STRA-07 for Fancoils
Wiring
STRA-07 has been constructed to be as compact as
possible. Therefore, the controller’s communication input
is not galvanically separated from the supply voltage.
This means that it is important to keep G and G0 in order,
as well as the communication input’s A and B.
All units that share the same transformer and
communication loop must use the same transformerpole for G (terminal 10) and G0 (terminal 11). On the
communication loop the A-terminal (terminal 42) should
only be connected to another A-terminal and the Bterminal (terminal 43) to another B-terminal. Otherwise,
there is great danger of short-circuit with damaged
components as a result.

Display handling
Set point
The display has the following indications:
In Occupied mode, the controller operates from a heating
setpoint (FS = 22°C), or a cooling setpoint (FS = 24°C) that
can be changed using the INCREASE and DECREASE
buttons.
Pressing on INCREASE increases the current setpoint by
0.5°C with each press up to the max. limit (FS = +3°C).
Pressing on DECREASE decreases the current setpoint by
0.5°C with each press down to the min. limit (FS = -3°C).
Switching between heating and cooling setpoints is done
automatically in the controller depending on the heating
and cooling requirement.
Fan control
It is possible to set different parameter values in a
parameter menu in the display, using the buttons on
the controller. You change parameter values with the
INCREASE and DECREASE buttons and confirm changes
with the Occupancy button.
Fan control STRA-07 has a fan button. When you press
the button, a symbol is shown in the display for 10
seconds. During this time, it is possible to change the fan
speed using the INCREASE/DECREASE buttons. The

STRA-07 for Fancoils
Configuration
The controllers are configured via the display through
setting the required parameters. See section Display
handling/Parameter menu. Different applications require
different parameters to be set.
Display: the background lighting is lit (dimmed), and the
occupancy indication is shown (see the chapter Display
handling). The current room temperature (or setpoint
depending on the configuration) is also shown in the
display.
Bypass
Operating modes
STRA-07 has five different operating modes. Through the
occupancy button you are able to switch between three of
them. Occupied is the preset mode.
Off
Operating mode Off means that the controller is not
heating or cooling, and the fans are stopped. However,
the temperature must not drop below the set minimum
temperature (FS=8°C). If it does, the controller will start
heating, and (if a fan is used) start the fan whether it has
been manually stopped or not.
Operating mode Bypass means that the controller controls
the room temperature in the same way as in operating
mode Occupied. The output for forced ventilation is
also active. After a configurable time (FS=2 hours) in
Bypass, the controller automatically returns to the preset
operating mode.
Bypass is normally activated when the Occupancy
button is pressed, via an occupancy detector or a central
command. The operating mode is useful for example in
conference rooms, where many people are present at the
same time for a certain period of time.
Display: The background lighting is not lit, and only OFF
is shown in the display.
Unoccupied
Operating mode Unoccupied means that the room where
the controller is placed is not used for an extended
period of time, for example during holidays or long
weekends. Both heating and cooling are disconnected
and the fans are stopped within a temperature interval
with configurable min/max temperatures (FS min=15°C,
max=30°C).
Display: The background lighting is not lit, but the
current room temperature (or setpoint depending on the
configuration) is shown in the display. OFF is also shown
in the display.
Stand-by
Operating mode Stand-by means that the room is in
an energy save mode and is not used at the moment.
This can be during nights, weekends, evenings etc.
The controller is prepared to change operating mode
to Occupied (comfort) if someone enters the room
(presence). The room temperature is controlled around
the applicable heating and cooling setpoints, with
an extended temperature interval (FS=+/-3°C). For
example, if the heating setpoint=22°C and the cooling
setpoint=24°C, the controller will allow the temperature in
the room to be between 19°C and 27°C. The setpoints can
also be adjusted +/- 3°C via the display.
Display: the background lighting is lit (dimmed).
The occupancy indication and the symbol for forced
ventilation are shown (see the chapter Display handling).
The current room temperature (or setpoint depending on
the configuration) is shown in the display.
Activation of the different operating modes
Preset operating mode
Occupied is the preset operating mode. On models
without display the preset mode can be changed to Standby using dipswitch SW3. OFF (FS): Occupied, ON: Standby. This is configured in the parameter menu in the
display, parameter 45. The operating mode is changed at
the following events:
• When the Occupancy button is pressed (if the controller
has an Occupancy button).
• Activation/deactivation of an occupancy detector on the
digital input.
• CO2 value exceeded.
• Via central control, for example central time control,
central booking system etc.
Occupancy button
Display: the background lighting is lit (dimmed).
STANDBY and the current room temperature (or setpoint
depending on the configuration) are shown in the display.
Occupied
Operating mode Occupied means that the room is in
use and is therefore in a comfort mode. The controller
regulates the room temperature around a heating setpoint
and a cooling setpoint (FS heating setpoint=22°C, cooling
setpoint=24°C). The setpoints can also be adjusted +/- 3°C
locally via the display, or via a central command.

