Thermostat does not work on Heat Pumps with auxiliary/backup heat.
We are here to help. Call 1-800-468-1502 for wiring assistance.
Alternate Wiring
1. If wires will be connected to both R and Rc terminals, remove metal jumper.
2. Do not use C or X. Wrap bare end of wire with electrical tape.
3. If you have a heat pump without auxiliary/backup heat connect O or B, not both. If you do not have a heat
pump, do not connect B. Wrap bare end of wire with electrical tape.
4. Place a jumper (piece of wire) between Y and W if you are using a heat pump without auxiliary/backup heat.
