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

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

# Code Description
[9.6.1] [5‑02] Space heating priority : Defines
whether backup heater or boiler will assist the
heat pump during domestic hot water
operation.
If no auxiliary boiler is connected to the tank:
For optimal operation and lowest power
consumption, it is strongly recommended to
keep the default setting (
0 ).
If the backup heater operation is limited
([4‑00]=0) and the outdoor temperature is
lower than setting [5‑03], the domestic hot
water will not be heated with the backup
heater.
If an auxiliary boiler is connected to the tank: At
ambient temperatures below [5-03] only the
boiler is used for domestic hot water heating.
