The "Open Window Detection" function enables detecting of an open window by sensing a sud-
den decrease of the temperature in the room. In such a case, the device deactivates the heating

the window has been closed.
To activate this function:
Enter into "Stand-by" mode.
Press the [+] button for 3 seconds.
Press the [+] button to activate / deactivate the function
Press the [Prog] button to commit and return into "Stand-by" mode.

When the device detects that the window is potentially opened, the "Open Window"
icon starts blinking

NOTE - The device could fail in detecting an opened window e.g. if the thermostat is located on
an isolated area of the room and far from air currents or if the thermostat is placed close to an
external heating source, or if the temperature variation in the room is too slow.
