Emergency
When the heat pump fails to operate, the backup heater can serve
as an emergency heater. It then takes over the heat load either
automatically or by manual interaction.
▪ When Emergency is set to Automatic and a heat pump failure
occurs, the backup heater automatically takes over the domestic
hot water production and space heating.
▪ 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
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
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
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.
