3. Select end time of phase
4. Define next heating phase
   • Up to 9 heating phases per day possible
   • After 7 set times, the programming is automatically completed
   • Alternatively, the entry can be ended with an end time of 24:00

Factory settings of the weekly program:

• 00:00–06:00 → 17°C

3. Press the confirmation button.

6. Window-open detection (“Aer”)

If the thermostat detects that the room temperature suddenly drops by 5°C within 5 minutes , this is interpreted as an open window .

• Standard temperature during open window: 15°C
• Standard duration: 10 minutes

Adjust settings:

1. Open menu (long press “G” until “Aer” appears).
2. Use the rotary dial to set the temperature (0.5°C–29.5°C) and duration (0–60 minutes).
3. Press the confirmation button.

💡 Note: If the duration is set to 0, the function is deactivated.

7. Offset temperature (“tOF”)

Since the thermostat measures the temperature directly on the radiator , deviations from the room temperature may occur.

• To compensate for this, an offset of ±5.5°C can be set.

To set the offset:

1. Open menu (press and hold “G” until “tOF” appears).
2. Use the rotary knob to set the desired offset value (-5.5°C to +5.5°C).
3. Press the confirmation button.

💡 Example: If 18°C ​​is reached in the room instead of the desired 20°C , an offset of +2.0°C can be set.

8. Restore factory settings (“rES”)

If you want to reset the thermostat to factory settings :

1. Open menu (long press “G” until “rES” appears).
