▪ When Emergency is set to Manual and a heat pump failure occurs, the
domestic hot water heating 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 can take over the heat load
or not.
▪ Alternatively, when
Emergency
is set to:
- auto SH reduced/DHW on , space heating is reduced but domestic hot
water is still available.
- auto SH reduced/DHW off , space heating is reduced and domestic hot
water is NOT available.
- auto SH normal/DHW off , space heating operates as normally but
domestic hot water is NOT available.
Similarly as in
Manual
mode, the unit can take the full load with the backup
heater if the user activates this via the Malfunctioning main menu screen.
To keep energy consumption low, we recommend to set Emergency to auto SH
reduced/DHW off if the house is unattended for longer periods.
