Figure 3: Wiring Diagram for Model YM2112.
| Circuit Box Wire | Screw on YM2112 Switch |
|---|---|
| Power wire (hot) | Đen |
| Load to power light or fan | Vàng |
| Green or non-insulated (copper) ground wire | Màu xanh lá |
| Neutral (required) | Bạc |
Ghi chú: There is a 30-second warm-up period after each power reset. During this time, the sensor may not respond immediately.
6. Hoạt động
The ECOELER Motion Sensor Light Switch offers three primary operation modes: Occupancy (OCC), Vacancy (VAC), and OFF. These modes are selected using the internal switches located behind the faceplate.

Figure 4: Operation Modes Diagram.
6.1 Occupancy (OCC) Mode
- Chức năng: Automatic ON and Automatic OFF.
- Hành vi: The light automatically turns ON when motion is detected and automatically turns OFF after a set time delay when no motion is detected.
- Lý tưởng cho: High-traffic areas where hands-free operation is desired, such as bathrooms, laundry rooms, and closets.
6.2 Vacancy (VAC) Mode
- Chức năng: Manual ON and Automatic OFF.
- Hành vi: The light must be manually turned ON by pressing the ON/OFF button. It will then automatically turn OFF after a set time delay when no motion is detected.
- Lý tưởng cho: Areas where you prefer to control when the light turns on, but still want the energy-saving benefit of automatic shut-off, such as offices or living rooms.
6.3 Chế độ TẮT
- Chức năng: Manual ON and Manual OFF.
- Hành vi: The light is controlled entirely manually by pressing the ON/OFF button. Motion detection is disabled for light activation, but the sensor may still detect motion (indicated by an LED flash) without triggering the light.
- Lý tưởng cho: Situations where automatic control is not desired, or for testing purposes.
7. Cài đặt tùy chỉnh
The ECOELER Motion Sensor Light Switch features adjustable settings for optimal performance. These settings are accessed by carefully removing the faceplate to reveal the adjustment dials and switches.

Hình 5: Nội bộ view of adjustable settings.

Hình 6: Chi tiết view of customizable settings.
7.1 Adjustable Sensitivity (SENSE)
- Phạm vi: Low (20%) to High (100%).
- Chức năng: Controls how easily the sensor detects motion.
- Điều chỉnh: Turn the 'SENSE' dial to increase or decrease the detection range and responsiveness. Higher sensitivity detects smaller movements or movements further away.
7.2 Adjustable Light Level (LIGHT)
- Cài đặt: Day, Dim, Dark.
- Chức năng: Determines the ambient light level at which the sensor will activate the lights.
- Điều chỉnh: Select 'Day' for activation regardless of ambient light, 'Dim' for activation in low light conditions (evening), and 'Dark' for activation only in very low light (night).
7.3 Adjustable Time Delay (TIME)
- Phạm vi: 15 seconds, 1 minute, 5 minutes, 15 minutes, 30 minutes.
- Chức năng: Sets how long the light remains ON after the last detected motion.
- Điều chỉnh: Select the desired time delay using the 'TIME' dial.

Ensure neutral wire is connected. 3. Clear any obstructions from the sensor lens. 4. Increase sensitivity setting (refer to Section 7.1). 5. Adjust light level setting (refer to Section 7.2). 6. Switch to OCC mode or manually activate in VAC mode. |
| Light turns ON too frequently or unexpectedly. | 1. Độ nhạy được đặt quá cao. 2. Sensor detecting motion outside desired area (e.g., pets, drafts). 3. Switch is in OCC mode in a high-traffic area. | 1. Decrease sensitivity setting (refer to Section 7.1). 2. Reposition the switch or adjust sensitivity to narrow detection. 3. Consider switching to VAC mode if manual activation is preferred. |
| Light turns OFF too quickly or stays ON too long. | Cài đặt độ trễ thời gian không chính xác. | Adjust the time delay setting to your preference (refer to Section 7.3). |
| Light flickers or does not work with certain bulbs. | Incompatibility with bulb type or wattage vượt quá. | Ensure bulbs are within specified wattage limits (LED/CFL up to 150W, Incandescent/Halogen up to 300W). Try a different type of compatible bulb. |
| Switch does not respond after power restoration. | Warm-up period not completed. | Allow 30 seconds for the sensor to warm up and calibrate after power is restored. |
