The following operating modes are available:
Comfort mode
In Comfort (ON), the thermostat displays the room temperature value, available user selection and thermostat status. It also maintains the setpoint that can be adjusted via the +/- button.
To save energy, the minimum (P09) and maximum (P10) setpoints can be set to limit the available setpoint range.
Protection mode
In Protection, the thermostat is turned off and the related heating or cooling setpoint is maintained and can be adjusted via control parameters P65 and P66.
Economy mode
When Economy is selected, the thermostat runs in an energy saving mode and maintains the setpoint (P11 or P12), thus saving energy.
If P11 or P12 is set to "Off", the thermostat cannot enter Economy after a 3-second long-press on in Comfort.
Operating mode setting upon power failure
If the thermostat is disconnected from AC 230 V and reconnected:
- If P27 = 0, the unit returns to the operating mode before power failure.
- If P27 = 1, the unit is in Protection mode.
- If P27 = 2, the unit resumes Comfort mode (On).
