STEP 1. Remove the Old Thermostat.
1. Cover
2. Base, which you can remove by loosening all screws

Remove the Old Thermostat
Important: Do not let wires fall back into the wall.
1. Remove the front cover of the old thermostat.
2. With wires still attached, remove wall plate from the
wall by loosening the screws. If the old thermostat has a wall
mounting plate, remove both the thermostat and the wall
mounting plate.
3. Identify each wire attached to the old thermostat as shown in the
diagram below. Before removing wires from old thermostat,
label each wire with the letter on the old thermostat or document
the color of wire going into each terminal in the table located on
the back cover of this manual.
4. Disconnect the wires from the old thermostat one at a time.

You may want to wrap the wires
around a pencil to keep them from
falling back into the wall.

Take care when securing and routing wires so they do not short to
adjacent terminals or rear of thermostat. Personal injury and/or
property damage may occur.
CAUTION
STEP 2. Mount the New Thermostat
1. Unpack the thermostat and separate the mounting plate from the
thermostat. Remove the packing material from the thermostat.
Gently pull the thermostat straight off of the base. Hold the back
of the thermostat by the lower corners with one hand, and pull
the wall plate off with the other hand.
2. Feed thermostat wires through rectangular hole between the
terminal blocks in the thermostat wall plate.
Mount the new thermostat
NOTE: Forcing or prying on the thermostat will cause damage to the unit.

3. Once you have established the desired location of the thermostat,
use a pencil, and the wall plate as a template, to mark the
location of the mounting holes on your wall.
4. Move wall plate out of the way and drill two holes using a
3/16" drill bit.
5. Feed the thermostat wires through the rectangular hole and
fasten wall plate loosely to wall using two mounting screws in
mounting holes.
If desired, place a level against bottom of the wall plate and
adjust until level before tightening screws (leveling is for
appearance only and does not affect thermostat operation).
If you are using existing mounting holes, or if holes drilled are
too large and do not allow you to tighten base snugly, use
plastic wall anchors included with the product.
6. Connect wires to the thermostat wall plate. The image below
shows the location of the wire terminals. Each terminal is
labeled with a letter or letter number combination.

Connect wires as follows:
• If necessary, strip insulation about 3/8 inch from the end
of the wire.
• Use the table you previously filled out on the back of the
installation manual (or the wiring chart on page 20) to locate
the correct terminal for each wire connection.
• Bend the wire slightly, insert the wire under the contact plate,
and use a small flat head screwdriver to secure the wire
into place.
7. Push excess wire into wall and plug hole with a fire resistant
material (such as fiberglass insulation) to prevent drafts from
affecting thermostat operation.
8 Fasten thermostat to wall plate using the quick connect feature.
Make sure the retention tabs on the wall plate are in line with
the retention slots on the thermostat. Gently press the
thermostat onto the wall plate until you hear a clicking sound.
If the thermostat does not easily click do not press with
excessive force or damage could occur to the product.
9. Turn power back on at the breaker.
