avoid damage when fitting, the bar on the detector and the terminal block on the
power part must oppose one another with the inscriptions on both unit sections mirror-
inverted. Caution: Do not exert any pressure on the pyramid-shaped plastic insert
(optics) of the unit!
• After applying the operating voltage or after fitting the detector, the unit will be
switched on for 1.5 min (initialization phase), that is, the lighting and HVAC outputs
are deactivated. This is followed by a 9-minute service phase. During that phase, the
output for lighting responds with no delay if the brightness changes. During this period
of time, the proper functioning of the lighting circuitry can be checked by darkening
the space or by pointing a torchlight at the sensor.
• The switch off delay facility for the lighting system is self-learning. It is adapted to the
frequency of movement of people present in the space and, after the movement
detected last, is 5 to 15 minutes (refer to «Functions»).
• The HVAC switch on delay starts when the first movement is detected.
• The HVAC switch off delay starts after the last movement is detected.
• If the detection zone of a detector interferes with that of another detector, the part of
the detector that should not monitor the area of the other detector must be covered
with an adhesive type that is impervious to light.
If there are too many false switching operations, caused by an unfavourable location of
the unit, the potentiometer for the HVAC switch on delay must be set to «N».
This means:
• Switch off delay «Lighting»: 15 min, fixed
• Switch on delay «HVAC»: 0 s, fixed
