9.3 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.
9.4 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.
