Before you begin programming your thermo-
stat,youshouldbefamiliarwithitsfeaturesand
withthedisplayand the location and operation
of the thermostat buttons. The information in
this section will help you become familiar with
your new thermostat so that you can easily
program it.
Your thermostat consists of two parts: the
thermostat body and the subbase.
Use
SYSTEM
SWITCH
to turn thermostat OFF
before removing or attaching the ther-
mostat body. Equipment damage and/
or personal injury could occur.
OPERATING YOUR THERMOSTAT
The subbase is attached to the wall, but you
can remove the thermostat body for easy pro-
gramming. To remove the thermostat body
from the subbase, grasp the thermostat body
and gently pull it out from the bottom of the
subbaseandpivotup.Toattachthethermostat
body,lineupthefourterminalpinsontheupper
section of the thermostat back with the match-
ing connector on the subbase. Insert these,
then gently pivot the thermostat body down to
connect the eight pin connectors on the lower
portion of the thermostat back. Gently push
until the snap connectors engage. DO NOT
FORCE OR PRY THE THERMOSTAT as this
may damage the unit.

1. The 9 volt Energizer®alkaline battery
provides power to the thermostat when
the 24 VAC power is interrupted (for ex-
ample, when you remove the thermostat
from the wall for programming). A fresh
battery will maintain the stored program
forapproximately aweek.Ifpowerlossis
long enough for the program to be lost,
thethermostatwillautomaticallyreturnto
the factory programmed temperatures
(64°F heating and 82°F cooling) when
power is restored. You must reprogram
the thermostat if this happens.

before removing thermostat from the
wall to replace the battery.

2. You may adjust the option switches for
keypad lockout (see OPERATING FEA-
TURES).

The buttons (other than and ) are
located behind the thermostat door. To open
the door, use your fingernail in the indentation
at the top center of the door. Pull the door out,
then swing the door down on its hinges.
Following are brief descriptions of the display
and the thermostat buttons.

OPERATING FEATURES
Now that you are familiar with the thermostat
display and buttons, read the following infor-
mation to learn about the many features of the
thermostat.
•COMPUTED ENERGY MANAGEMENT
RECOVERY (EMR) — The thermostat’s
microcomputerautomaticallycalculatesthe
time it will take to change the temperature
to the next program setting. Then the ther-
mostat will activate the heating or cooling
system to change the temperature so that
the desired temperature is reached at the
beginningofthenextprogramperiod.Asan
example of this feature, assume that you
have programmed your thermostat to pro-
vide an overnight heating temperature of
62°F, and that during the next program
period, beginning at 6:00 AM, you have
programmed a temperature of 70°F. The
thermostat will automatically activate the
heating system at about 5:00 AM, so that
the programmed 70°F temperature is
reached by about 6:00 AM.
•AUTOMATICCHANGEOVER—Youcan
setthethermostattoautomaticallyswitch
the system from heating to cooling as
needed. Use
SYSTEM
SWITCH
to set the thermo-
stat to AUTO (the setpoint display is
blank in the AUTO mode). The system
will now automatically switch between
heating and cooling depending on the
actual room temperature.
The thermostat will not allow the tempera-
ture separation between the highest heat
settingandthelowestcoolsettingtobeless
that 1°F. For example, if the highest heat

13
settingis 76°F, thelowest cool setting can-
not be below 77°F (see diagram below).
•TWO HOUR TEMPERATURE OVER-
RIDE — Press or until the
display shows the temperature you want.
The thermostat will override current pro-
gramming and keep the room temperature
at the selected temperature for two hours.
After two hours, the thermostat will auto-
matically revert to the program.
•HOLDTEMPERATURE—Thethermostat
can hold any temperature within its range
foran indefinite period, without reverting to
the program. Press
HOLD
COPY
. HOLD will be
displayed. Then choose the desired hold
temperature by pressing or .
Thethermostatwillholdtheroomtempera-
ture at the selected setting until you press
RUN
PRGM to start program operation again. This
feature is ideal for energy conservation
when the building is unoccupied for an
extended period of time.
•°F/°CCONVERTIBILITY—Press TIME

display is in °C(Celsius). To display °F,
repeat the process.

