T8132C

Programmable Thermostats

Application

The T8132C Programmable Thermostat provides en-

ergy savings for heating and cooling applications. Separate
programs can be set for weekdays and weekends.

Check Table 1 to make sure the T8132C Thermostat is

compatible with the intended system.

TABLE 1—COMPATIBILITY CHART.

LOCATION

Locate the thermostat about 5 ft (1.5m) above the floor

in an area with good air circulation at average temperature.

Do not mount the thermostat where it may be affected by:
— drafts or dead spots behind doors and in corners.
— hot or cold air ducts.
— concealed pipes and chimneys.
— unheated (uncooled) areas such as an outside wall

behind the thermostat.

MOUNT THERMOSTAT MOUNTING PLATE
(FIG. 1)

Position mounting plate on wall. Use spirit level to make

sure mounting plate is level. Use a pencil to mark the two
mounting holes.

Level for appearance only; thermostat functions prop-

erly even when not level. Tighten mounting screws.

Remove mounting plate from wall, and drill 3/16 inch

holes in wall (if drywall) as marked. For firmer material
such as plaster or wood, drill 7/32 inch holes. Gently tap
anchors (provided) into drilled holes until flush with the
wall.

Reposition mounting plate over holes, pulling wires

through wiring opening. Loosely insert two mounting screws
into holes.
