– Group functions can be supplemented by the <group offset> func-
tion, which allows light control with fewer presence detectors.
For details see
7.10 Group offset .
– Group functions can be supplemented by the <Change over groups>
function, which allows light control to be adapted to changing room
situations.
For details see
7.11 Change over groups .
Application example: Groups for room zones
Explanation: Each presence detector provides individual, presence- and
daylight-dependent light control in its room zone. If no one is present, as
in group 2, the lighting remains switched off.
5.1.3 Open-loop light control - Closed-loop light control
Description
Basically, there are two ways the APC control can influence the lighting:
– Open-loop control (the standard case)
How it works: Lighting is regulated to a constant brightness level
depending on the amount of daylight.
Relevant parameter: Brightness setpoint
Technical implementation: Brightness is continuously measured and
compared to the brightness setpoint. Light output is continuously
adjusted so that the difference between the measured brightness
value and the brightness setpoint is minimised.