STRA-07 for Fancoils
Shutdown
• Cooling/Cooling
When the Occupancy button is held depressed for more
than 5 seconds, the controller changes operating mode to
”Shutdown” (Off/Unoccupied), regardless of the current
operating mode. Via the display , you can configure
which operating mode, Off or Unoccupied, should be
activated on ”Shutdown”. The factory setting is that
Unoccupied is activated.
For the control states, UO1 is used for the left control
function and UO2 is used for the right control function.
For control states where only one control function is
active (Heating, Heating or cooling via the change-over
function, and Cooling), only UO1 is used.
If you press the Occupancy button for less than 5 seconds
when the controller is in operating mode Shutdown
or the preset operating mode, the controller changes
to operating mode Bypass. If you press the button for
less than 5 seconds when the controller is in Bypass, it
changes operating mode to the Preset operating mode.
In control state Heating, the unit is always a heating
controller and controls according to the heating setpoint
plus/minus the setpoint displacement. The setpoint can be
adjusted in the display.
After a configurable time in Bypass (FS=2 hours), the
controller returns to the preset operating mode.
Like control state Heating but with change-over function,
i. e. when the change-over input is active, the controller
becomes a cooling controller and regulates according
to the basic cooling setpoint plus/minus the setpoint
displacement. See more in the section Change-over.
Heating
For handling of the Occupancy button in combination
with central control, see the section Central control below.
Occupancy detector
Heating or cooling via the change-over function
Heating/Heating
Split output signal
For local control of the operating mode between the
preset operating mode and Bypass, an occupancy detector
is connected.
In control state Heating/Heating, the controller is always
a heating controller and controls according to the basic
heating setpoint plus the setpoint displacement. When
the controller output signal reaches 50%, it is divided
between two actuators. 0…48% of the signal is sent to
actuator 1 and 52…100% of the signal is sent to actuator 2.
See the figure below.
When occupancy is indicated, the controller changes
operating mode to Bypass. If you want to be able to
enter the room temporarily without activating Bypass,
for example to pick something up, you can configure a
powerup delay. This means that Bypass is not activated
until the power-up delay has expired. The Bypass delay
can be set to a value between 0 and 60 minutes (FS=0
min).
In Bypass on presence, there is a switch-off timer, which
means that if there is no occupancy indication during this
time (FS=10 min), the controller will return to the preset
operating mode.
Control states
Heating/Cooling
In control state Heating/Cooling, the controller functions
as a heating controller when the room temperature
is lower than the basic heating setpoint plus half the
neutral zone. The neutral zone is the difference in
temperature between the heating setpoint and the cooling
setpoint. When the room temperature exceeds this limit,
the controller becomes a cooling controller. There is a
hysteresis of 0.1°C when the controller changes from
heating to cooling controller and vice versa. When the
controller is heating, it regulates according to the basic
heating setpoint plus the setpoint displacement, and
when it is cooling according to the basic cooling setpoint
plus the setpoint adjustment.
The controllers can be configured for different control
states/control sequences:
• Heating
• Heating or cooling via the change-over function
• Heating/Heating
• Heating/Cooling
• Heating/Cooling with VAV-control and forced supply
air function
• Heating/Cooling with VAV-control
• Cooling

Thermal actuators
When thermal actuator control has been selected, this
is controlled digitally with time proportional pulses
via output UO…. By pulsing, the opening degree of the
actuator (and its valve) is varied. The period time (in
seconds) is the sum of the on and off output times on the
output. The period time is FS=60s. The controller varies
the on and off output times proportionally depending on
the output signal demand to the actuator.
Actuator exercise
All actuators are exercised. The exercise takes place at
set intervals in hours (FS=23 hours interval). An opening
signal is sent to the actuator for as long time as the run
time has been configured. Then a closing signal is sent for
as long time and the exercise is finished.
Cooling
In control state Cooling, the unit is always a cooling
controller and controls according to the basic cooling
setpoint plus the setpoint displacement.
Cooling/Cooling
Split output signal
In control mode Cooling/Cooling, the controller always
functions as a cooling controller and controls according to
the basic cooling setpoint plus the setpoint displacement.
When the controller output signal reaches 50%, it is
divided between two actuators. 0…48% of the signal is
sent to actuator 1 and 52…100% of the signal is sent to
actuator 2. See the figure below.
Actuators
STRA-07 can be used with two types of actuators:
• Analogue 0…10 V actuators
• Thermal actuators
The actuator type is set via the parameter menu in the
display.
Analogue actuators
The following output signals can be set for analogue
actuators:
• 0…10 V (FS)
• 2…10 V
• 10…2 V
• 10…0 V

