Reduced
The room controller can work in one of the 4 operating modes "Frost protection",
"Reduced", "Standby" or "Comfort". The operating mode depends on the window
contact, a preset value and the presence sensor.
Window contact
If the window is open, the controller only works in "Frost protection" mode. For all
other functions, the window must be closed. (See window contact).
Change the Mode
The Room FBox input “OccMode“ or register 36 can be used to select the operating
mode.
