5.3. Presence control
5.3.1. Description
Presence-based control makes it possible to link illuminance to the presence or absence of people. The light is switched on as soon as
a person enters a room. When the person leaves, the light is set to a predefined light value after a certain time lapse. Presence-based
control offers the benefits of saving energy as well as the convenience of automatic lighting control.
Detection area of the motion sensor
The detection area of the motion sensor consists of a pattern of various measurement fields. The following conditions must be met in
order for an object to be detected reliably:
The diameter of the detection area depends on the detection angle of the sensor and the height at which it is mounted. The mounting
height also has an effect on the sensor's accuracy.

NOTICE
The presence-based control of the basicDIM DGC sensors reacts to moving thermal radiation from people. Other heat sources (e.g.
photocopiers, radiators, etc.) may have an adverse effect on presence-based control. Make sure that there are no other heat
sources in the immediate vicinity of the sensor.
The object must move from one measurement field to another

The temperature of the object must be different from the background temperature
