5. Installation Instructions
5.1 Before You Begin

5.2 Wiring the Dimmer Switch
The X10 Dimmer Switch can be used in single-pole applications (controlling lights from one location) or 3-way/4-way applications (controlling lights from multiple locations). For multi-way applications, a companion switch (sold separately) is required.
- Connect the line (hot) wire to the designated terminal on the dimmer switch.
- Connect the load wire (to the light fixture) to the designated terminal on the dimmer switch.
- Connect the ground wire to the green ground screw on the dimmer switch.
- For multi-way installations, refer to the wiring diagram provided with your companion switch.
Secure all wire connections using screw terminals. Ensure no bare wire is exposed.
5.3 Final Steps
- Carefully push the wired switch into the wall box.
- Mount the switch to the wall box using the provided screws.
- Attach the desired rocker paddle (white or ivory) to the switch.
- Install a compatible wallplate (not included).
- Restore power at the circuit breaker.
6. Operating Instructions
6.1 Local Control
- Turn ON/OFF: Press the top of the rocker to turn the light ON. Press the bottom of the rocker to turn the light OFF.
- BRIGHTEN: Press and hold the top of the rocker to gradually brighten the light. Release when the desired brightness is reached.
- DIM: Press and hold the bottom of the rocker to gradually dim the light. Release when the desired brightness is reached.

6.2 Remote X10 Control
The X10 Dimmer Switch responds to standard X10 commands from compatible X10 controllers (sold separately). Ensure your X10 system is properly configured with the correct house and unit codes for the dimmer switch.
