This low voltage thermostat is designed to provide convenient control of the heating/cooling system. To provide
greater room comfort, the sensitive spiral bimetal is combined with an adjustable heating anticipator and a fixed
cooling anticipator to provide maximum comfort.
Low Voltage Heating/Cooling Thermostat
INSTALLATION INSTRUCTIONS
DESCRIPTION
If in doubt about whether your wiring is millivolt, line, or low
voltage, have it inspected by a qualified heating and air
conditioning contractor, electrician, or someone familiar
with basic electricity and wiring.
Do not exceed the specification ratings.
All wiring must conform to local and national electrical
codes and ordinances.
This control is a precision instrument, and should be
handled carefully. Rough handling or distorting components could cause the control to malfunction.

PRECAUTIONS
CAUTION
!
To prevent electrical shock and/or equipment
damage, disconnect electric power to system at
main fuse or circuit breaker box until installation
is complete.
Do not short out terminals on gas valve or primary control to test. Short or incorrect wiring will
burn out heat anticipator and could cause personal injury and/or property damage.
WARNING
!
Do not use on circuits exceeding 30 volts. Higher
voltage will damage control and could cause
shock or fire hazard.

INSTALLATION
SELECT THERMOSTAT LOCATION
Proper location insures that the thermostat will provide a
comfortable home temperature. Observe the following
general rules when selecting a location:
1. Locate thermostat about 5 ft. above the floor.
2. Install thermostat on a partitioning wall, not on an
outside wall.
3. Never expose thermostat to direct light from lamps,
sun, fireplaces or any temperature radiating equipment.

⁄4” guide hole

Approximately
5 feet from floor
4. Avoid locations close to windows, adjoining outside
walls, or doors that lead outside.
5. Avoid locations close to air registers or in the direct
path of air 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 thermostat in a room that is warmer or
cooler than the rest of the home, such as the kitchen.
8. Avoid locations with poor air circulation, such as behind doors or in alcoves.
9. The living or dining room is normally a good location,
provided there is no cooking range or refrigerator on
opposite side of wall.
ROUTE WIRES TO LOCATION
NOTE
All wiring must conform with local and national electrical
codes and ordinances.
1. If an old thermostat being replaced is in a satisfactory
location, and the wiring appears to be in good condition, use existing wiring. If in doubt, re-wire.
2. If a new location is chosen or if this is a new installation,
thermostat wiring must first be run to the location
selected.
3. Probe for obstructions in partition before drilling 1⁄2”
hole in wall at selected location. Take up quarter
round and drill a small guide hole for sighting (see
fig. 1). From basement, drill 3⁄4” hole in partition floor
next to guide hole. In houses without basements, drill
1
⁄2” hole through ceiling and into partition from above
(see fig. 1).

ATTACH SUBBASE TO WALL
CAUTION
!
To prevent electrical shock and/or equipment
damage, disconnect electric power to system at
main fuse or circuit breaker box until installation
is complete.
1. Disconnect electrical power at main fuse or circuit
breaker.
2. Pull wires through opening near center of subbase and
connect wires beneath terminal screws (see figs. 2
and 3 for typical wiring for each application.
3. Push excess wiring into wall and plug hole with fireresistant material (such as fiberglass insulation) to
prevent drafts from affecting thermostat operation.
4. Position subbase over hole in wall and mark mounting
hole locations on wall.
5. Drill mounting holes.
6. Fasten subbase loosely to wall, as shown, using two
mounting screws. Place a level against bottom of
subbase, adjust until level, and then tighten mounting
screws to secure subbase. If holes in wall are too large
and do not allow you to tighten subbase snugly, use
plastic screw anchors to secure subbase.
4. Through this hole drop a light chain, or 6” chain
attached to a strong cord. Snag cord in basement with
hooked wire. In houses without basements, drop cord
through hole in ceiling and down partitioning; snag
cord at the thermostat location.
5. Attach thermostat wires to cord and pull thermostat
wires through hole in wall so that 6” of wire protrudes.
