Constant temperature controller
GB
Introduction1.0 Controllers FWR, FWR are modern designed, microprocessor-driven devices made with
digital and SMT technology.
The controller are provided as a constant temperature controller with actuator designed
for heating applications. The most common use is to control the return temperature in the
boiler. Controller FWR besides controlling the actuator also controls the circulating
pump.
Note: For initial setup see Initial controller setup, page .

Constant temperature controllers are equipped with an innovative solution, which allows
initial setup of the controller in only three steps.
When you connect the controller to the power supply for the first time, the software ver-
sion is shown. Next, the first step appears on the screen.
Note: Selected hydraulic scheme can be later changed with service parameter S..

Initial controller setup3.0
Step  -
Language selection
3.1 Using buttons and you select the required
language.
Press the button to confirm the selected
language. After selecting the language, the control-
ler requires confirmation of the selection by pres-
sing the button .
If you accidentally selected the wrong language, go
back to reset the language by pressing button .
Step  -
Hydraulic scheme selection
3.2 Next, you select a hydraulic scheme for the control-
ler function. Move between schemes by means of
buttons and .
Confirm the selected scheme by pressing the
button .
After you selected the scheme, the controller requi-
res confirmation of the selection by pressing the
button .
If you accidentally selected the wrong scheme, go
back to reset the scheme by pressing button .
Note: Selected mixing valve opening direction can be later changed with service
parameter S..
Step  -
Opening of the mixing valve
3.3 Press icon which indicates the proper direction of
mixing valve opening direction. Between icons you
can move with buttons and .
After you selected the correct direction, the control-
ler requires confirmation of the selection by pres-
sing the button .
If you accidentally selected the wrong mixing valve
opening direction, go back to reset the the selection
by pressing button .

scheme and controller settings.
Note: If you would like to have a specific data display to appear after you stop using
the keyboard then select the desired data with buttons and . Confirm
the selected screen by pressing the button for  seconds.
Note: When you press the button for  seconds, then the display of the temperature
will change from one to two rows and vice versa. On the two line
temperature display, the measured temperature is displayed in the first row
and the required or calculated temperatire in the second row.
