Wiring Instructions (Single-Pole Application)

A single-pole application controls lights from one location.

1. Connect the bare copper or green ground wire from the wall box to the green wire on the dimmer.
2. Connect one of the two wires from your wall box (typically black) to the black wire on your new dimmer.
3. Connect the remaining wire from your wall box to the solid red wire on your new dimmer.
4. Cap the remaining red/white striped wire on the dimmer with a wire connector.

Wiring Instructions (3-Way Application)

A 3-way application controls lights from two locations. You will have three wires plus a ground connected to your old switch.

1. Identify and tag the common wire from your old switch (typically connected to a different colored screw, often black).
2. Connect the bare copper or green ground wire from the wall box to the green wire on the dimmer.
3. Connect the tagged common wire from the wall box to the black wire on your new dimmer.
4. Connect the remaining two wires from the wall box (travelers) individually to the two red wires (solid red and red/white striped) on the dimmer. These two red wires are interchangeable.

Adjusting the Dimming Range (Low-End Trim)

To optimize bulb performance and prevent flickering at low light levels, you can adjust the dimmer's low-end trim:

1. Turn the lights ON and move the slide control as far down as it will go.
2. If the lights are flickering or not turning on, locate the small blue lever on the side of the dimmer (behind the wall plate).
3. Adjust the blue lever upwards until the flickering stops or the bulbs turn on consistently at their lowest stable level.
4. Turn the lights OFF and then ON again to confirm the adjustment.
