NOTE
Only when the EHS system is added to an existing external boiler system, the existing boiler system can
operate as a backup for the heat pump system below the threshold temperature (FSV #4033). It requires
autonomous operation of the existing system (i.e. regarding zone control and pump control) during
temperatures below the threshold value. During backup boiler activation, the heat pump remains inactive.
Release of the backup mode is when FSV #4033 +3˚C is reached.
