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

Priorities
For systems with an integrated domestic hot water tank
#
N/A [5‑02]
N/A [5‑03]
Defines if gas boiler operation is allowed when
the ambient temperature exceeds the set
equilibrium temperature during space heating
operation.
▪ 0: allowed (default).
▪ 1: NOT allowed.
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)
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.
