DESCRIPTION
This thermostat is designed to control a heat pump
systemwhereautomaticchangeoverisnotrequired.The
thermostat is equipped with EMER HEAT and AUX
indicator lights. The EMER HEAT indicator light can be
wired to a malfunction switch in the system to provide a
malfunction indicator.

PRECAUTIONS
If in doubt about whether your wiring is millivolt, line, or
low voltage, have it inspected by a qualified heating and
airconditioningcontractor,electrician,orsomeonefamil-
iar 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 compo-
nents 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 use on circuits exceeding 30 volts. Higher
voltagewilldamagecontrolandcouldcauseshock
or fire hazard.
DO NOT USE this thermostat on heat pump sys-
tems that have a spark ignition gas or fossil fuel
second stage heat source.

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.
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 ap-
pearance only and will not affect thermostat opera-
tion).Ifholes inwallare toolarge anddonot allowyou
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
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 equip-
ment.
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 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.
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
goodcondition,useexistingwiring.Ifindoubt,re-wire.
2. Ifanewlocationischosenorifthisisanewinstallation,
thermostat wire must first be run to the location se-
lected. 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).Frombasement,drill3⁄4” holein partitionfloor
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
attachedto astrongcord.Snagcordinbasementwith
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. Removethermostatcover.Pullwiresthroughopening
near center of thermostat base and connect wires
underterminalscrews(seeWIRE THERMOSTATTO

WIRE THERMOSTAT TO SYSTEM
For best electrical connection, use solid 18 gauge wire. If
you must use stranded wire, tin the wires with solder to
insure a good electrical connection.
1. Strip wires back 1⁄4”.
2. Usingneedle-nosepliers,insertwireintocorrecttermi-
nal block opening (see figs. 3 and 4).
3. Tighten terminal block connector screw.
4. Repeat steps 2 and 3 for each wire.
Someapplicationsmayrequirethatthefanbedisabledin

To prevent electrical shock and/or equipment
damage, disconnect electrical power to system,

OPERATION
This thermostat is easy to operate. The above table
shows how the system will operate when the FAN and
SYSTEM switches are in different positions.
To set the switches, open the door on the left side of the
thermostat (see fig 6). Move the FAN and SYSTEM
switches up or down to select desired system operation.
To set the temperature, move the temperature selection
knob(ontherightside ofthethermostat)untilthe desired
temperature is shown in the window.
ANTICIPATION ADJUSTMENT
The anticipation setting on this thermostat is adjustable.
Any anticipation setting (including the factory setting) will
workwithanysystemforwhichthisthermostatisintended
foruse.However,theusermaybemorecomfortablewith
a particular setting. If the system is turning on and off too
often (short cycles) or not often enough (long cycles) for
the user’s comfort, follow these steps to adjust the antici-
pation.
1. Turn off power to the thermostat.
2. Remove the thermostat cover.
3. Findtheanticipation adjustmentswitches(see fig.3).
4. Usingapencilorsmallscrewdriver,movetheswitches
to the desired setting (see figs. 7 and 8).
5. Carefully snap the cover onto the thermostat base.
6. Turn on power to the thermostat.

This thermostat has a built-in short term (5-minute)
timedelay.Duringthis5-minuteperiod,thethermostat
