▪ When Emergency is set to Automatic and a heat pump failure occurs:
- the backup heater automatically takes over the heat load,
- the booster heater in the optional tank automatically takes over the domestic
hot water production.
▪ When Emergency is set to Manual and a heat pump failure occurs, the
domestic hot water operation and space heating stops.
To manually recover it via the user interface, go to the
Malfunctioning main
menu screen and confirm whether the backup heater and/or booster heater can
take over the heat load or not.
To keep energy consumption low, we recommend to set Emergency to auto SH
reduced/DHW off if the house is unattended for longer periods.
