The following diagram illustrates the dimming behaviour for the 3 lighting groups at different levels
of solar radiation. In this example, the TeachIn value was reached at an absolute dimming value of
80% with 450 lux, the influences were both set to medium..
Figure 25: Behavior proportional zone control
Here you can see that depending on the intensity of the sunlight the window side is dimmed down
more than the middle and the wall side less.
If the solar radiation decreases again, all light bands are regulated again to 80%.
If, for example, the light intensity is set from 450 lux to 300 lux (relative dimming, abs. dimming or
scene), the control factors are only used automatically at the correct dimming value. In this case e.g.
at 50%. Without solar radiation, all three light bands then regulate to 300 lux with a dimming value of
50%. With solar radiation, the dimming values below 50% shift accordingly.
The new "proportional master/slave constant light control" eliminates all the disadvantages of the
standard "offset master/slave constant light control" with fixed offset..
