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.

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.

WARNING

Not for use with compressors without time delays.

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).

WARNING

The Adjustable Heater (Heat Anticipator) WILL BURN OUT if 25V
are applied directly to thermostat by shorting out the gas valve or
