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.

INSTALLING THE WALL PLATE
1. Remove the wall plate from the new
thermostat by pressing the release tab on the
bottom of the thermostat.
2. Position the new wall plate on the wall and
pull the labeled wires through the opening.
3. If the existing holes do not match those

existing holes, visually level the wall plate
and mark the wall for two holes.

5. Tap the plastic anchors into the holes until
they are ush with the wall.

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.
