Code
Space heating priority.
Defines whether backup heater will assist the
heat pump during domestic hot water
operation.
Consequence: Shorter tank heating operation
time and shorter 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.
Space heating priority temperature.
Defines the outdoor temperature which below
the backup heater will assist during domestic
hot water heating.
Setpoint correction for domestic hot water
temperature.
Setpoint correction for the domestic hot water
temperature, to be applied at low outdoor
temperature when space heating priority is
enabled. The corrected (higher) setpoint will
make sure that the total heat capacity of the
water in the tank remains approximately
unchanged, by compensating for the colder
bottom water layer of the tank (because the
heat exchanger coil is not operational) with a
warmer top layer.
