Lights do not turn ON with motion (LED does flash).
1. Press and release each button to make sure that the correct lights come ON for each relay. If the lights do NOT turn ON, check
wire connections, especially the Load connection. If the lights turn ON, verify that the correct On Mode is selected in DIP switches
8 and 9.
2. Check to see if light level control is enabled: cover the sensor lens with your hand. If the lights come ON, adjust the light level
setting.
3. If lights still do not turn ON, call 800.879.8585 for technical support.
Lights do not turn ON with motion (LED does not flash).
1. Press and release each button. Make sure that the correct lights come ON for each relay. If the lights turn ON, set PIR and
Ultrasonic Sensitivity to High.
2. Check the wire connections, in particular, the Neutral and Line connections. Verify that connections are tightly secured.
3. If lights still do not turn ON, call 800.879.8585 for technical support.
Lights do not turn OFF.
1. There can be up to a 30 minute time delay after the last motion is detected. To verify proper operation, set DIP switch 1 to ON,
then reset switches 1 and 2 to OFF to start Test Mode. Move out of view of the sensor. The lights should turn OFF in approximately
5 seconds.
2. Verify that the sensor is mounted at least six feet (2 meters) away from any heating/ventilating/air conditioning device that may
cause false detection. Verify that there is no significant heat source (for example, a high wattage light bulb) mounted near the
sensor.
3. Verify that the trimpot is not pointing at "Service" (red LED ON). If so, rotate the trimpot to its middle setting (pointing up). The
Service setting allows users to operate the sensor as a service switch in the unlikely event of a failure.
4. If the lights still do not turn OFF, call 800.879.8585 for technical support.
Sensing motion outside desired areas.
1. Select PIR Sensitivity — Low (DIP switch 4 = ON) if necessary.
2. Mask the PIR sensor's lens to eliminate unwanted coverage area.
3. Adjust the Ultrasonic Sensitivity. Rotate trimpot counterclockwise to reduce sensitivity.
Red LED is lit all the time and the sensor features don't work.
1. Check the Ultrasonic trimpot. If it is set at fully counter-clockwise (MIN) the unit is in Service Mode. Set the trimpot to a mid-range
position.
2. If resetting the trimpot does not clear the LED call technical support.
Wattstopper DW series wall switches fit behind industry standard decorator-style switch cover plates. Cover plates are not included.
Units come in the following colors, which are indicated by the final suffix of the catalog number (shown here in parentheses):
White (-W), Light Almond (-LA), Ivory (-I), Grey (-G), Black (-B), Red (-R).
