All fi gures are guidance values (Detection areas according to sensNORM
IEC 63180, see data sheet).
Brightness measurement
The presence detector measures artifi cial light and daylight
by means of three directed light measurements. The central
light measurement detects the brightness directly below the
detector (A), while the two other light measurements detect
the brightness close to the window (B) or in the interior (C).
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 correction factor.

Each light measurement area maps a rectangle of about 2.0 x
3.5 m at table height. Depending on the operating mode, the
light measurements are assigned as followed:
•
2-channel: Window light measurement (B) is perma-
nently assigned to lighting channel C1 and interior light
measurement (C) to lighting channel C2
•
3-channel: As with 2-channel, but with free choice
between central light measurement (A) and integral light
measurement (average of light measurements A + B + C)
in the case of lighting channel C3
Switching
Direct light infl uences the light measurement. Avoid placing
fl oor lamps or suspended lighting directly below 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 that
is controlled by other detectors or manually switched work
lighting infl uence the brightness measurement of the detec-
tor. The detector must not be exposed to direct artifi cial light.
Switching operation
If the brightness measurement is deactivated, the light only
comes on when presence is detected (brightness setpoint
value set to “measurement off” via the remote control).
Suitable lamps
The presence detector is designed for the operation of fl uo-
rescent lamps, compact fl uorescent lamps, halogen/incande-
scent lamps and LEDs.

Note window / interior alignment!
Flush-mounted fi tting
The presence detector is fl ush-mounted using a size 1 stan-
dard fl ush-mounting installation socket.
Ceiling installation
A ceiling installation box 73A is available for a simplifi ed
ceiling installation of the presence detector (see accessories).
This also ensures cord grip and contact protection. The instal-
lation diameter is 72 mm (drill diameter 73 mm).
Surface-mounted installation
A back box 110A is available for surface mounted installation
(see accessories).
