5. Fasten thermostat base loosely to wall using two mounting
screws (see fig. 2). Place a level against bottom of base,
adjust until level, and then tighten mounting screws to secure
base (leveling is for appearance only and will not affect
thermostat operation). If holes in wall are too large and do not
allow you to tighten base snugly, use plastic screw anchors
to secure base.
Take care when securing and routing wires so they do
not short to adjacent terminals or rear of thermostat.
Shorted wires may result in personal injury and/or
property damage.

INSTALLATION
SELECT THERMOSTAT LOCATION
Proper location insures that the thermostat will provide a com-
fortable 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. 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 oppo-
site side of wall.
ROUTE WIRES TO LOCATION
1. If an old thermostat is being replaced and 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 wire must first be run to the location selected. All
wiring must conform with local and national electrical codes
and ordinances.
3. Probe for obstructions in partition before drilling

in wall at selected location. Take up quarter round and
drill a small guide hole for sighting (see fig. 1). From
basement, drill

” hole in partition floor next to guide hole.
In houses without basements, drill

” 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 wire to cord and pull wire through hole in
wall so that 6” of wire protrudes.
ATTACH THERMOSTAT BASE TO WALL
1. Remove thermostat cover. Pull wires through opening near
center of thermostat base and connect wires under terminal
screws (see WIRE THERMOSTAT TO SYSTEM).
2. Push excess wire into wall and plug up hole with fire-resistant
material, such as fiberglass insulation, to prevent drafts from
affecting thermostat operation.
3. Place thermostat base over hole in wall for wires and mark
mounting hole locations on wall.
4. Drill mounting holes.
