Lighting remains continuously in stand-by mode without presence. If the
room brightness is above the desired value, the lighting switches off; if it falls
below, the lighting switches automatically to stand-by mode, even if no one
is present.
4.4 Presence settings
Switch-off delay time presence
The settings remain unchanged (no self-learning effect).
Switch-on delay time presence
When switch-on delay is activated, the telegram sent when movement is de-
tected is delayed by the set value.
4.5 Switch-on behaviour
After every time the bus voltage is switched or the parameters are downloa-
ded by ETS, the detector runs through its start-up phase (indicated by LED).
1. Start-up phase (30sec.)
● LED blinks once per second
● Switching: outlet light receives an ON telegram irrespective of brightness
● Constant light control:
(Value telegram 100 %).
● If there is no presence or sufficient brightness, an OFF telegram is sent
after 30 sec. (Light off).
