If the outdoor temperature sensor is not connected or the
cable is short-circuited, the controller assumes that the
outdoor temperature is 0 (zero) °C.
**
Could for example be an extra room temperature sensor.
***
If the sensor is not connected or the cable is short-circuited,
the motorized control valve closes (safety function).
**** Both frost protection methods can be used.
***** Can be set up to react on a closing or an opening contact.
