movement. The switch-off value should be higher than the brightness value of the ar-
tificially lit room.
For the
daylight dependent motion detection
activate, as required, the objects for
setting the threshold values/hysteresis and waiting period. Then specify the switch-on
value. This is the value, below which the room should be lit in the event of movement.
The switch-off value is derived from the brightness measurement that is performed by
the sensor at the end of the waiting period. Set the waiting period such that after it all
lamps are set to the final brightness. The hysteresis is added to the measured bright-
ness value. If the room brightness later exceeds this total value because the room is
illuminated by daylight, the motion control is switched off.
Settings for all types of motion detection:
The following settings can be made, independent of the motion detection type, i.e. for
"constant" and "brightness dependent" motion recognition.
