PRECAUTIONS
Ifindoubtaboutwhetheryourwiringismillivolt,line,
or low voltage, have it inspected by a qualified
heating and air conditioning contractor, electrician,
orsomeonefamiliarwithbasicelectricityandwiring.
Do not exceed the specification ratings.
All wiring must conform to local and national electri-
cal codes and ordinances.
Thiscontrolisaprecisioninstrument,andshouldbe
handledcarefully.Roughhandlingordistortingcom-
ponents could cause the control to malfunction.
To prevent electrical shock and/or equip-
ment damage, disconnect electric power to
system, at main fuse or circuit breaker box,
until installation is complete.
CAUTION
!
Do not use on circuits exceeding specified
voltage. Highervoltagewilldamagecontrol
and could cause shock or fire hazard.
Do not short out terminals on gas valve or
primary control to test. Short or incorrect
wiring will burn out thermostat and could
cause personal injury and/or property
damage.

SELECT THERMOSTAT LOCATION
Proper location insures that the thermostat will
provide a comfortable building temperature. Ob-
serve the following general rules when selecting
a location:
1. Locate thermostat about 5 ft. above the floor.
2. Installthermostatonapartitioningwall,notonan
outside wall.
3. Never expose thermostat to direct light from
lamps,sun,fireplacesoranytemperatureradiat-
ing equipment.
4. Avoid locations close to windows, adjoining out-
side walls, or doors that lead outside.
5. Avoid locations close to air registers or in the
direct path of air from them.
6. Makesuretherearenopipesorductworkinthat
part of the wall chosen for the thermostat loca-
tion.
7. Never locate thermostat in a room that normally
warmer or cooler than the rest of the building.
8. Avoid locations with poor air circulation, such as
behind doors or in alcoves.
ROUTE WIRES TO LOCATION
All wiring must conform with local and national
electrical codes and ordinances.
NOTE

1. 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(seefig.1).Frombasement,drill3⁄4”hole
in partition floor next to guide hole. In buildings
without basements, drill 1⁄2” hole through ceiling
and into partition from above (see fig. 1).
2. Through this hole drop a light chain, or 6” chain
attachedtoastrongcord.Snagcordinbasement
with hooked wire. In buildings without base-
ments, drop cord through hole in ceiling and
down partitioning; snag cord at the thermostat
location.
3. Attach thermostat wires to cord and pull wires
through hole in wall so that 6” of wire comes out
of the wall.

REPLACEMENT INSTALLATION
REMOVE OLD THERMOSTAT
1. Shutoffelectricityatthemainfuseboxuntil
installation is complete. Verify power is off
with a voltmeter.
2. Remove the front cover of the old thermo-
stat. With wires still attached, remove
wall plate from the wall.
3. If the old thermostat has a wall mounting
plate, remove the thermostat and the wall
mounting plate as an assembly.
4. Usethe CrossReference Guideto findthe
thermostat type you are replacing.
5. Identifyeachwireattachedtotheoldthermo-
stat using the labels enclosed with the new
