WATER CONNECTIONS
GENERAL
CONNECTIONS SUPPORTS
The weight of the hydraulic connections must be supported
in the exterior of the unit so as not to stress the connections
of user devices (exchangers, coils, humidifiers, etc ) .
Piping must be designed with the least possible number of
bends and head variations. If the pressure chute of the
installation is above the useful prevalence of the pump, the
water delivery capacity is reduced as well as, as a
consequence, the thermal exchange and the yield.
ANTI-VIBRATION DEVICES
In case of units with anti-vibration devices, it is necessary to
assemble elastic joints, even on water connections.
INTERCEPTING VALVES
Install on the input and output of the user parts
(exchangers, coils, humidifiers, etc) So that it will be
possible to carry out all the service operations and possible
substitutions without emptying the installation.
RISK OF FREEZE
If the unit and the relevant water connections are subject to
temperatures near 0°C:
PRESSURE AND TEMPERATURE INDICATOR
Install on the input and output of the user parts
(exchangers, coils, humidifiers, etc) So that it will be
possible to carry out all the service operations.
AUTOMATIC OR MANUAL ESCAPE VALVES
Install the highest points of tubes in a way that the air can
escape form the circuit.
BLEEDING COCK
Install them at the lowest points of the circuit, so as to allow
emptying.
•
mix the water of the system with glycol
•
protect the tubes with heating cables under the tubes
insulation
•
empty the system by verifying that:
o
no taps are closed so they can not trap the water,
even after emptying
o
there are no low points where the water can
stagnate even after emptying; blow if necessary
INSTALLATION EMPTYING
The refilling of the water present in the installation increase
the oxidation phenomena and lime deposits.
LEAKAGE TESTS
Before performing the insulation of the tubes, carry out a
leakage test.
If necessary empty only the interested system section and
anyway empty or refill the installation if necessary .
TUBE INSULATION
All tubes of water must be insulated so that to avoid the
formation of condensation and thermal dispersions along
the tubes themselves. Verify that the insulation is the
vapour coil type. The connections for the air escape and for
the emptying must be out of the insulating thickness to
assure the accessibility.
EXPANSION TANK
The installation must be kept at the right pressure by both
an expansion tank and a combined valve of pressure
reduction and discharge; if the components are present on
the unit, they must be installed on the installation. The
expansion tank must be dimensioned in function of the
water in the installation.
CONDENSATE DISCHARGE CONNECTION
POSITION THE DISCHARGE PIPE SO THAT THE UNIT
DISCHARGE CONNECTION IS NOT MECHANICALLY
STRESSED.
M22740C6-04
Connect the condensate discharge pipe to the discharge tray
paying attention not to damage it.
Make a trap that, eliminating the depression caused by the
fan, stops the return of gas from the discharge pipe (see the
figure)
Connect the condensate discharge to a rainwater drain. Do
NOT use sewerage drains, so as to avoid the return of odours
if the water contained in the trap evaporates.
Finally, check that the condensate will drain correctly by
pouring water into the tray stud.

AIR CONNECTIONS
Proper execution and sizing of air connections are essential
for ensuring correct operation of the unit and an acceptable
level of silence in the room.
When designing and creating ducts, consider PRESSURE
DROPS, FLOW RATE and AIR SPEED which need to be
compatible with the characteristics of the unit. Special
consideration needs to be made for pressure drops that are
greater than the unit's static pressure, which would lead to
a reduction in flow rate resulting in unit shutdown.
the weight of the ducts must not be supported by the
connection flanges
place anti-vibration joints between the ducts and the
unit
the connection to the flanges and between the various
sections of the ducts must ensure an airtight seal,
preventing leakage in delivery and return which would
compromise overall system efficiency.
for units installed outdoors, the connection to the
flanges and between the various duct sections must be
watertight
limit pressure drops by optimizing the path, the type
and number of curves and the branches
use curves with a wide radius. Consider whether it
might be useful to equip them with deflectors
(especially if the air speed is high or if curves are tight)
FEATURES FOR DUCTS FOR TREATED AIR
1.
The inner surface of the duct must be smooth and
washable. It must not contaminate the air.
2. Thermally insulate the ducts and the flanges so as to
prevent loss of energy and condensation build-up.
3. Soundproof duct sections that are outside the building
in order to keep noise out of the ducts (from the
systems, from road traffic, aircraft, etc.)
4. Before entering the building, the ducts must have at
least two curves, with a wide radius and equipped with
deflectors, to favour noise absorption by the ducts.
Proper distribution of air in the room is essential for
ensuring comfort levels.
In the selection and positioning of grilles, outlets and
diffusers, the following are to be avoided:
5. excessive air speed
6. formation of stagnant zones and layering
7. entry of cold air into the room
8. formation of localized currents (due to uneven air
distribution)
9.
excessive variations in ambient temperature in the
vertical and horizontal planes
10. short circuiting of delivery air towards return air
For purposes of comfort, the following things need to be
considered:
11. air diffusers must be selected by checking the sound
power generated at nominal flow rate conditions
12. the disconnections to the diffusers are to be made
using flexible elements
13. the return grilles must be amply sized
For applications that require a high degree of silence in the
system:
14. In delivery and return, provide septum silencers,
preferably inserted in sections of ducts located outside
the building. The septums must ensure the required
dampening with minimum pressure drops (ONLY
OUTDOOR UNITS – do not print note).
15. Equip all curves with deflectors.
ACCESSORIES
The units can be supplied with the following accessories
(on demand) :
1) Mixing box
2) Hot water heating coil
3) Electric heating element
4) Spigotted discharge plenum
(for sizes 41-51-71, 4 spigots are provided instead of 3)
5) Filter section
All these accessories can be used alone or in the various
combination desired. They are easily assembled thanks to the
predrilled 25mm coupling flanges. The sequence illustrated below is
purely indicative.

