to the value selected in field setting [2-03] after a disinfection operation.

injuries, a mixing valve (field supply) shall be installed at the hot water outlet
connection of the domestic hot water tank. This mixing valve shall secure that the
hot water temperature at the hot water tap never rise above a set maximum value.
This maximum allowable hot water temperature shall be selected according to the
applicable legislation.

Heat source settings
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
.
