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 0 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.
G) 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.
