Choosing the Operating Mode

The thermostat can operate in three different modes: Automatic, Manual or Off. To set the operating mode press either of the AUTO, MAN or OFF buttons. The screen indicates which mode is currently active by displaying AUTO, MAN or OFF.

AUTO (automatic) mode sets the thermostat to follow the built-in temperature program (default or personalised). Operating the thermostat in this mode is the best way to maintain a high level of temperature comfort whilst maximising your energy savings.

MAN (manual) mode sets the thermostat to act as a simple thermostat with a fixed setpoint

throughout the day. The setpoint can be adjusted from 5°C to 35°C by using the Manual backgroundManual background or Manual background buttons. The thermostat will continue to maintain this temperature until another operating mode or temperature is selected.

OFF mode sets the thermostat to control to a minimum temperature setting of 5°C (default) that acts as a frost protection measure for your home.