•ADJUSTABLEHEATINGANDCOOLING
CYCLE TIMES (ANTICIPATION) — If the
heating/coolingsystemisturningonandoff
toooften (shortcycles)ornotoftenenough
(long cycles), you may want to adjust the
anticipation setting.
A cooling anticipation setting of less
than 10 may cause decreased com-
pressor life.
To adjust anticipation, press SET
CLOCK and
ADV
DAY
at the same time. The display will show
HEAT8(thisisthefactorypreprogrammed
heating anticipation setting). You may se-
lect any anticipation setting from 4 to 40. If
the heat cycles are too short, press TIME
FWD to
increase the cycle time. If the heat cycles
are too long, press
TIME
BACK
to decrease the
cycletime.Tosetcoolinganticipation,press

to return to your program.
•LOW BATTERY INDICATOR —Theword
BATTERY will flash on the display if the 9
volt alkaline battery is low and should be
replaced.
CAUTION
!

15
•AUDIO PROMPTING — Each time you
press a button, the thermostat will beep
(this feature works only when the thermo-
stat is attached to the wall and 24 VAC
power is present to the thermostat).
•BACKLIT DISPLAY — When you press
anybutton onthethermostat,thedisplayis
lit for approximately eight seconds (this
feature works only when the thermostat is
attached to the wall and 24 VAC power is
present to the thermostat).
•COMPRESSOR SHORT CYCLE PRO-
TECTION — To protect your compressor
frompotentialdamageduetorapidcycling,
this thermostat has a built-in delay of 5
minutes between cooling cycles. The fol-
lowing may cause a time delay in COOL:
a)Return of power after a power outage.
b)Pressing
SYSTEM
SWITCH
to change operating
modes.
c)Pressing or , creating a call
for COOL too soon after a previous call.
•SYSTEM INDICATOR LIGHTS —The red
indicatorlightcomesonwhenevertheheat-
ing or cooling system is operating. The
yellow indicator light comes on when the
secondorthirdstagesofheatingorcooling
are operating.

•TOTAL KEYPAD LOCKOUT —Whenop-
tion switch #3 is in the total keypad lockout
position (ON), programs cannot be altered
and all buttons are disabled.
Programming should be completed, desired
system operation should be selected (HEAT,
COOL, or AUTO), and battery should be in-
stalled before changing option switch #3.

This section will help you plan and program
your thermostat to meet your needs.
Formaximumcomfortandefficiency,keepthe
following guidelines in mind when planning
your program.
• When heating (cooling) your building, pro-
gramthetemperaturestobecooler(warmer)
when the building is vacant or during peri-
ods of low activity.
• During early morning hours, the need for
cooling is usually minimal.
PLANNING FOR YOUR NEEDS
First, answer the following questions to help
you decide what your needs are. If you are
PROGRAMMING YOUR THERMOSTAT
usingthethermostatforacommercialapplica-
tion (a store, office building, etc.), answer
questions 1 through 4. If you are using the
thermostat in your home, answer questions 5
through 8.
FOR COMMERCIAL APPLICATIONS:
1a. What time does the first person arrive at
the building in the morning?
b. What temperature should the building be
at this time? (heating? cooling?)
2a. Whattimedothebuildingoccupantsreach
a maximum activity level (using lights,
equipment, meeting rooms, etc.)?
b. What temperature should the building be
at this time?

If you want to change the preprogrammed
times and temperatures, follow these steps.
1. Determine the heating and cooling tem-
peratures you want to use. You may select
up to two heating temperatures (HEAT A
and HEAT B), and up to two cooling tem-
peratures(COOLAandCOOLB).Usethe
following table to write down the tempera-
tures you have selected. Keep in mind that
you can program up to 4 temperatures (2
heating, 2 cooling) at a time.
To operate properly in the AUTO mode, there
must be a minimum 1°F separation between
the highest heat temperature and the lowest
cool temperature (see diagram below).
