If this control is replacing a control that
contains mercury in a sealed tube, do not
place your old control in the trash. Dispose of
properly.
Contact your local waste management
authority for instructions regarding recycling
and the proper disposal of an old control.

Electrical Shock or Equipment Damage
Hazard.
Can shock individuals or short equipment
circuitry.
Disconnect power supply before installation.
Select Thermostat Location
Select a location for the thermostat about 5 ft (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.
Mount the thermostat horizontally on the wall:
1. Pull the wires through the wire hole on the wall-
2. Position the wallplate on the wall with the arrow
3. Use a pencil to mark the mounting holes.
4. Remove the wallplate from the wall and drill two
5. Pull the wires through the wire hole on the wall-
6. Insert the mounting scre ws into the wall anchors

— All wiring must agree with applicable codes,
ordinances and regulations.
— Use 18 gauge thermostat wire. Shielded cable
is not required.
— Sensor wires must have a cable separate
from the thermostat control cable.
— Refer to Table 2 for terminal designation
descriptions.

2. Loosen screw terminals used for the application.
3. Insert the wires into the terminal block and
tighten each screw terminal.
4. Push excess wire back into the wall opening and
restrict wires to the shaded area. See Fig. 5.
5. Plug the wall opening with nonflammable insulation to prevent drafts from affecting the thermostat.

NOTES:
1. When used in a single-transformer system,
leave metal jumper wire in place between
RC and R. If used on a two-transformer system, remove metal jumper wire between RC
and R.
2. Common wire is optional when thermostat
is used with batteries. When using separate transformers for heating and cooling,
the common must come from the cooling
transformer.
3. If t hermo stat i s conf igur ed for a heat p ump
in the Installer Setup, configure changeover valve for cool (O-factory setting) or
heat (B).
4. Sensor wires must have a cable separate
from the thermostat control cable.
