SELECTING THERMOSTAT LOCATION  
INSTALLATION  
INSTRUCTIONS  
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.

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.  
W A R N I N G  
Not for use with compressors without time delays.  
Additional adjustments, if necessary, may be made as  
follows:  
BURNER CYCLES TOO LONG - Set adjustable heater to a  
SPECIFICATIONS  
slightly lower dial setting (1/2 division).  
BURNER CYCLES TOO SHORT - Set adjustable heater to a  
slightly higher dial setting (1/2 division).  
24 Volts A.C.  
Electrical Rating: 24 to 30 Volts A.C.  
Heat Anticipator: 0.20 to 1.2 Amp. Max.  
Cool Anticipator: 0 to 1.0 Amp. Max.  
W A R N I N G  
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.