RS485 SERIAL PORT
If Clivet provides only the units with BMS communication port (installed or provided separately), it is responsible only for
the units themselves and not for the units downstream. Therefore CLIVET is not responsible for operations such as
choice and installation of cables, connection, serial addressing and checks on network functionality.
On request, Clivet provides the specifications for the communication protocol of its units and the necessary guidelines to
connect them to RS485.
The card for RS485 serial line must be connected to the main card using the appropriate wire provided.
The network termination jumper alongside the screw terminal board for the connection of 485 must be inserted if the unit
is the last one in the network.

START-UP
ALL THE EQUIPMENT MUST BE COMMISSIONED BY AUTHORISED SERVICE CENTRES.
THIS SERVICE IS LIMITED TO START-UP OF THE UNIT ONLY AND NOT THE CONNECTIONS OR INSTALLATION OF
THE SYSTEM.
ONLY QUALIFIED TECHNICIANS MUST PERFORM THE FOLLOWING OPERATIONS.
Perform a seal check at max. working pressure checking
that no leaks are present.
PRELIMINARY CHECKS
Before checking, please verify the following
1.
2.
3.
4.
5.
6.
7.
the unit should be installed properly and in conformity
with this manual.
the electrical power supply line should be sectioned at
the beginning.
the sectioning device is locked and the proper warning
“not to operate” sign is placed on the handle.
make sure no tension is present
the coils must be clean and free of obstacles
the ventilators must be free of leaves, cardboard, fixed
obstacles (beams, barriers, etc.), snow, etc
the external ventilators must not be blocked
The external ventilators can be subject to a temporary
block, especially if the inactivity period before the first
start-up was quite long or if outside temperature is very
low. It is also possible to unblock them manually
(ONLY WHEN THE UNIT IS UNPLUGGED – RISK
OF INJURES) so that jams or electric overloads are
avoided when the unit is restarted.
AERAULIC SYSTEM
Check that:
1. the air filters are not removed from unit and are
cleaned (possible ventilation checks and the operating
starting period determinate a ducting “cleaning” with
conseguent filter precocius clogging, filters that must
be cleaned and replaced)
2. ducting are completed, connected and without
obstructions
3. possible dampers are opened (for ex. fire stop
dampers) and calibrated (for ex. fresh air damper,
control damper, ejection damper)
4. Grilles, outlets, and diffusers must be free of
obstructions (furniture, shelves, etc.), open and precalibrated, so as to ensure proper air distribution,
which is essential to comfort in the room.
WATER SYSTEM
Ensure that the plumbing system has been washed. Drain
the wash water before connecting the unit to the system.
Check that the water circuit has been filled and
pressurised.
M22740C6-04
01/10/07
Check that the shut-off valves in the circuit are in the
"OPEN" position.
Check that there is no air in the circuit. If required, bleed it
using the vent valves in the system.
Check that there are no ARIES EFFECTS in the transient
(pump and / or valve activation/deactivation)
When using antifreeze solutions, make sure the glycol
percentage is suitable for the type of use envisaged.

