External heater
Emergency
When the heat pump fails to operate, the optional external backup
heater kit 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 heat load.
▪ When
Emergency
is set to
Manual
and a heat pump failure
occurs, the 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.
▪ When
Emergency
is set to
auto SH reduced/DHW off
and a
heat pump failure occurs, space heating is reduced.
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.
