[9.6.1] [5‑02] Space heating priority: Defines
whether backup heater will assist the heat
pump during domestic hot water operation.
Enable this function to shorten tank heating
operation time and interruption of the space
heating cycle.
This setting MUST always be 1.
[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].
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.
