Make sure to perform the following steps
within a relatively short time. the heat
pump switches to high-pressure fault if
the maximum return flow temperature is
exceeded.
make sure that the system is running in heating
mode (ideally in cold condition)…
With the heating curve set low, switch the system
to “forced heating”…
