Activating or deactivating open window detection
The thermostat can detect if a window is open in the room
where the fan heater is located. It will automatically adjust
the temperature setpoint to 45 °F to avoid heating the room
unnecessarily.
When an open window is detected, the icon and buttons
ash, then turn blue.
When the device detects that the window is closed, the tem-
perature setpoint will return to its previous state.
To activate or deactivate open window detection:
1. Access menu 5, Open window detection .
2. Select ON to activate or OFF to deactivate open window
detection.
3. Conrm the selection.
