APPLICATION

The TE86S Thermostat provides universal replacement of single-stage, 24Vac (20 mA to 1.5A) thermostats
used in electric, gas, and oil heating and cooling systems. This thermostat is mercury free and requires no
batteries. The thermostat also can be used to control single stage heat pumps.

The TE86S uses advanced proportional plus integral (P+I) control for optimum temperature control and
comfort.

INSTALLATION

Read these instructions thoroughly before installing
product. Failure to follow these instructions could
damage the product or cause a hazardous condition.
Check the voltage and current ratings on the product
to ensure that it is suitable for your application.
Installer must be a trained, experienced service
technician. Check product for proper operation after
installation.

CAUTION

Damage to heating and cooling system may occur.
Disconnect power from the equipment at the main
breaker/fuse block while installing the thermostat.

Mounting Location.

Mount the thermostat approximately 5 ft. (1.5m)
above the floor in a location that is free from direct
sunlight, heat from appliances, hot or cold air from
ducts, concealed pipes and chimneys, and drafts or
dead spots behind doors or in corners. Do not mount
on exterior wall, if possible. Failure to locate
thermostat mounting as indicated will result in poor
temperature control.
NOTE: Level thermostat mounting is for appearance
only and is not required for proper thermostat
operation.

Using back plate as a guide, mark two mounting
holes on the wall. Drill two mounting holes. Place
anchors (provided) into the holes until flush with
the hole. Position back plate on the wall and
thread the wires from the heating and cooling
equipment through the wiring hole. Holding the
back plate in place on the wall, secure it to the
wall using mounting screws (provided).
