when the ambient temperature exceeds a certain point (e.g. 5°C). This can be
useful to avoid too much gas boiler operation in case of incorrect settings. When
an equilibrium temperature is set, domestic hot water operation is NEVER
prohibited.
# Code Description
N/A [5‑00] Equilibrium.
Deactivate the gas boiler above the equilibrium
temperature for space heating?
▪ 0: No (default)
▪ 1: Yes
N/A [5‑01] Equilibrium temp.
When the ambient temperature is higher than
this temperature, the gas boiler is NOT allowed
to work. Only applicable if [5‑00] is set to 1.
Range: –15°C~35°C (default: 5°C)
System settings
Priorities
For systems with an integrated domestic hot water tank
# Code Description
N/A [5‑02] 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.
N/A [5‑03] Space heating priority temperature.
Defines the outdoor temperature which below
the backup heater will assist during domestic
hot water heating.
