Ecoeler 3 Way Motion Sensor Light Switch Installation Guide

Ecoeler 3 Way Motion Sensor Light Switch

SPECS

DESCRIPTION

• The YM2108 Series switch is designed to replace a standard light or fan switch. This device can automatically turn lights or a fan on and off by detecting motion from a heat-emitting source such as a person entering an area. The lights or fan will stay on until no motion is detected and the time delay has expired. This product is ideal for private offices. conference rooms, break rooms, lounges, hallways, stairways or any areas that would benefit from automatic light control. Use indoors only.

COVERAGE AREA

• The sensor must have a clear and unobstructed view of the area. If an object blocks the sensor’s lens, the sensor may not detect motion and may turn the lights or fan off even if someone is in the area. Windows, glass doors, and other transparent barriers will obstruct the sensor’s view and prevent motion detection.
• The coverage area data is measured under the best temperature condition (20 to 25° C), and a higher or lower temperature may not lead to an ideal coverage area (see Figures 1 and 2).

SWITCH OVERVIEW

INSTALLATION AND WIRING

• WARNING: Before installing the YM210B Series switch, disconnect power to the wall switch box by turning off the circuit breaker or removing the fuse for the circuit.

Prepare the Switch Box

1. After the power is turned off at the circuit breaker box, remove the existing wall plate and mounting screws.
2. If applicable, pull the old switch out from the wall box with the attached wires

Prepare the Wires

1. Tag the wires currently connected to the existing switch, so you can easily identify them later.
2. Disconnect the wires.

Wire the Switch

WARNING: Only connect the YM2108 Series switch to a single pole circuit. For three-way switching, purchase the YM2108T Series switch.

1. Twist the existing wires together with the wire leads on the YM2108 Series switch. Wire according to the following:
   

   Circuit Box Wires	Wires on the YM2108 Series Switch
   Power wire (hot)	Black
   Load to power light or fan	Red
   Green or non-insulated (copper) ground wire	Green
   Neutral (required)	White

2. Cap the wires securely using the wire nuts provided (see Figures 4 and 5).

   • Figure 5: Single pole wiring diagram

Finish Installation

1. Insert the switch into the wall box by positioning the lens at the top and the On/Off button at the bottom.
2. Secure the switch to the wall box with the screws provided.
3. Attach the new cover plate and secure it to the wall box with the screws provided.
4. Restore the power to the circuit by turning on the breaker or replacing the fuse.

ADJUSTMENT AND PROGRAMMING

To program the sensor, first remove the cover:

1. Insert a small flathead screwdriver into the notch located on the bottom of the cover below the sensor.
2. Gently lift the screwdriver upward to unlatch the cover (see Figure 6).
   • Figure 6: Lift the screwdriver upward to open the cover.

Adjust Operation Modes

The YM2108 Series switch has two operation modes:

• Vacancy: In vacancy mode (manual on/off, auto-off), press the On/Off button to turn the light or fan on or off like you would a standard switch. The YM2108 Series switch automatically turns off the lights or fan after the time delay.
• Occupancy: In occupancy mode (auto on, auto off with auto reset), the lights or fan turn on automatically when the space is occupied. The YM2108 Series switch automatically turns off the lights or fan after the time delay. If the lights or fan are turned off manually, automatic on is re-enabled when no motion is detected for one minute. This way, the lights or fan will remain off if they were deliberately turned off.
• Adjust the Time Delay
• The Time Delay Dial, labeled as TIME, controls how long the light or fan stays on after no motion is detected. The minimum setting is 15 seconds (fully counterclockwise) and the maximum setting is 30 minutes (fully clockwise). Adjust the setting as desired for your area.
• Adjust the Sensitivity Range of the Sensor
• The Sensor Sensitivity Range Dial, labeled as SENSE, lets you adjust the sensor to avoid unwanted motion detection such as hallway traffic. To decrease sensitivity, turn the setting counterclockwise. To increase sensitivity, turn the setting clockwise. The sensor’s default setting is 3 (75%). You can adjust it from setting 1 (50%) to setting 5 (100%)
• Adjust the Ambient Light Level
• The Ambient Light Level Dial, labeled LIGHT, lets you adjust the sensor to detect whether other light sources (such as sunlight) are enough to light the space without turning on the lights. If you would like the sensor to consider the amount of ambient light in your area, turn the dial counterclockwise. If you would rather not use the ambient light level, leave it on the maximum, default setting (5). This will allow the sensor to turn the light on and off regardless of ambient light.

TROUBLESHOOTING

Lights or Fan Will Not Turn On

Push the On/Off button. The load should turn on. If not:

1. Check the light bulb and/or motor switch on the fan.
2. Turn off the power to the circuit and check the wire connections.

Lights or Fan Will Not Turn Off

• Ensure that no motion is occurring in the coverage area until the set time period.
• Ensure that the sensor is at least 6 ft (2 m) away from devices that are a significant heat source (e.g., heater, heater vent, and high-wattage light bulbs). Hot air currents and heat-radiating devices (such as 100W incandescent bulbs) can cause false detection.
• Push the On/Off button to Off. If the lights or fan do not turn off, turn off the power to the circuit and check wire connections.
• Lights or Fan Turn Off Too Quickly
• The time delay or sensitivity range may be improperly set. Refer to the Adjustment and Programming section.
• Lights or Fan Turn on When Movement Is Detected in Adjacent Area
• If the sensor’s location gives it a view of other areas or hallways, the lights will turn on when motion is detected in those areas. Try adjusting the sensitivity range (refer to the Adjustment and Programming section). You may need to move the sensor to another location.
• Lights or Fan Turn on When the Area is Unoccupied
• The sensor may be mounted too closely to an air conditioning or heating vent. Move the sensor to another location or close the vent.