Check that the circulator pumps are not blocked. In fact,
their motor shaft may seize up, especially after long
shutdowns. Unblocking can be accomplished with a
screwdriver using the purge hole.
ELECTRICAL SYSTEM
Check the proper tightening of the screws that fix the
conductors to the electrical components in the board
(during handling and transportation, the vibrations could
have loosened them).
Verify that the unit is connected to the ground plant.
Control that all panels and protection devices of the unit
are repositioned and blocked.
Charge the unit by closing the sectioning device, but leave
it on OFF.
Make sure that the tension and net frequency values are
within the limit of:
230 +/- 6% single phase unit; 400/3/50 +/- 6% three-phase
unit
Control the unbalancing of the phases: it must be lower than 2%
.
Example:
L1 - L2 = 388 V, L2 - L3 = 379 V, L3 - L1 = 377 V
average of the measured values = (388 + 379 + 377) / 3 =
381
maximum deviation from the average = 388-381= 7V
Unbalancing = (7/381) x 100 = 1.83% = ACCEPTABLE
Operating out of the indicated limits causes the loss of the
guarantee as well as very serious damages.
page 18
VERIFY TENSIONS – ABSORPTIONS
Check that the temperatures of the fluids are included in the
WORKING LIMITS.
If the controls of the previous paragraphs are positive, it is
possible to restart the unit.
For information on the control panel, refer to the paragraph

AIR FLOW CHECK
The effective unit flow-rate is function of the aeraulic
system characteristics.
It is so necessary to check the air flow-rate and eventually
to proceed with the appropriate calibrations on the system
(dampers, diffusers etc) and on the unit (fan speed control,
pulley calibrations etc in base of the unit type and its
configuration). Before performing the check, make sure that

In the time the working point can change, for example for
the operations on the system (grilles covered by furniture,
closed outlets to modify the air diffusion, exclusion or
addition of the distribution sections etc.) or for lacking
maintenance (clogged air filters, blocked dampers etc) .

LOCAL OR REMOTE MANAGEMENT
The unit can be managed locally from the thermostat or remotely through the use of a RS485 serial line with MODBUS
protocol.
ON
The unit can be switching on/off:
•
by thermostat
•
by digital input (set by parameter)
•
by net (set by parameter)
OPERATION
The unit has 2 set-points: one for heating and one for cooling. The first one is automatically kept lower than the second one
with a difference of at least 1°C.
The regulation module compares ambient temperature with the set-point and tries to keep it as close as possible to it;
therefore, it varies the fan speed, the water capacity or both of them according to the configuration.
The unit operating is enabled only if the water temperature:
•
in WINTER is higher than 30°C
•
in SUMMER is lower than 20°C
OPERATING MODES
AUTOMATIC
The modules automatically commute in cooling or heating mode.
The change occurs according to the input water temperature (2-pipe unit) or return air (4pipe unit.

In this mode, a neutral zone is foreseen when the unit is positioned in a CHANGE OVER status for a time sufficient to probe
water temperature.
The status is displayed by a “CO” flashing.
After that time, if water temperature is out of limit, the H2O alarm is signalled.
Water temperature is detected (therefore, the cooling/heating modes are defined) only if power is demanded. In this operation
type, COOLING and HEATING sets are activated simultaneously; when one of the set is bypassed, water temperature is
detected and the mode is defined.
When thermo-regulator sets are met, the last operation mode is displayed.
The set that is the opposite to the actual one is determined internally by the regulator by a constant that is defined

GENERAL DESCRIPTION
The room thermostat HID-TI2/TI3 (hereafter HID) is a device for recessed installation for the remote control of the unit to which
it is connected. It is therefore not a MODBUS network thermostat.
It can be connected to terminal units equipped with terminal.ROOM or terminal.SPACE electronics and makes it possible to
set:
•
desired humidity/temperature
•
the desired type of ventilation
•
a series of advanced functions for the unit to which it is connected
•
display any error codes that correspond to alarms sent by the adjustment unit.
•
In the HID-TI control there is also a temperature sensor that can be used as a remote sensor for the unit to which it is
connected.
OPERATING MODES
"Normal" operation, HID-TI connected to CLIVET-BUS:
•
the HID thermostat shows the operating status of the unit to which it is connected
•
periodically measure the temperature/humidity in the room where it is installed
•
it is possible to use only the 4 front keys (user programming)
•
"Nolink" operation, HID-TI not connected to CLIVET-BUS:
•
the thermostat is powered by auxiliary power (a battery must be present)
•
it is possible to access hidden keys for installer use
•
it is a temporary mode that allows "advanced programming" of the unit.
INITIAL RESET
Insert the battery (auxiliary power supply) and then press the power on key [A] [A].
All display segments will come on for about 3 seconds. Then the display will show the firmware revision of the device.
If the HID device is not connected to CLIVETBUS within one minute, it will go off.
During this time, you can only use the hidden buttons for use by the installer.
You can also use the HID device without a battery. The initial reset is carried out simply upon connection with the CLIVETBUS.
After the initial reset, upon connection to the CLIVETBUS, the device goes into normal operating mode.
USER PROGRAMMING
User programming makes it possible to:
•
choose the operating mode of the unit (heating, cooling, eco, fan)
•
set the adjustment set point
•
manage the fan speed manually or automatically
•
enable/disable the floating shutter of the air supply (swing)
•
display ambient temperature

