circuit against freezing. If NOT set correctly, the liquid in the piping can freeze.

# Code 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].
