Heat Anticipator: 0.20 to 1.2 Amp. Max.
Cool Anticipator: 0 to 1.0 Amp. Max.

SELECTING THE DEVICE 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:

Locate it about 5 ft. above the floor with a free flow of air.
Install it on a partitioning wall, not on an outside wall.
Never expose it to direct light or radiation from lamps, sun, fireplaces, etc.
Avoid locations close to doors that lead outside, windows, or adjoining outside walls.
Avoid locations close to radiators, warm air registers, or in the direct path of heat from them.
Make sure there are no pipes or duct work in that part of the wall chosen for the thermostat location.
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.
The living or dining room is normally a good location, provided there is no cooking range or refrigerator on opposite side of wall.

INSTALLATION

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.
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.
Again place level on top of thermostat base to be sure itis 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).

The Adjustable Heater (Heat Anticipator) WILL BURN OUT if 25V are applied directly to thermostat by shorting out the gas valve or primary control during testing or by incorrect wiring.
