UHS5
Programming IR Handset. See below for programmable functions.
UHS7
User IR Handset. This handset can be used for selecting scenes, on, off, raise
and lower. See user guide for full programming details.
For most basic programming operations the UHS5 handset can be used and the following procedures
are based on using this device.
Point the handset at the Sensor and send the required programming commands to the unit as shown
below.
Valid commands will be indicated by a red LED flash. See page 1 for details of other LED responses.
Note: other functions on the UHS5 which are not shown below are not applicable to this product.

When set to On this causes a red LED to flash on the sensor when
it detects movement. Use this feature to check for adequate
sensitivity levels.

Device will not enter programming mode
Check the KNX connections and that the bus segment is powered. The bus voltage should be approximately 30V.
Check that the programming LED illuminates when the button is pressed on the rear of the unit.
What if the lighting does not turn ON?
Check that the unit has been correctly added to the KNX system.
Check that the sensitivity has been correctly set via ETS.
Check any logic functions carefully for intended operation.
If using the constant brightness controller, check that the light level measured by the sensor is lower than the
required threshold.
If the detection range is smaller than expected, check the diagram on page 2. Rotating the sensor slightly may
improve the detection range.
HINT:
The Walk Test LED function can be used to check that the unit is detecting movement in the required area.
What if the lighting does not turn OFF?
Check any logic functions carefully for intended operation.
If using the constant brightness controller, check that the light level measured by the sensor is lower than the
required threshold.
Ensure that the area is left unoccupied for longer than the Time Out Period.
Ensure that the sensor is not adjacent to circulating air, heaters or lamps.
