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 8008288367 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.
