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.
Priority temperature: Defines the
outdoor temperature which below the backup
heater will assist during domestic hot water
heating.
Offset BSH setpoint: Setpoint correction
for domestic hot water temperature: setpoint
correction for the desired 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.
Range: 0°C~20°C
Anti-recycle timer: Minimum time
between two cycles for domestic hot water. The
actual anti-recycling time also depends on setting
[8-04].
Range: 0~10 hours
Remark: The minimum time is 0.5 hours even
when the selected value is 0.
Minimum running timer:
Do NOT change.
