The thermostat is forced into Protection when the window is open. The contact can
be connected to multifunctional input X1 or X2. Set P38 or P40 to 3. User
operations are ineffective when window contact is active.
Only one input source must be used, either local input X1 or X2.
The operating mode can be changed to Comfort or Economy based on room
occupancy (room occupied or unoccupied, via presence detector or keycard).
