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
started 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.
Boiler water temperature sensor
The boiler water temperature sensor is connected to the control unit
and built into the boiler.
Specification
Sensor type Viessmann NTC 10 kΩ at 25 °C
Permissible ambient temperature
– Operation 0 to +130 °C

Cylinder temperature sensor
For Vitodens with loading cylinder or solar cylinder also an additional
outlet temperature sensor.
These sensors are connected to the control unit and built into the
boiler or cylinder.
