Introduction
The Lutron Maestro IR 600-Watt Single-Pole Digital Dimmer with Remote allows you to control your lighting from anywhere in the room, up to 30 feet away, provided there is a clear line of sight. This dimmer switch offers features such as delayed fade-to-off and the ability to recall your favorite lighting level. Indicator lights on the dimmer display the current light level and glow softly in the dark for easy location. This dimmer is designed for use with incandescent or halogen bulbs up to 600-Watt in single-pole applications only. It is not compatible with CFL or LED bulbs.
Setup and Installation
Installation of the Maestro IR dimmer is designed to be straightforward. Always ensure power is turned off at the circuit breaker before beginning any electrical work. Confirm the power is off by testing the switch you intend to replace.
Wiring Instructions
The single-pole dimmer has three connections: a green ground connection and two common screw terminals. Follow these steps for wiring:
- Remove the ground wire from your existing switch and connect it to the green screw terminal on the new dimmer.
- Take one of the remaining wires from your existing switch and connect it to either of the common screw terminals on the dimmer.
- Connect the last remaining wire from your existing switch to the other common screw terminal on the dimmer.
After wiring, install the dimmer and its wall plate into the wall box. The dimmer unit comes in two pieces: a bracket that screws into the wall box and a top piece that snaps into place over the bracket. Verify that all connections are secure and that the dimmer functions correctly before restoring power.

Operating Instructions
The Maestro IR dimmer allows for both manual and remote control of your lighting. The dimmer features a main switch for on/off control and a small rocker switch for adjusting brightness levels. The remote control provides convenient access to these functions from a distance.
Key Features:
- On/Off Control: Use the main button on the dimmer or the remote to turn lights on or off.
- Brightness Adjustment: Use the rocker switch on the dimmer or the dedicated buttons on the remote to brighten or dim lights.
- Delayed Fade-to-Off: Lights will gradually fade off, allowing time to exit the room before darkness.
- Favorite Lighting Level: The silver button on the remote can be programmed to recall your preferred lighting level instantly.
- Indicator Lights: Small LEDs on the dimmer display the current light level and glow softly for visibility in the dark.
Ensure a clear line of sight between the remote and the dimmer for optimal performance, as the remote operates using infrared (IR) technology.
Maintenance
To maintain your Lutron Maestro IR dimmer, ensure the device and wall plate are kept clean. Use a soft, damp cloth for cleaning; avoid abrasive cleaners or solvents. Periodically check the remote control batteries and replace them as needed (2 AAA batteries required for the remote, not included with the dimmer unit).
Troubleshooting
If your dimmer is not functioning as expected, please check the following:
- No Power: Verify that the circuit breaker supplying power to the dimmer is in the 'ON' position.
- Lights Not Dimming/Turning On: Ensure the dimmer is correctly wired according to the installation instructions. Confirm that the bulbs are incandescent or halogen, as this dimmer is not compatible with CFL or LED bulbs.
- Remote Not Working: Check the batteries in the remote control. Ensure there is a clear line of sight between the remote and the dimmer, and that you are within the 30-foot operating range.
- Intermittent Operation: Confirm all wire connections are secure and properly insulated.
For persistent issues, consult a qualified electrician or contact Lutron customer support.
