Symptom: Heat pump failure
When the heat pump fails to operate, the backup heater and/or
booster 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:
▪ For EHVH/X: The backup heater will automatically take over the
heat load and domestic hot water production
▪ For EHBH/X: The backup heater will automatically take over the
heat load, and the booster heater in the optional tank 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 backup heater and/or booster heater can take over
the heat load or not.
When the heat pump fails,
