INFORMATION
The auto emergency setting can be set in the menu structure of the user interface
only.
INFORMATION
If a heat pump failure occurs and Emergency is set to Manual, the room frost
protection function, the underfloor heating screed dryout function, and the water
pipe antifreeze function will remain active even if the user does NOT confirm
emergency operation.
INFORMATION
If the boiler is connected as auxiliary heat source to the tank (via bivalent coil or via
drain back connection), the boiler and NOT the backup heater operates as
emergency heater, independent of the boiler capacity. For small capacity boilers this
may lead to capacity shortages in case of emergency.
If the boiler is directly connected to the space heating circuit, it does NOT act as
emergency heater.
Compressor forced off
Compressor forced off mode can be activated to only allow the backup
heater or auxiliary boiler to provide domestic hot water and space heating. When
this mode is activated:
▪ Heat pump operation is NOT possible
▪ Cooling is NOT possible

Glycol Filled system
This setting gives the installer the possibility to indicate whether the system is filled
with glycol or water. This is important in case glycol is used to protect the water
circuit against freezing. If NOT set correctly, the liquid in the piping can freeze.
