Auto emergency
When the heat pump fails to operate, the gas boiler can serve as an emergency
back-up heater and either automatically or non-automatically take over the entire
heat load.
▪ When auto emergency is set to Automatic and a heat pump failure occurs, the
boiler will automatically take over the heat load.
▪ When auto emergency is set to
Manual
and a heat pump failure occurs, the
domestic hot water and space heating operations will stop and need to be
recovered manually. The user interface will then ask the user to confirm whether
the boiler can take over the entire heat load or not.
When the heat pump fails, will appear on the user interface. If the house is
unattended for longer periods, we recommend to set [A.6.C]
Emergency to
Automatic .
