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.
(Failure to turn off the power to the existing thermostat before
removal could damage your system.)
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. See page
8 for common examples.)
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
Wire Labels 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.
(Any unused wires should be capped with an approved electrical connector,
such as electrical tape.)

5. Tap the plastic anchors into the holes until they are ush with the
wall. (Do not use plastic anchors if you encounter a stud in 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 individually wrapped in electrical
tape and carefully pushed back into the wall.)
3. Push any excess wire length back into the wall to prevent
interference.
