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.
Compressor forced off
Compressor forced off mode can be activated to only allow the backup
heater to provide domestic hot water and space heating. When this mode is
activated:
▪ Heat pump operation is NOT possible
▪ Cooling is NOT possible
# Code

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.
# Code
N/A [E-0D]
Priorities
For systems with an integrated domestic hot water tank.
#

Code
Space heating priority: Defines
whether backup heater will assist the heat
pump during domestic hot water operation.
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.
