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-
stat body. Failure to do so may result in
equipment damage and/or personal in-
jury.
OPERATINGYOURTHERMOSTAT
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 straight out from the subbase. To attach
the thermostat body, line up the four terminal
pinsontheuppersectionofthethermostatback
with the matching 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.

for the program to be lost, the thermostat
will automatically return to the factory
programmed temperatures (64°F heating
and82°Fcooling)whenpowerisrestored.
Youmust reprogramthe thermostatif this
happens.
If the word BATTERY is flashing in the

OPERATING FEATURES
Now that you are familiar with the thermostat
displayand buttons, readthe following informa-
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.
This feature is enabled by option switch #3.
To enable the EMR function, you must
move option switch #3 (located on the back
of the thermostat body) to the ON position.
To do this, press
SYSTEM
HEAT - OFF - COOL - AUTO
until OFF is dis-
playedonthethermostat.Removethether-
mostat body from the wall, turn it over, and
checktheposition ofoption switch#3. Ifthe
switchisON(up),simplyputthethermostat
back on the wall and press
SYSTEM
HEAT - OFF - COOL - AUTO
until the
desired operating mode is displayed. If the
switch is OFF (down), use a pencil or small
screwdriver to move the switch to the ON

13
position (see figure below). Remove the
battery for at least two minutes, to allow the
thermostat to reset itself. Replace the bat-
teryandputthethermostatbackonthewall.
Press
SYSTEM
HEAT - OFF - COOL - AUTO
until the desired operating
mode is displayed.
EMR (ON)
Switch #1 set at installation (DO NOT CHANGE)
Switch #2 set at installation (DO NOT CHANGE)
Switch #3 ON
Switch #4 (see TOTAL KEYPAD LOCKOUT)
To disable EMR, press
SYSTEM
HEAT - OFF - COOL - AUTO
untilOFF is
displayed. Remove the thermostat body
from the wall and use a pencil or small
screwdriver to move option switch #3 to the
OFF (down) position. Remove the battery
and allow at least two minutes for the ther-
mostat to reset itself. Replace the battery,
press
SYSTEM
HEAT - OFF - COOL - AUTO
until OFF is displayed, then
replace the thermostat on the wall. Press
SYSTEM
HEAT - OFF - COOL - AUTO
until the desired operating mode is
displayed.
•AUTOMATIC CHANGEOVER — If your
thermostat was configured for this option,
you can set the thermostat to automatically
switchthesystemfromheatingtocoolingas
needed.Press
SYSTEM
HEAT - OFF - COOL - AUTO
tosetthethermostat
toAUTO(thesetpointdisplayisblankinthe
AUTO mode). The system will now auto-
maticallyswitchbetweenheatingandcool-
ing depending on the actual room tem-
perature.

If the thermostat is configured for automatic
changeover, the thermostat will not allow the
temperature separation between the highest
heat setting and the lowest cool setting to be
less that 1°F. For example, if the highest heat
settingis76°F,thelowestcoolsettingcannotbe
below 77°F (see diagram below).
•TWO HOUR TEMPERATURE OVER-
RIDE — Press or until the dis-
play shows the temperature you want. The
thermostat will override current program-
mingand keep theroom temperature atthe
selected temperature for two hours. After
twohours, the thermostat will automatically
revert to the program.
This feature will not work in the AUTO mode.
Therefore, we do not recommend using the
temperature override feature when the thermo-
stat is in the AUTO mode. Pressing or
in the AUTO mode will cause the thermo-
stat to revert to the mode (heat or cool) in which
it was last cycled before switching to the AUTO
mode and will prevent automatic switching for
two hours. If you do press or in the
AUTO mode, you may press
RUN
PRGM
to return to
programmed operation in the AUTO mode.

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
