SELECTING THERMOSTAT LOCATION

The proper location of the room thermostat is most important to insure that

it will provide a comfortable home temperature. Observe the following general
rules when selecting a location:

1. Locate it about 5 ft. above the floor with a free flow of air.

2. Install it on a partitioning wall, not on an outside wall.

3. Never expose it to direct light or radiation from lamps, sun, fireplaces, etc.

4. Avoid locations close to doors that lead outside, windows, or adjoining

outside walls.

5. Avoid locations close to radiators, warm air registers, or in the direct path of

heat from them.

6. Make sure there are no pipes or duct work in that part of the wall chosen for

the thermostat location.

7. Never locate it in a room that is warmer or cooler than the rest of the home

such as kitchen or hallway or on the opposite side of the wall of a cold or
unused room.

8. The living or dining room is normally a good location, provided there is no

cooking range or refrigerator on opposite side of wall.

INSTALLATION

1. Remove cover from thermostat by pulling outward. Pull thermostat wires

through small holes beside terminal screws on thermostat base and connect
wires to proper terminal screws per wiring diagrams. Note that on some
models wire leads may be connected to terminal screws on

back

of base.

2.

The thermostat can either be mounted to a standard horizontal outlet box
or mounted directly to the wall. The thermostat must be level to assure
optimum performance.

Place level on top of thermostat base and mark hole

locations for mounting screws.Push excess wire into wall or switch box and

plug up hole to prevent drafts from affecting thermostat operation.

Then

attach thermostat base loosely to wall with the two screws provided.

3. Again place level on top of thermostat base to be sure it is level. Then tighten

mounting screws securely and snap on thermostat cover.

HEATING ANTICIPATOR

The heating side of this
thermostat is equipped
with an adjustable heater.

Set heater indicator to
match the current rating of the primary control.

The heater may be adjusted

for current ratings from .2 to 1.2 Amp.

Additional adjustments, if necessary, may be made as follows:

BURNER CYCLES TOO LONG -

Set adjustable heater to a slightly lower dial

setting (1/2 division).

BURNER CYCLES TOO SHORT -

Set adjustable heater to a slightly higher dial

setting (1/2 division).
