22.5 Constant lighting control with one light group
in the room
The constant lighting control application ensures seamless control of artificial
light based on room brightness. A brightness sensor mounted on the ceiling in a
room acquires the brightness in the room as a sum total of artificial light and
daylight. The previously defined brightness value in the room is maintained at a
constant level. Artificial light is switched off if not needed.
