4.3d Installing the LUX Power Bridge on Heat Only Systems
Current Wiring:
After Set Up:
 For this system type, you will need to connect the Power Bridge’s “Y” wire to the W1 terminal block on your control
board. Re-label the yellow tab on the Power Bridge’s Y wire with one of the included W wire stickers. You will not
use the Power Bridge’s “W” wire for this system.
 Connect your old W 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 W terminal and the green wire
into the G terminal.
 Move your old G wire to the C terminal on your thermostat.
