Brightness
The parameter "
Light channels influence brightness measurement
" can be used to set whether
several light sources in a room influence each other or not.
Example for setting "Yes":
Light channel 1 and 2 react to the basic setting for brightness (general
setting) and switch 3 independent light sources in the room. If, for example, light channel 1 is
switched on via an external button and the brightness value of the switch-on threshold is
exceeded, the other two channels automatically become "brightness-independent" and can
therefore also switch their lamps via motion.
Example for setting "
No": If several light sources are switched in a staircase with one detector,
but the positions of these sources have no influence on each other (e.g., indirect LED lighting),
each light group can be set to "Basic setting" of the switch-on threshold. If it is now bright due to
daylight and the switch-on threshold is exceeded, all indirect LED lights should also no longer
switch on.
