Lutron Maestro Motion Sensor Light Switch

1. Introduction

The Lutron Maestro Motion Sensor Light Switch, model MS-OPS2-LA, provides automatic lighting control for various spaces such as bathrooms, garages, laundry rooms, and closets. This device enhances convenience and promotes energy savings by automatically turning lights on when motion is detected and off after a period of inactivity. It is compatible with all bulb types, including CFL and LED, and is designed for single-pole applications without requiring a neutral wire.

The sensor incorporates Advanced XCT sensing technology to detect fine motions, preventing lights from turning off inadvertently when a room is occupied. It also features patented ambient light detection, ensuring lights only activate when natural daylight is insufficient.

2. Safety Information

WARNING: Risk of Electric Shock. Improper installation can result in serious injury or death. Always turn off power at the circuit breaker or fuse box before installing or servicing this device. Consult a qualified electrician if you are unsure about any part of the installation process.

• Install in accordance with all national and local electrical codes.
• Do not use with loads exceeding the specified ratings.
• This product is for indoor use only.
• Ensure all wire connections are secure.

3. Package Contents

The package for the Lutron Maestro Motion Sensor Light Switch (MS-OPS2-LA) typically includes:

• One (1) Lutron Maestro Motion Sensor Switch (MS-OPS2-LA)
• Wiring hardware (e.g., wire connectors)
• Instruction sheet

Note: A coordinating wallplate is sold separately and is not included with the sensor switch.

4. Setup and Installation

Installation of the Maestro Motion Sensor Switch is designed to be straightforward, typically taking around 15 minutes. This switch is for single-pole applications only and does not require a neutral wire, utilizing the ground wire for installation if no neutral is available.

4.1. Tools Required

• Flathead screwdriver
• Phillips head screwdriver
• Wire strippers/cutters
• Voltage tester

4.2. Installation Steps

1. Turn Off Power: Locate the circuit breaker or fuse that controls the light switch you are replacing. Turn off the power completely to avoid electrical shock. Verify power is off using a voltage tester.
2. Remove Existing Switch: Unscrew and carefully remove the existing wallplate and light switch from the wall box. Disconnect the wires from the old switch.
3. Identify Wires: In a single-pole application, you will typically find two wires connected to the switch (load and line) and a bare copper or green ground wire. This Maestro switch does not require a neutral wire.
4. Wire the Maestro Switch:
   • Connect the green ground wire from the wall box to the green wire on the Maestro switch.
   • Connect the line wire (incoming power) from the wall box to one of the black wires on the Maestro switch.
   • Connect the load wire (to the light fixture) from the wall box to the other black wire on the Maestro switch.
   • Secure all connections with wire connectors.
5. Mount the Switch: Carefully fold the wires into the wall box, ensuring they are not pinched. Mount the Maestro switch into the wall box using the provided screws.
6. Install Wallplate: Attach the coordinating wallplate (sold separately) over the switch.
7. Restore Power: Turn the power back on at the circuit breaker.

5. Operating Instructions

The Lutron Maestro Motion Sensor Light Switch offers both automatic and manual control options.

5.1. Automatic Operation (Occupancy Mode)

In Occupancy Mode (default setting), the lights will automatically turn ON when you enter the room and automatically turn OFF after a set time delay once the room is vacant. The sensor's advanced technology detects motion up to 30 feet away, covering up to 900 square feet.

5.2. Manual Control

You can manually turn the lights ON or OFF at any time by pressing the main button on the switch. If the lights are manually turned OFF, they will remain off until motion is detected again or until manually turned ON.

5.3. Smart Light Detection

The switch senses ambient daylight in the room. If sufficient natural light is present, the lights will remain off even if motion is detected, further conserving energy. The sensor learns your preferred light levels over time to optimize this function.

6. Programming Modes

The Maestro sensor switch can be configured for different operational modes and time delays to suit your needs.

6.1. Occupancy Mode (Auto ON, Auto OFF)

This is the default setting. Lights turn on automatically when motion is detected and turn off automatically after the set time delay when the room is vacant.

6.2. Vacancy Mode (Manual ON, Auto OFF)

In Vacancy Mode, you manually turn the lights ON when entering the room. The sensor will then automatically turn the lights OFF after the set time delay when the room becomes vacant. This mode is often preferred for bedrooms or rooms with pets to prevent unintended light activation.

6.3. Time Delay Settings

The time delay before lights turn off after no motion is detected can be programmed. Common settings include 1, 5, 15, or 30 minutes. Refer to the detailed programming instructions included with your product for specific steps on adjusting these settings.

Typically, programming involves a sequence of button presses and holds on the switch. For example, to change the time delay, you might press and hold the main button until an indicator light blinks, then press it a certain number of times to select the desired delay.

7. Troubleshooting

If you encounter issues with your Maestro Motion Sensor Light Switch, consider the following common solutions:

• Lights do not turn ON automatically:
  • Ensure power is restored at the circuit breaker.
  • Check wiring connections for security.
  • Verify the switch is in Occupancy Mode (Auto ON).
  • Confirm the sensor lens is not obstructed.
  • Check if there is too much ambient daylight, preventing activation.
• Lights do not turn OFF automatically:
  • Ensure the time delay setting is appropriate (e.g., not set to 30 minutes if you expect a shorter delay).
  • Check for continuous motion within the sensor's range, including subtle movements or drafts that might trigger it.
  • Verify the switch is not stuck in a manual ON state.
• Sensor sensitivity issues:
  • Adjust the sensor's sensitivity settings if available (refer to product-specific programming instructions).
  • Ensure the sensor is not positioned where it can detect motion outside the intended area (e.g., through a doorway).