STRA-07 for Fancoils
Manual setting of speed I-III means that the speed of the
fan in operating modes Stand-by, Occupied and Bypass
is always the set speed. In the other operating modes, the
fan is demand controlled.
Fan control
In STRA-07 it is possible to control a fan at the following
speeds: Off, Low speed, Medium speed, High speed,
Auto. The fan speed in the Auto position depends on the
controller output signal and the settings for each speed.
Auto control
Manual control
The fan can be manually controlled to work at any speed.
On models with display, you press the fan button once
and a fan symbol is lit for 10 seconds in the display. As
long as the symbol is lit, you can change the fan speed
with the INCREASE/DECREASE buttons. Models without
display have a fan switch.
In auto mode, you can configure if the fan should be
controlled by the heating output, the cooling output, or
both the heating and cooling outputs. When the selected
output exceeds the start value that has been set for each
speed (FS speed 1=20%, speed 2=60%, speed 3=100%),
the fan is activated. It stops when the controller output
signal drops below the set value minus the set hysteresis
(FS=5%).
When the fan speed changes, there is always a minimum
delay (2-3 s) between the inactivation of the output for the
current speed and the activation of the output for the new
speed. Only one fan speed output is defined at a time.
Off/Unoccupied
In operating modes Off and Unoccupied, the fan is
stopped, regardless of the position of the fan switch or the
setting in the display, on condition that the temperature
is within the set temperature limits. If the temperature
is not within the set temperature limits, the fan will be
started in the corresponding Auto position, regardless of
the settings.

Functions description
Parameter Settings
Change-over
Change-over is a function for installations with 2-pipe
systems. It makes it possible to use the same pipe for both
heating and cooling, depending on requirements during
for example the summer (cooling output) and the winter
(heating output).
Control states
To activate the change-over function, control mode
Heating or cooling via the change-over function should be
configured.
STRA-07 has an input for change-over. The input can be
either of the type analogue Pt1000-sensor or a closing
contact connected to a digital input (FS=Pt1000-input).
The Pt1000-sensor is mounted so that it senses the
temperature on the feed wire to the battery. If the
temperature drops below 18°C (FS), change-over is
activated and the heating output, UO1 alt. DO2/DO3 (-Tmodels), is set to cooling. When the temperature exceeds
22°C (FS) the change-over function is deactivated and the
heating output is set to heating.
When using a digital signal input (potential-free contact),
closing the contact switches the change-over function and
sets the heating output, UO1 alt. DO2/DO3 (-T-models),
to cooling. On open contact, the change-over function sets
the heating output to heating.
STRA-07 is delivered with a number of factory settings.
To acquire the desired function, the controller must
be adapted to it’s specific application. This is done
through the parameter menu in the display. Applications
may vary and incorrectly set parameters can effect the
controller and application negatively. Be sure to set the
necessary parameters relevant for your application. If you
experience problems, contact Fläkt Woods TSS controls.
Parameter menu
It is possible to set different parameter values in a
parameter menu. The parameter menu is accessed by
simultaneously holding the INCREASE and DECREASE
buttons depressed for about 5 seconds and then pressing
the INCREASE button twice. The Service indication will
be displayed.
First the display will show the parameter-number 1.
Scroll between parameters by using the INCREASE and
DECREASE buttons.
Press the Occupancy button to select the desired
parameter. The parameter number will be replaced by
the parameter value. The value can be changed using
the INCREASE and DECREASE buttons. If a button is
held depressed the value will start scrolling, first slowly
and then with increasing speed in 3 – 4 steps with 2 – 3
seconds between steps.
Acknowledge/Regret
To acknowledge and store a set parameter value, press
the Occupancy button again, the display then returns to
showing the parameter number. To retrieve the original
value, i.e. the value before change, press the INCREASE
and DECREASE buttons at the same time. The original
value is shown on the display.
It is also possible to control change-over via a central
command. See the variable list in Part IV of this manual.
Condensation detector
Special input CI
There is a special input (CI) on STRA-07 controllers. This
input is intended for Fläkt Woods’s condensation detector,
STRZ-16, and functions internally as a digital input, i. e.
condensation or no condensation.
When the condensation detector is activated, the cooling
control is blocked and the controller is set in neutral
position. When condensation ceases, the controller will
start controlling from the neutral position.
Return
After a certain time, about 1 minute, or when the
INCREASE and DECREASE buttons are pressed at the
same time while in the menu, the display returns to the
normal view. Exit is shown on the display after the last
parameter. The parameter menu is exited by pressing the
Occupancy button while in Exit. Pressing on INCREASE
goes to the first parameter and pressing on DECREASE
goes to the last parameter..
Window Contact
When the window contact has been configurated the
regulator is set to normal operation when window is
closed. If the window is open, the regulator is set in mode
off, heating and cooling outputs are set to 0 V and the
frost protection function is activated.
Frost protection
STRA has built-in frost protection, which is activated
when the controller is not in use. The frost protection
prevents the temperature from dropping below
8°C. Return to normal fan speed and control occurs
automatically when the room temperature exceeds 8°C.
