Indoor unit type
The indoor unit type is displayed, but cannot be adjusted.
Domestic hot water
The tank type is displayed, but cannot be adjusted.
Emergency
When the heat pump fails to operate, the booster 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 booster heater in the 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 heating stops.
To manually recover it via the user interface, go to the
Malfunctioning
main menu screen and confirm whether the
booster heater can take over the heat load or not.
To keep energy consumption low, we recommend to set
Emergency
to
Manual
if the house is unattended for longer periods.
