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.

Description
[9.6.1]
[5‑02]
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.
[9.6.2]
[5‑03]
Priority temperature
: Used for
calculation of anti-recycling timer. If [5‑02]=1, it
defines the outdoor temperature below which
the backup heater will assist during domestic
hot water heating.
[5‑01] Equilibrium temperature and [5‑03]
Space heating priority temperature are related
to backup heater. So, you must set [5‑03] equal
or a few degrees higher than [5‑01].
