1. Introduction
The TOPGREENER TSOS5-W is an in-wall Passive Infrared (PIR) motion sensor light switch designed to automatically control lighting, fans, and motors based on occupancy detection. This single-pole switch requires a neutral wire for proper operation and offers AUTO, ON, and OFF modes for flexible control. It is suitable for various indoor applications, providing convenience and energy savings.
2. Important Safety Information
WARNING: To avoid fire, shock, or death, turn off power at the circuit breaker or fuse and test that the power is off before wiring. Installation should be performed by a qualified electrician or a person with electrical knowledge.
- This device requires a neutral wire for installation. Verify the presence of a neutral wire in your electrical box before proceeding.
- For single-pole use only. Do not use in 3-way or multi-way switch configurations.
- Do not exceed the maximum load ratings: CFL/LED: 150W; Incandescent/Halogen: 500W; Motor: 1/8 HP; Fluorescent 500VA.
- Ensure all wire connections are secure and properly insulated.
- Indoor use only.

Before You Begin: Ensure power is OFF at the circuit breaker. This device requires a neutral wire. If you are unsure about your wiring, consult a qualified electrician.
5.1 Wiring Diagram
The TSOS5-W switch has four wires for connection: Line (Hot), Load, Neutral, and Ground.
- Black Wire: Connects to the Line (Hot) wire from the electrical box.
- Red Wire: Connects to the Load wire (to the light fixture/fan).
- White Wire: Connects to the Neutral wire from the electrical box.
- Green Wire: Connects to the Ground wire from the electrical box.

5.2 Step-by-Step Installation
- Turn Off Power: Locate the circuit breaker that controls the power to the switch box and turn it OFF. Verify power is off using a voltage tester.
- Remove Old Switch: Carefully remove the existing wall plate and switch from the electrical box. Disconnect the wires from the old switch.
- Identify Wires: Identify the Line (Hot), Load, Neutral, and Ground wires in your electrical box. The neutral wire is typically white. If you are unsure, consult a qualified electrician.
- Connect Wires: Using the provided wire nuts, connect the wires from the TSOS5-W switch to the corresponding wires in the electrical box:
- Black switch wire to Line (Hot) wire.
- Red switch wire to Load wire.
- White switch wire to Neutral wire.
- Green switch wire to Ground wire.
- Mount Switch: Carefully fold the wires into the electrical box and secure the TSOS5-W switch to the box using the mounting screws.
- Install Wall Plate: Attach the wall plate (sold separately) over the switch.
- Restore Power: Turn the power back ON at the circuit breaker.
6. Operation
The TSOS5-W features a slider switch for mode selection and adjustable dials for sensitivity and time delay, located behind the faceplate.
6.1 Mode Selection

Figure 3: The OFF-AUTO-ON slider switch for mode selection.
- AUTO Mode (Occupancy Sensor): In this mode, the switch automatically turns lights ON when motion is detected and OFF after a set time delay when no motion is detected. This is the primary energy-saving mode.
- ON Mode: This mode overrides the sensor, keeping the lights ON continuously, similar to a standard light switch.
- OFF Mode: This mode overrides the sensor, keeping the lights OFF continuously, similar to a standard light switch.
6.2 Adjusting Settings (Behind Faceplate)
To access the adjustment dials, carefully remove the faceplate of the switch. You will find dials for Time Delay and Sensitivity.
- Time Delay: This setting determines how long the lights remain ON after the last detected motion. Adjustable options include 15 seconds (test mode), 10 minutes, 20 minutes, and 30 minutes. Rotate the dial to select the desired delay.
- Sensitivity: This setting controls the sensor's responsiveness to motion. It can be adjusted from 30% to 100%. A higher sensitivity setting will detect smaller movements or movements at a greater distance. Rotate the dial to adjust.

7. Troubleshooting
| Problem | Possible Cause / Solution |
|---|---|
| Lights do not turn ON/OFF or device does not work after installation. |
|
| Lights turn ON unexpectedly or stay ON too long. |
|
| Lights do not turn ON when motion is detected. |
|
| Cannot set time delay less than 10 minutes. |
