Installing your thermostat
Alternate wiring (Heat Pump System)
Use this if your wire labels
don’t match the terminal labels.
Note: You must have a C wire
or equivalent. See page 5.
If you have both an R and Rc wire, unplug the jumper loop by pulling on the wire
loop.
If your old thermostat had both R and RH wires, connect the R wire to the Rc
terminal, the RH wire to the R terminal, and unplug the jumper loop.
If your old thermostat had both V and VR wires, check
honeywellhome.com/wifi-thermostat for help.
If your old thermostat had separate O and B wires, and is controlling a single zone
heat pump system, attach the B wire to the C. If there is more than one thermostat
controlling the system, call Resideo zoning at 8008288367 for wiring assistance.
If your old thermostat had separate Y1, W1, and W2 wires, check
honeywellhome.com/wifi-thermostat for help.
If the old thermostat has separate wires on Aux and E, use a wire nut to attach both
wires to a separate wire. Slide this third wire into the W2-Aux/E terminal.
This is the system monitor. If the monitor finds a problem, you will see an orange
alert button on the thermostat home screen.
