1. Read these instructions carefufly. Failure to follow
these instructions can damage the product or

cause a hazardous condition.

2. Check the ratings given in the instructions and on
the product to make sure the product is suitable for

your application.

3. Installer must be a trained, experienced service
technician.

4. After completing installation, use these instructions
to check out the product operation.

CAUTION

Electrical Hazard.
Can cause electrical shock or equipment

damage.

Disconnect power before beginning installation.

Select ThermostatLocation

Select a _ocation for the thermostat about 5ft (1.5m)
above the floor in an area with good air circulation at

average temperature. See Fig. 1.

Fig. 1. Select thermostat location.

Do not install the thermostat where it can be affected by:

-- Drafts or dead spots behind doors and in corners.

-- Hot or cold air from ducts.

-- Radiant heat from sun or appliances.

-- Concealed pipes and chimneys.

-- Unheated (uncooled) areas such as an outside wall
behind the thermostat.

SeparateWallplate from Thermostat

1. Separate the wallplate from the thermostat. See
Fig. 2.

Install Wallplate (See Fig.3.)

Mount the thermostat hofizontafly on the wall:

1. Pull the wires through the wire hole on the

wallplate.

2. Position the waIIplate on the wall with the arrow
pointing up. Level the waflplate for appearance

only.

3. Use a pencil to mark the mounting holes.

4. Remove the wallplate from the wall and drill

two 3/16-in. holes in the wall (if drywall) as marked.

For firmer material such as plaster, drill two 7/32-in.
holes. Tap the wall anchors (provided) into the

drilled holes until flush with the wall.

5. Pull the wires through the wire hole on the

wallplate and position the wallplate over the wall
anchors.

6. insert the mounting screws into the watl anchors

and tighten.

WIRING

All wiring must comply with local electrical codes and
ordinances. Refer to Table 2 for descriptions of terminal

designations. See Fig. 6-13 for wiring diagrams for
specific equipment applications.

CAUTION

Electrical Hazard.

Can cause electrical shock or equipment
damage.

Disconnect power before wiring.

IMPORTANT

Use f8-22 gauge thermostat wire. Shielded

cable is not required.

1, Loosen the screw terminals that are used for the

application, insert the wires into the terminal block
and tighten each screw terminal. See Fig. 4.

2. Push excess wire back into the wall opening and
restrict wires to the shaded area. See Fig. 5.

3. Plug the wail opening with nonflammable insulation

to prevent drafts from affecting the thermostat.

Table 2. Terminal designation descriptions.

Terminal

Designation Description

Rc (see Note t) Power for cooling--connect to secondary side of cooling system transformer
R (see Note 1) Power for heating--connect to secondary side of heating system transformer
Y Compressor contactor
C (see Note 2) Common wire from secondary side of cooling system transformer

O/B W (see Note 3) Heat relay or changeover valve terminal for heat pumps
G Fan relay

NOTES:

1.

When used in a single-transformer system, leave metal jumper in place between Rc and R. If used on a
two-transformer system, remove metal jumper between Rc and R.

Common wire is optional when thermostat is used with batteries.

If thermostat is configured for a heat pump in the Installer Setup, configure changeover valve

for cool (O-factory setting) or heat (B).
