Operator: Save these instructions for future use!

FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY
BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE
PERSONAL INJURY AND/OR PROPERTY DAMAGE.

This thermostat and subbase combination is designed to
control a heat pump system where automatic changeover
is not required. However, manual changeover of the
reversing valve can be controlled by the wiring selection
on the subbase and the switching of the SYSTEM switch
to COOL or HEAT (see fig. 2).

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.

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.

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. 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.

ATTACH SUBBASE TO WALL

1. Pull wires through opening near center of subbase
and connect wires under terminal screws (see figs. 2
& 3).

2. Push excess wire into wall and plug up hole with fire­resistant material, such as fiberglass insulation, to
prevent drafts from affecting thermostat operation.

3. Place subbase over hole in wall for wires and mark
mounting hole locations on wall.

4. Drill mounting holes.

5. 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.

6. Check anticipator setting and adjust, if required (see

OPERATION & MAINTENANCE).

Care must be taken 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.

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, re­wire.

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 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).

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.
