„Heat pump“ mode
In this mode, the main heat source used is the heat pump.
When the incoming air temperature is between 10 °C and 40 °C
the appliance will only use the heat pump cycle to heat up the
water.
In case the inlet air temperature is between 3 °C and 10 °C the
unit will only use the heat pump cycle to heat up the water if
during the heating period the water temperature does not drop
below 45 °C.
If the water drops below 45 °C the appliance will use the
electrical heater to increase the water temperature up to 55 °C
and after that it will return to the heat pump cycle.

„Heat pump“ mode
The appliance will return to use the heat pump cycle when
water temperature reaches 55 °C.
„Combi“ mode
This mode uses two heat sources, depending on conditions:
the heat pump or the backup electric element.

„Combi“ mode
If the water temperature inside the tank is less than 60 °C and
the incoming air temperature is between 3 °C and 40 °C, the
appliance will operate in the same way as in the Heat Pump
mode.
The electric heating element will be activated when these
conditions are not achieved.
