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.
 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-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.
