Additional functions
The temp. controller has been provided with a large number of other functions in addition to
several possibilities for remote control.
Remote boiler in/out
The temp. controller is equipped with a potential free input for start/stop of the boiler. The
disconnecting signal can be either an “
OFF ” or an “ ON ” switch. With a clamp on the PCB the
temp. controller can be adjusted to either type of signal (see page 30). If start signal is missing
display shows:
Step S 0 ( 0)
Step time 40s
See page 11 for connecting start/stop signal.
Power limitation
The maximum output of the boiler can easily be limited. It is only possible to limit the boiler on a whole
step base. Limitation can be done in the menu or on a potentiometer located on the PCB.
Limitation in menu:
Enter Step mode and press – button. Choose number of power steps and then press E button to save
new value.
Step lim 0(30)
Step time 40s
►
Step lim 0(25)
Step time 40s
For limitation on the PCB, see page 17
Outdoor temperature compensator
The temp. controller is prepared for outdoor temperature compensation. If outdoor sensor is connected,
boiler will calculate and set flow temperature depending on outdoor temperature. Both curve and
parallel are available for fine-tuning flow temperature. When outdoor sensor is connected, display
shows:
TempU 47.0 (50)°C
Power 60kW
Temperature in brackets is calculated flow temperature depending on outdoor temperature. It is
not possible to change calculated temperature when outdoor sensor is connected.
Outdoor t. 24°C
Parallel 0°C