DEHUMIDIFICATION
The dehumidification control is managed by the network, which is an upwards system that uses one or more terminal units to
dehumidify.
When the DeumiOn network variable is switched on 1, the unit is forced into cooling mode, even when the temperature set is
met (100% opened valve and minimum ventilation speed).
This occurs to meet the humidity conditions decided by the network (detecting the relevant humidity by a room thermostat).
The dehumidification process shown by the display is stopped when the following occurs:
•
the DeumiOn variable is 0 (humidity conditions are met).
•
Temperature is below the LowLimit, value; therefore, the process can start again only if ambient temperature > setpoint Temp and if there is still a demand.
The dehumidification process can not start if:
•
The operation mode is the Heating mode.
•
The unit is OFF.

DUCTING
Check the fixing screws and the operation of the anti-vibration devices in order to prevent the transmission of vibrations in the
room.
ELECTRIC FANS
Make sure that the fans and the relative protection grids are well fixed.
Check, if possible, the unbalances of the electro-fan evident by noise and anomalous vibrations. Verify that the terminal
protection covers are closed and the cable holders are properly positioned.
ELECTRICAL HEATING ELEMENTS
The convector finned heating elements need to be checked regularly to ensure that they are clean and properly fastened to the
support.
MAINTENANCE INSPECTIONS
Foresee inspection assistance carried out by authorized
centers or by qualified personnel.
The inspections should be carried out at least:
•
- Every year for only the cooling units
•
- Every six months for the cooling and warming
units
The frequency, however, depends on the use: in the event
of frequent use (continuous or very intermittent use, near
the operating limits, etc) or critical use (service necessary)
it is recommended to plan inspections at close intervals.
The inspections to be performed are as follows:
• verify the power supply tension (when emptied or filled)
• inspect the electrical board (status of solenoid starter
contacts, terminal closings, the status of wiring and
relevant insulations)
• inspect the absorption of the single electrical loads
• verify the leakage from the refrigerating circuit
• Verify the protection devices (safety valves, pressure
switches, thermostats, etc.), the adjustment systems,
the control devices (alarm signalizations, probes,
manometers, etc)
• check the operating parameters of the refrigerating
circuit (see the following REFRIGERANT TABLES and
the START-UP section)
For units equipped with safety valves, follow the
Manufacturer’s instructions.
Verify periodically the cleaning of the safety valves and
that oxidative / corrosive phenomena are not present, in
particular for installations near the sea, in industrial areas
or in rooms with a corrosive atmosphere
• verify the cleaning and the efficiency of the exchangers
• inspect the cleaning of the filters (air/water)
PUT AT REST
If a long period of inactivity is foreseen, for example the
winter for the cooling unit, the following is recommended:
• to turn the power off in order to avoid electrical risks or
damages by lightning strike
• to avoid the risk of frosts as shown in the HYDRAULIC
CONNECTIONS section, and, in particular
- to empty or add glycole in the plant sections
subjected to temperatures below zero
- to empty or add glycole in the water heating coils,
also in summer
- to power antifreeze resistances if present
M22740C6-04
01/10/07
If the period of inactivity is particularly long or in the event
of extremely low temperatures, the external fans can be
blocked temporarily; therefore, it is recommended to
switch them on every month in order to avoid seizures or
electrical overloads when the unit will be switched on.
The restarting of the unit has to be carried out by qualified
personnel, in particular, after the winter break for cooling
units or when seasonal switching should be performed.
When restarting, refer to the SWITCHING ON section.
Schedule technical assistance in advance to avoid hitches
and be able to use the installation when necessary.

TROUBLESHOOTING
THE OPERATIONS MUST BE CARRIED OUT BY TECHNICAL QUALIFIED PERSONNEL HAVING THE REQUISITES
UNDER LAW REQUISITES AND IN CONFORMITY WITH THE SAFETY REGULATIONS IN FORCE.
THE INTERVENTIONS WITHIN THE WARRANTY PERIOD WILL BE CARRIED OUT BY AUTHORIZED SERVICE
CENTERS.
BEFORE RESETTING AN ALARM, IDENTIFY AND ELIMINATE ITS CAUSE.
REPEATED RESETS MAY CAUSE SERIOUS DAMAGES.
In certain machine configurations, some safeties may be placed in series and lead back to a single input on the electronic
module.
Therefore, check on the electrical diagram whether the device to which the alarm corresponds has other devices or safeties
connected in series.
