LUXPRO Power Bridge Thermostat Wire User Instructions
Installation
Take a photo of the wiring at both your thermostat and your furnace. The Power Bridge cannot be used with 2-wire
applications, and requires at least cooling or heating wires and a fan “G” wire at the thermostat. If you have more
wires (multi-stage systems) than are needed for installing the Power Bridge, leave them a reached as they are.
Please review the wiring diagrams on the next page to see how to reconfigure the wires between your furnace/ air
handler and thermostat. If any of your thermostat wiring connections are unclear, please call LUX Technical Support.
AT YOUR FURNACE (AIR HANDLER) – Remove the door panel and locate your control board. Use the additional wire labels to identify each wire from your thermostat with its terminal leader on the control board. If any of your furnace wiring is unclear, please call LUX Technical Support. .

After Set up
Notes:
- If your system provides a second stage of hearing, you may have a W2 wire. You can leave this wire as-is in your furnace and connect it to the W2 block on your new thermostat.
- If you have two R wires (R, Rc, or Rh), please call LUX Technical Support for assistance with your installation.
- Connect your old Y wire to the empty hole next to the blue end of the y-spliter (1). Snap the orange lever shut to secure the wire in its place. Insert the yellow end of the y-spliter into the thermostat’s Y terminal and the green wire into the G terminal.
- Move your old G wire to the C terminal on your thermostat.
