PCB
Control characteristics
PI characteristics with modulating output.
Setting the heating programs
The heating system frost protection (see frost protection function)
applies to all heating programs.
The following heating programs can be selected:
■ Heating and DHW
■ Only DHW
■ Standby mode
Frost protection function
The frost protection function is active in all heating programs.
The burner is switched ON at a boiler water temperature of 5 ºC and
will be switched OFF again at a boiler water temperature of 20 ºC.
The circulation pump will be switched ON simultaneously with the
burner and switched OFF after a delay.
The DHW cylinder will be heated to approx. 20 ºC.
To protect the system against frost, the circulation pump may be star-
ted at certain intervals (up to 24 times per day) for periods of approx.
10 minutes.
Summer mode
Operating program "w"
The burner starts only when the DHW cylinder needs to be heated up
again.
Boiler water temperature sensor
The boiler water temperature sensor is connected to the control unit
and built into the boiler.
