SELECT THERMOSTAT LOCATION
Proper location insures that the thermostat will provide a
comfortable home temperature. Observe the following
general rules when selecting a location:
Stout cord with 6”
5 feet from floor
1. Locate thermostat about 5 ft. above the floor.
⁄ ” guide hole
2. Install thermostat on a partitioning wall, not on an
3. Never expose thermostat to direct light from lamps,
sun, fireplaces or any temperature radiating equip-
4. Avoid locations close to windows, adjoining outside
walls, or doors that lead outside.

Hooked wire for snagging chain
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.
ATTACH SUBBASE TO WALL
7. Never locate thermostat in a room that is warmer or
cooler than the rest of the home, such as the kitchen.
To prevent electrical shock and/or equipment
damage, disconnect electric power to system at
main fuse or circuit breaker box until installation
8. Avoid locations with poor air circulation, such as be-
hind 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.
1. Disconnect electrical power at main fuse or circuit
connect wires beneath terminal screws (see figs. 2
and 3 for typical wiring for each application.
ROUTE WIRES TO LOCATION
3. Push excess wiring into wall and plug hole with fire-
resistant material (such as fiberglass insulation) to
prevent drafts from affecting thermostat operation.
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 condi-
tion, use existing wiring. If in doubt, re-wire.
4. Position subbase over hole in wall and mark mounting
hole locations on wall.
5. Drill mounting holes.
thermostat wiring must first be run to the location
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.
3. Probe for obstructions in partition before drilling ⁄
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⁄
” hole in partition floor
next to guide hole. In houses without basements, drill
⁄2” hole through ceiling and into partition from above
(see fig. 1).
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.
