What is the "Activation level" graph in a Closed loop daylight scene?

Modified on Fri, 17 May 2024 at 08:04 AM

The Activation level defines the dim level the scene comes on to when triggered. 

The yellow tolerance band of the graph shows the target lux you have defined. The orange line on the graph can be adjusted to determine the dimmd level that the scene comes on to depending on the already available lux (i.e. natural lux coming from daylight in the area, or light from luminaires that are not part of the scene) when the scene is triggered.


  • When the scene is activated, if there is less lux available than the target (yellow area), then the scene will come on at the dim level defined by the orange line (left of the yellow band)
  • If there is already "too much" lux available (i.e. more than the desired target lux), the scene will come on at the dimmed level defined by the orange line (right of the yellow area).
  • When the scene is then ON, the sensor will then dim the scene to try to reach and maintain the target lux level.

The activation graph can have points added or removed from it, or the form changes to "square wave" in the same way as a Circadian graph.
