5. Setup and Installation

Important: Before starting, ensure the power to the circuit is turned OFF at the circuit breaker or fuse box to prevent electrical shock.

  1. Turn Off Power: Locate the circuit breaker controlling the light switch you are replacing and turn it off. Verify power is off using a voltage tester.
  2. Remove Old Switch: Carefully remove the existing wall plate and unscrew the old switch from the wall box. Disconnect the wires from the old switch.
  3. Identify Wires: Identify the following wires in your wall box:
    • Live Wire (Black): Carries power from the circuit breaker.
    • Load Wire (Red/Black): Connects to the light fixture.
    • Neutral Wire (White): Required for the motion sensor switch. If not present, consult an electrician.
    • Ground Wire (Green/Bare Copper): For safety.
  4. Wire the New Switch: Connect the wires from the wall box to the DEWENWILS motion sensor switch using the provided wire connectors. Match the colors as follows:
    • Connect the Live Wire from the wall box to the Black wire of the switch.
    • Connect the Load Wire from the wall box to the Red wire of the switch.
    • Connect the Neutral Wire from the wall box to the White wire of the switch.
    • Connect the Ground Wire from the wall box to the Green wire of the switch.

6. Operating Instructions

The DEWENWILS Motion Sensor Light Switch offers two primary operating modes: Automatic (OCC) and Manual. It also features adjustable settings for optimal performance.

6.1 Operating Modes

  • Automatic (OCC) Mode: In this mode, the lights automatically turn ON when motion is detected and turn OFF after a preset time delay when no motion is detected. This is ideal for high-traffic areas like hallways, bathrooms, and storage rooms.
  • Manual Mode: In this mode, the lights can only be controlled manually using the ON/OFF button on the switch. This provides flexibility for situations where automatic control is not desired, such as during cleaning or when continuous light is needed regardless of motion.

6.2 Adjustable Settings

The switch features three adjustable knobs located behind the main button cover. Gently pry off the button cover to access these controls.

  • Time Delay Knob (TIME): Adjusts how long the lights remain ON after the last detected motion. Settings range from 5 seconds (fully counter-clockwise) to 10 minutes (fully clockwise).

  • Sensor Sensitivity Range Knob (SENSE): Adjusts the motion detection range. The default position is typically 65%. Turn clockwise for a larger coverage area (up to 100%) and counter-clockwise for a smaller area (down to 30%).

  • Ambient Light Level Knob (LUX): Determines the ambient light level at which the sensor will activate. Turn the knob counter-clockwise to enable ambient light detection (lights will only turn on if the room is dark enough). To override ambient light detection and have the sensor always activate regardless of light level, leave it at the maximum setting (+).

6.3 LED Indicator

The switch includes an LED indicator. When the load is OFF, the LED is OFF. When the load is ON, the LED is ON. If the switch is manually turned OFF while in auto mode, the LED will blink for 30 seconds, then disable auto-on functionality.

7. Maintenance

The DEWENWILS Motion Sensor Light Switch requires minimal maintenance.

  • Cleaning: To clean the switch, wipe it with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the finish or internal components.
  • Inspection: Periodically check the switch and wall plate for any signs of damage or loose connections. If any issues are found, turn off power at the circuit breaker and address them promptly.

8. Troubleshooting

If you experience issues with your motion sensor light switch, refer to the following common problems and solutions:

ProblemPossible CauseSolution
Lights do not turn ON with motion.
  • Power is off.
  • Incorrect wiring.
  • Sensitivity (SENSE) setting is too low.
  • Ambient light (LUX) setting is too high (sensor thinks it's bright enough).
  • Switch is in Manual Mode.
  • Check circuit breaker.
  • Verify wiring connections (Live, Load, Neutral, Ground).
  • Increase SENSE setting.
  • Adjust LUX setting (turn counter-clockwise) or set to maximum (+) to disable ambient light detection.
  • Switch to Automatic (OCC) Mode.
Lights stay ON too long or turn OFF too quickly.
  • Time Delay (TIME) setting is incorrect.
  • Continuous motion in the detection zone.
  • Adjust TIME setting to desired duration (5 seconds to 10 minutes).
  • Ensure no constant heat sources or movement are within the sensor's view.
Lights turn ON/OFF unexpectedly.
  • Sensitivity (SENSE) setting is too high.
  • Drafts or heat sources (e.g., HVAC vents) causing false triggers.
  • Decrease SENSE setting.
  • Ensure the sensor is not exposed to drafts or direct heat sources.
Detection range is too small or inconsistent.
  • Sensitivity (SENSE) setting is too low.
  • Obstructions blocking the sensor's view.
  • Increase SENSE setting.
  • Ensure a clear line of sight for the sensor.
