4.3b Installing the LUX Power Bridge on Heat Pump Systems
Current Wiring:
After Set Up:
 If your system provides a second stage of heating, 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.
 You may or may not have a W1 terminal block on your control board. Do not connect the Power Bridge’s “W” wire to any
terminal block on your control board.
 Connect your old Y wire to the empty hole next to the blue end of the y-splitter (1). Snap the orange lever shut to secure the
wire in its place. Insert the yellow end of the y-splitter 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.
