can change this in the „System\Languages“
menu.

10.1.1 Operation of the program "C7000-Service.exe"
With an up-to-date WinXP/Vista system the program must only be copied onto the computer hard disk and can
directly be started by a doubleclick. The files (C7000-Service.exe and IOC-Service.exe) must be stored in the same
folder. With former WinXP versions, Win2000, WinME and Win98 the install-package which can be obtained from
the e-Stulz domain must be carried out.
Start C7000-Service.exe und click on the button "Terminal",
which starts the program IOC-Service.exe.
Select an interface to the PC (COM 1 - 9) and check the connection to the IOC or C7000AT by pressing the Return key. If
you receive a response from the IOC/C7000AT the connection
is established.
Clicking on the "Download" button opens a window, in which
you can enter the file which shall be loaded. This is done by
clicking on the button "Select file", which opens a dialogue
windows for the selection of a file. The file is a hexadecimal
file with the extension *.h86.
The file name gives information about the software destination.
C7000AT-Vxxx.H86 is destined for the C7000AT. C7000IOCVxxx.h86 correspondingly for the IO-controller. The number
behind the V indicates the version.
Concerning the block size and the transmission rate, you can
take the preadjusted values (1024 Bytes and 38400 kBit/s).
The transmission will then take approx. 2 minutes for each
software. With a longer cable however, you may be obliged to
reduce the rate.
E/0409/57/132
You can start the download now with the button "Start". The
single steps are indicated in the "Help/State" line, the progress
of each step in the "Download Progress" line.
Clicking on "Close" closes the download window. Pressing the
"End" button quits the program IOC-Service.
