5.2. Constant light control
5.2.1. Description
Constant light control makes it possible to match the lighting in a room to the naturally available ambient light. To do this, the
ambient light sensor monitors the illuminance in the room, compares it to the previously set brightness setpoint and dims the light
until the received illuminance matches the desired setpoint.
If several basicDIM DGC sensors are used, constant light control is linked to the sensor with the highest address. In order to change
this and use another sensor for the constant light control, do the following:
Where ambient light values are high, this can result in ambient light-based bright-out and bright-in. If the measured illuminance
exceeds a specified threshold value for a period of time that is longer than the specified delay time, the luminaire group is switched off
by the DALI basicDIM DGC. This also applies in cases where motion is detected in the room. The luminaire group is switched on again
as soon as the measured illuminance falls below the brightness setpoint.
The Constant light control function ensures that the illuminance in the room remains constant and changes due to variable amounts
of ambient light in the room are compensated for. This produces greater comfort, illumination is always properly adjusted, and it also
saves energy.
Detection area of the ambient light sensor
The detection area of the sensor is sized so that a relatively large area, rather than just an individual location on the task area, is
covered and assessed. This ensures that objects being moved around cannot cause incorrect measurements.
Go to the desired sensor with the basicDIM DGC Programmer or the REMOTECONTROL IR6

CAUTION!
If motion detection is deactivated, the light will not be automatically switched on again.
