Ordering Information - LEGRAND Wattstopper UT-305-1 User Manual

Unwanted Sensor Activations (LED flashes):
Possible causes
1. The ultrasonic sensitivity may be too high causing detection outside of desired coverage area.
2. Sensor located too close to HVAC or VAV vents with heavy air flow.
3. If LED is flashing rapidly (~10Hz), an overload condition exists. When this is corrected, the sensor will return to normal operation.
Possible solutions
1. Reduce the ultrasonic sensitivity (counterclockwise) as needed (see "Sensor Adjustment").
2. Relocate the sensor.
3. Check the blue wire connection. If necessary, replace the power pack.
