Switching Contact «Lighting»
The switching behavior is controlled by presence and
by daylight. The contact closes in case of darkness and
presence, and opens in case of brightness or absence. The
minimum switch off delay “2min. - 15 min.” and the
desired brightness switching level “Lux” can be adjus-
ted. Depending on the occupants’ behavior the module
is able to automatically extend the switch off delay to a
maximum of 15 minutes or reduce it to the minimum set
time. The delay time is re-started on detection of move-ment. The switch-off delay time does not change with a setting of 2min.
Important: The ECO-IR is designed for use with
fluorescent lights (FL/PL). Incandescent or halo-
gen lights disturb the function of the detector.
Switching Contact «HVAC»
The HVAC control is accomplished by means of a poten-
tial-free relay. The switching behavior is controlled only
by presence, not by brightness. In case of presence, the
contact is closed. The desired switch off delay is infinite-
ly variable between 1 and 60 minutes. The delay time is
re-started on detection of movement.

> 3.5 m the sensitivity of the detector is limited and
the overall permitted load does not change. Brightness
walking movements are required for detection.
threshold and switch-off time delay must be set for each detector individually.
The above figure shows the detection range in side (top)
and top (bottom) view. Note that the ranges in which
seated persons and walking persons are detected differ in

The recommended mounting height is 2m - 3.5m.
The sensitivity of the detector decreases with increasing mounting height. From a mounting height of 4 m walking movements are required for detection, and the detection ranges of multiple detectors should overlap in their fringe

Mounting kit Quick-Fix
The unit can be flush-mounted into suspended ceilings
using the QUICKFIX mounting kit.
Important: The voltage supply of the detec-
tor must not be interrupted
Adjustments on the Sensor Module (see fig. on the left)
1) Switch off delay for HVAC system (minutes)
2) Switch off delay for lighting system (minutes)
3) Brightness threshold (lux)
