OPERATINGYOURTHERMOSTAT
Before you begin programming your thermo-
stat,youshouldbefamiliarwithitsfeaturesand
with the display and 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 ther-
mostat body and the subbase.
Use
SYSTEM
HEAT - OFF - COOL - AUTO
to turn thermostat OFF be-
fore removing or attaching the thermo-
statbody.Equipmentdamageand/orper-
sonal injury could occur.
Thesubbaseisattachedtothewall,butyoucan
remove the thermostat body for easy program-
ming. To remove the thermostat body from the
subbase, grasp the thermostat body and gently
pull it out from the bottom of the subbase and
pivot up. To attach the thermostat body, line up
thefourterminalpinsontheuppersectionofthe
thermostatbackwiththematchingconnectoron
the subbase. Insert these, then gently pivot the
thermostat body down to connect the eight pin
connectors on the lower portion of the thermo-
statback.Gentlypushuntilthesnapconnectors
engage.DONOTFORCEORPRYTHETHER-

The Back of The Thermostat Body
Turnthe thermostatbody over.On theback are
the 9 volt Energizer®alkaline battery and the
option switches.
1. The9voltEnergizer®alkalinebatterypro-
vides power to the thermostat when the
24 VACpowerisinterrupted(forexample,
whenyouremovethethermostatfromthe
wallforprogramming).Afreshbatterywill
maintain the stored program for approxi-
matelyaweek.Ifpowerlossislongenough
for the program to be lost, the thermostat
will automatically return to the factory
programmed temperatures (64°F heating
and82°Fcooling)whenpowerisrestored.
Youmust reprogramthethermostatif this
happens.
If the word BATTERY is flashing in the
displaywindow,thebatteryislowandshould
be replaced with a fresh 9 volt Energizer®
alkaline battery. The battery will provide
power for all functions except the display
lightandaudiopromptingbeep,whichwork
only on 24 VAC power.

OPERATING FEATURES
Now that you are familiar with the thermostat
displayand buttons,readthe followinginforma-
tion to learn about the many features of the
thermostat.
•COMPUTED ENERGY MANAGEMENT
RECOVERY (EMR) — The thermostat’s
microcomputerautomaticallycalculatesthe
timeitwilltaketochangethetemperatureto
the next program setting. Then the thermo-
stat will activate the heating or cooling sys-
tem to change the temperature so that the
desired temperature is reached at the be-
ginning of the next program period. As an
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.
•AUTOMATIC CHANGEOVER — You can
set the thermostat to automatically switch
the system from heating to cooling as
needed.Use
SYSTEM
HEAT - OFF - COOL - AUTO
tosetthethermostatto
AUTO (the setpoint display is blank in the
AUTO mode). The system will now auto-
matically switch between heating and cool-
ingdependingon theactual roomtempera-
ture.
The thermostat will not allow the tempera-
ture separation between the highest heat
settingandthelowestcoolsettingtobeless

that 1°F. For example, if the highest heat
setting is 76°F, the lowest 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 tempera-
ture at the selected temperature for two
hours.Aftertwohours,thethermostatwill
automatically revert to the program.
•HOLD TEMPERATURE — Thethermostat
can hold any temperature within its range
for an indefinite period, without reverting to
the program. Press
HOLD
COPY
. HOLD will be
displayed. Then choose the desired hold
temperaturebypressing or .The
thermostat will hold the room temperature
at the selected setting until you press
RUN
PRGM
to start program operation again. This fea-
ture is ideal for energy conservation when
the building is unoccupied for an extended
period of time.
•°F/°C CONVERTIBILITY — Press

at the same time until the tem-
perature display is in °C(Celsius). To

•ADJUSTABLE HEATING AND COOLING
CYCLE TIMES (ANTICIPATION) — If the
heating/coolingsystemisturningonandoff
too often (short cycles) or not often enough
(long cycles), you may want to adjust the
anticipation setting.
A cooling anticipation setting of less
than 10 may cause decreased compres-
sor life.
Toadjust anticipation,press
SET
CLOCK
and
ADV

at the same time. The display will show
HEAT 8 (this is the factory preprogrammed
heating anticipation setting). You may se-
lect any anticipation setting from 4 to 40.
If the heat cycles are too short, press

toincreasethe cycletime.Ifthe heatcycles
are too long, press

to decrease the
cycletime.Tosetcoolinganticipation,press

•LOW BATTERY INDICATOR — The word
BATTERY will flash on the display if the 9
volt alkaline battery is low and should be
replaced.
CAUTION
!

•COMPRESSORSHORTCYCLEPROTEC-
TION — To protect your compressor from
potential damage due to rapid cycling, this
thermostat has a built-in delay of 5 minutes
between cooling cycles. The following may
cause a time delay in COOL:
a) Return of power after a power outage.
b) Pressing
SYSTEM
HEAT - OFF - COOL - AUTO
to change operating
modes.
c) Pressing ,creating acallfor COOL
too soon after a previous call.
•SYSTEM INDICATOR LIGHTS — The red
indicator light comes on when the heating
or cooling system is operating. The yellow
indicator light comes on when the second
or third stages of heating or cooling are
operating.
•AUDIO PROMPTING — Each time you
pressabutton,thethermostatwillbeep(this
feature works only when the thermostat is
attached to the wall and 24 VAC power is
present to the thermostat).
•BACKLIT DISPLAY — When you press
any button on the thermostat, the display is
litforapproximatelyeightseconds(thisfea-
ture works only when the thermostat is
attached to the wall and 24 VAC power is
present to the thermostat).

Switches #1 and #2 are set at installation
andshould notbechanged. Toenabletotal
keypad lockout, move option switch #3 to
ON (ensure that option switch #4 is OFF).
To disable total keypad lockout, move op-
tion switch #3 to OFF.
•PARTIAL KEYPAD LOCKOUT — When
option switch #4 is in the partial keypad
lockout position (ON), programs cannot be
altered. All buttons except and
are disabled. When using those buttons
during partial lockout, the heating tempera-
turecannotberaisedabovetheprogrammed
heating temperature for the current period.
Likewise, the cooling temperature cannot
be lowered below the programmed cooling
temperature for the current period.
•TOTAL KEYPAD LOCKOUT — When op-
tion switch #3 is in the total keypad lockout
position (ON), programs cannot be altered
and all buttons are disabled.

Ifyouwanttochangethepreprogrammedtimes
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 (COOL A and COOL B). Use the
table on the next page to write down the
temperatures you have selected. Keep in
mindthatyoucanprogramupto4tempera-
tures (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).
