Brightness measurement
The presence detector measures artifi cial light and daylight
by means of two directed light measurements. Light measu-
rement Z1 measures the brightness in zone 1. In zone 2, light
measurement Z2 measures the brightness. The alignment of
both brightness measurements has to be taken into account
during installation. The installation location is the reference
point for the lighting level. The brightness measurement can
be adapted to the conditions in a room with the room correc-
tion factor.

Each light measurement zone maps a rectangle of about 2 x
4 m on the fl oor. Depending on the operating mode and the
selected detection zone, the light measurements are assigned
as follows:
1-channel (broadcast):
Selection of detection zone Lighting channel
Light measuring zone
Only zone 1
Channel C1 - light
Zone 1
Only zone 2
Channel C1 - light
Zone 2
Zone 1 + zone 2
Channel C1 - light

2-channel (addressable):

The alignment of both zone 1/zone 2 brightness measu-
rements must be taken into account!

Direct light infl uences the light measurement. Avoid pla-
cing fl oor lamps or suspended lighting directly under the
detector.
Constant light control
The detector must be positioned in such a way that it only
detects artifi cial light that it controls itself. Artifi cial light
controlled by other detectors (or manually switched working
lights) will affect the brightness measurement of the detector.
Switching mode
If the brightness measurement is deactivated, the lighting
only switches based on the presence detection function
(brightness setpoint value is set to «Measurement off» via the
remote control).
