|---|---|
| Power wire (hot) | Dudu |
| Load to power light or fan | Wura |

| Neutral (required) | Fadaka |
Akiyesi: There is a 30-second warm-up period after each power reset. During this time, the sensor may not respond immediately.
6. Isẹ
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
- Iṣẹ: Automatic ON and Automatic OFF.
- Iwa: The light automatically turns ON when motion is detected and automatically turns OFF after a set time delay when no motion is detected.
- Apẹrẹ fun: High-traffic areas where hands-free operation is desired, such as bathrooms, laundry rooms, and closets.
6.2 Vacancy (VAC) Mode
- Iṣẹ: Manual ON and Automatic OFF.
- Iwa: 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.
- Apẹrẹ fun: 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 PA Ipo
- Iṣẹ: Manual ON and Manual OFF.
- Iwa: 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.
- Apẹrẹ fun: Situations where automatic control is not desired, or for testing purposes.
7. Àwọn Ètò Tí A Lè Ṣe Àtúnṣe
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.

olusin 5: Ti abẹnu view of adjustable settings.

Nọmba 6: Alaye view of customizable settings.
7.1 Adjustable Sensitivity (SENSE)
- Ibiti: Low (20%) to High (100%).
- Iṣẹ: Controls how easily the sensor detects motion.
- Atunṣe: 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)
- Eto: Day, Dim, Dark.
- Iṣẹ: Determines the ambient light level at which the sensor will activate the lights.
- Atunṣe: 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)
- Ibiti: 15 seconds, 1 minute, 5 minutes, 15 minutes, 30 minutes.
- Iṣẹ: Sets how long the light remains ON after the last detected motion.
- Atunṣe: Select the desired time delay using the 'TIME' dial.
8. Ibiti wiwa
The ECOELER Motion Sensor Light Switch utilizes Passive Infrared (PIR) technology to detect human body heat movement. It offers a wide detection area for effective coverage in various room layouts.
