▪ When Emergency is set to Manual and a heat pump failure occurs, the
domestic hot water heating and space heating stops.
To manually recover it via the user interface, go to the Malfunctioning main
menu screen and confirm whether the backup heater can take over the heat load
or not.
We recommend to set Emergency to Automatic if the house is unattended for
longer periods.
# Code
[9.5] N/A
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.
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.

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.
