INFORMATION
If a heat pump failure occurs and Emergency is not set to Automatic (setting 1),
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.
HP forced off
HP forced off mode can be activated to allow the backup heater to provide
domestic hot water and space heating. This is, for example, useful when the brine
circuit is not yet ready to be used. Cooling is NOT possible when this mode is
activated.

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.
