• Integrated constant light level controller with main lighting group
and up to four lighting subgroups with one brightness sensor
• Automatic assignment of the artificial light distribution in the room
to enable constant light level control of the up to five lighting
groups via control charcteristics
• Entry of five brightness values, measured under the lights during
pure daylight, as a parameter in ETS
• Automatic measurement of artificial lighting in the room when it
is dark (without daylight) through targeted on/off switching of the
lighting groups and simultaneous measurement at the brightness
sensor of the detector
