1. Turn the system power OFF from the existing
thermostat. Turn the power to the HVAC
system OFF at the main power panel or at
the furnace.
2. Remove the existing thermostat cover to
access the wires from the wall.
(Some thermostats may have multiple covers, screws
or other locking devices that must be removed or
disengaged.)
3. Locate, but do not disconnect the wires.
(If wires are not visible, they may be connected to the
back of the wall plate. Some models may have doors
that open to expose the wires and mounting screws.)

4. Using the provided stickers, label each wire
according to the chart.
(If the terminals are not labeled, contact
a qualied HVAC technician.)
Note: Wire colors do not always comply
with standards, so wire color should be
ignored. Refer to the existing terminal
designation for proper identication.
*If wires marked Y & C are both present, C may
be a Common wire and should not be used. If
you have a wire marked C, do not connect it
to any terminal. This wire is used only for non-
battery powered thermostats.
5. Do not let the wires slip back into the
wall during disconnection. You may want
to secure the wires to the wall as you
disconnect them. After all wires are labeled,
disconnect each wire and remove the
existing wall plate.

CONNECTING THE WIRES
1. Loosen, but do not remove, the terminal
screws.
Note: A jumper wire has been provided,
connecting the RC and RH terminals for
systems that do not provide both an RH
and RC wire. If you have both an RH and RC
wire, remove this jumper. If you do not have
both an RH and RC wire, leave the jumper in
place.
2. Match and connect the wires from the wall
to the terminals as shown. Wires should be
inserted behind the black terminal shields.
Tighten each screw after the connection has
been made.
(The ends of any extra wires should be wrapped in
electrical tape and carefully pushed back into the wall.)
3. Push any excess wire length back into the
wall to prevent interference.
