Code
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.
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].
