Note
If you have connected signalling equipment for fault
■
messages (e.g. a buzzer), this will be deactivated
when the fault message is acknowledged.
If the fault can only be rectified at a later date, the
■
fault message is displayed again the next day at
7:00 h and the signalling equipment (if installed) is
switched on again.
If you acknowledge fault message "Heat pump A9",
■
both heating and DHW heating are provided entirely
by the electric booster heater (e.g. instantaneous
heating water heater, if installed). As this is associ-
ated with high electricity costs, we recommend hav-
ing the heat pump checked by your local heating
contractor immediately.
