8.3 Use of the force function
Example: Lighting with brightness control during the daytime and minimum lighting during the
night.
A brightness controller continuously measures the brightness of the room and controls the
dimmer, to keep the brightness constant.
A dimming value of 20% is configured for forced operation.
In the evening at the close of work, the time switch activates forced operation, which dims down
the brightness to 20%.
During the night, the lighting is switched on for a certain period of time by the night-watchmen
via the central permanent ON function.
In the morning at the start of work, the time switch cancels the forced operation again and the
dimmer is controlled by the brightness control.
