Activate forced electrical back-up
The forced electrical back-up mode enables domestic hot water to be
provided more quickly thanks to the simultaneous operation of the heat
pump and electrical back-up.
1. Activate forced electrical back-up by pressing the key.
The Electrical Heating icon flashes.
When the set temperature of the hot water is reached, the control
panel returns to Automatic mode.
2. It is confirmed after a few seconds.
9.2.6
Set the temperature threshold for the electrical back-up
function
The electrical back-up function is authorised to operate when the outside
temperature falls below a certain threshold. This threshold can be
adjusted.
1. Press the key for 3 seconds.
The Electrical Heating and Set Temp icons flash.
2. Set the temperature threshold with the or keys.
3. Confirm the temperature threshold by pressing the key.
9.2.7
Setting the hysteresis for starting water heating
In order to avoid the thermodynamic water heater from shutting down and
starting up too frequently, it is possible to configure the hysteresis for
activating water heating.
1. Access the activation hysteresis settings by pressing the and
keys simultaneously for 3 seconds.
2. Set the hysteresis with the or keys.
3. Confirm the hysteresis by pressing the key.
For a desired domestic hot water temperature of 55°C with hysteresis of
2°C:
When the domestic hot water temperature is above 57°C, the
thermodynamic water heater is switched off.
When the domestic hot water temperature is below 53°C, the
thermodynamic water heater is switched on.

Recover the refrigerant fluid in the outdoor unit
The refrigerant must be recovered during standard replacements or when
recycling the external unit.
1. Go to the advanced operating mode by simultaneously pressing the
and keys for 3 seconds.
2. Select the parameter which corresponds to Cold mode by pressing
the key several times.
3. Confirm cold mode by pressing the key.
4. Recover the refrigerant from the external unit in accordance with
industry codes of practice.
