Presence detector
IR24-PC is a 360° presence detector for automatic ventilation control
of HVAC systems. It uses infrared light. The detector has a change-
over output for activation/deactivation of a fan coil controller. It is
intended for ceiling mounting.

Mounting
Loosen the screw and remove the cover. Carefully lift out the electronics
cassette by bending the plastic clips outwards. Lead the cable into the
bottom part. Mount the bottom part on the ceiling. Replace the electronics
cassette and connect the cable to the corresponding terminals (see
Wiring below). Finally, replace the front cover.
Note: Do not touch the infrared sensor in the middle of the electronics
cassette.

On/Off delays
IR24-PC has individually settable On and Off delays. The delays are
designed to provide better energy management of HVAC systems.
The On delay is the time given to the sensor to certify the occupancy
before it activates the fan coil controller. The Off delay is the operating
time for the fan coil after the last detection.
The On and Off delays are set by placing the jumper head on the
corresponding pins according to the table and figure below.

Testing the function
To test the function of the detector, apply power supply and wait for
the detector to warm up (~25 sec.). The LED will blink (long and
short) during the warm-up period. Ensure that the jumper head con-
nectors of the On and Off delays are placed in the "A" position (the
shortest time). Walk across the detection zones at normal speed. The
LED will be lit when the sensor detects the motion.
Note: The LED will blink if a jumper head connector is not properly
placed.
EMC emission and immunity standards
