Possible cause
The desired room temperature cannot
be reached.
The weather-dependent curve is set
incorrectly.
In case of third-party gas boiler:
The heat pump cannot reach the
desired room temperature, and the gas
boiler is not allowed to work because of
an installer setting.
Corrective action
Increase the desired leaving water
temperature in accordance with the
heat emitter type. See
thermostat control - Using the leaving
water temperature home
Adjust the weather-dependent curve.
See
"4.8 Weather dependent
4
operation" [
41].
Ask your installer to increase the
equilibrium temperature [5‑01].
Note:
▪
When the outdoor temperature is
higher
than
the
temperature [5‑01], the gas boiler is
not allowed to work.
▪
Do
not
set
the
temperature [5‑01] too high, because
this would result in much less heat
pump operation.
