Symptom: Heat pump failure
When the heat pump fails to operate, the optional backup heater and
anti-legionella heater can serve as an emergency heater and either
automatically or non-automatically take over the heat load.
▪ When auto emergency is set to Automatic and a heat pump failure
occurs, the optional backup heater will automatically take over the
heat load, and the anti-legionella heater will automatically take
over the domestic hot water production.
▪ When auto emergency is set to Manual and a heat pump failure
occurs, the domestic hot water and space heating operation will
stop and need to be recovered manually via the user interface. To
recover operation manually, go to the Malfunctioning main menu
screen, where the user interface will then ask you to confirm
whether the optional backup heater or anti-legionella heater can
take over the heat load or not.
When the heat pump fails,
or
will appear on the user
interface.
Possible cause
Corrective action
Heat pump is damaged.
See
"6.1 To display the help text
in case of a malfunction" on

When the backup heater or anti-legionella heater takes
over the heat load, electricity consumption will be
considerably higher.
