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 wifithermostat.com 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 Honeywell zoning at 800-828-8367 for wiring assistance.

If your old thermostat had separate Y1, W1, and W2 wires, check

wifithermostat.com 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.
