22.4 Control for daylight based lighting and
dusk/dawn switching
The application automatically turns off lighting if sufficient daylight is measured
in the room and turns it back on for too little daylight. It requires a brightness
sensor in the room. The automatic function for turning off the lights can also be
locked or enabled.
The application can also be used to implement dawn/dusk switching. The
application turns on lighting in the room at dawn/dusk. An outdoor brightness
sensor can be use instead of placing a brightness sensor in the room.

The parameters luminance, correction factor daylight, and correction factor
artificial light must be determined by the corresponding brightness
measurement in the room and saved to the automation station to ensure
daylight-dependent lighting in the room is operating properly.
The room occupancy has the following commands available to manually
operate lighting:
● Switch on
● Switch off
● Dimming up
● Dimming down
Manual operation by the user can override any existing automation in the room.
Any manual operation must be released to return to automatic mode.
DXR2 applications have the following methods to this end:
● A central scheduler program
● Presence detector detecting non-occupancy
● Central commands from the management station
● By manual operation (first-time switch on or appropriately configured
button)
