this section will help you become familiar with
your new thermostat so that you can easily
program it.

to turn thermostat to OFF
mode before removing or attaching the
thermostat body. Failure to do so may
resultinequipmentdamageand/orper-
sonal injury.
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
andgentlypullitstraightoutfromthesubbase.
To attach the thermostat body, line up the four
terminal pins on the upper section of the ther-
mostat back with the matching connector on
thesubbase.Insertthese,thengentlypivotthe
thermostat body down to connect the eight pin
connectors on the lower portion of the thermo-
stat back. Gently push until the snap connec-
tors engage. DO NOT FORCE OR PRY THE
THERMOSTAT as this may damage the unit.

1. The 9 volt Energizer®alkaline battery pro-
vides power to the thermostat when the
24VAC power is interrupted (for example,
when you remove the thermostat from the
wall for programming) A fresh battery will
maintain the stored program for approxi-
matelyaweek.Ifpowerlossislongenough
for the program to be lost, the thermostat
will automatically return to the factory pro-
grammedtemperatures(64°Fheatingand
82°Fcooling)whenpowerisrestored.You
must reprogram the thermostat if this hap-
pens.
If the word BATTERY is flashing in the
display window, the battery is low and
should be replaced with a fresh 9 volt
Energizer® alkaline battery. The battery
will provide power for all functions except
thedisplaylightandaudiopromptingbeep,
which work only on 24VAC power.

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
beginning of the next program period. As
an example of this feature, assume that
you have programmed your thermostat to
provide 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.
Thisfeatureisenabledbyoptionswitch#3.
To enable the EMR function, you must
moveoptionswitch#3(locatedontheback
ofthethermostatbody)totheONposition.
To do this, press
SYSTEM
SWITCH
until OFF is
displayed on the thermostat. Remove the
thermostat body from the wall, turn it over,
andcheckthepositionofoption switch #3.
If the switch is ON (up), simply put the
thermostat back on the wall and press
SYSTEM
SWITCH
untilthedesiredoperatingmodeis

displayed.Ifthe switchisOFF (down),use
a pencil or small screwdriver to move the
switch to the ON position (see figure be-
low). Remove the battery for at least two
minutes, to allow the thermostat to reset
itself.Replacethebatteryandputthether-
mostat back on the wall. Press
SYSTEM
SWITCH
until the desired operating mode is dis-
played.

and allow at least two minutes for the
thermostat to reset itself. Replace the bat-
tery,press
SYSTEM
SWITCH
untilOFFisdisplayed,
then replace the thermostat on the wall.
Press
SYSTEM
SWITCH
until the desired operating
mode is displayed.
•AUTOMATIC CHANGEOVER — If your
thermostat was configured for this option
at installation, you can set the thermostat
to automatically switch the system from
heating to cooling as needed. Press
SYSTEM
SWITCH tosetthethermostattoAUTO(the
ON
1234

14
setpointdisplayisblankintheAUTOmode).
The system will now automatically switch
between heating and cooling depending
on the actual room temperature.
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
setting is 76°F, the lowest cool setting cannot
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-
grammingandkeeptheroomtemperature
at the selected temperature for two hours.
After two hours, the thermostat will auto-
matically revert to the program.
This feature will not work in the AUTO mode.
Therefore, we do not recommend using the
temperatureoverridefeaturewhenthethermo-
stat is in the AUTO mode. Pressing or

conservation when the building is unoccu-
pied for an extended period of time.

at the same time until the tem-
perature display is in °C(Celsius). To dis-
play °F, repeat the process.
•ADJUSTABLE HEATING AND COOL-
INGCYCLETIMES(ANTICIPATION)—If
the heating/cooling system is turning on
and off too often (short cycles) or not often
enough (long cycles), you may want to
adjust the anticipation setting.
A cooling anticipation setting of less
than10maycausedecreasedcompres-
sor life.

PROGRAMMING YOUR THERMOSTAT
Nowyouarereadytoprogramyourthermostat.
This section will help you plan and program
yourthermostattomeetyourneeds.Formaxi-
mumcomfortandefficiency,keepthefollowing
guidelines in mind when planning your pro-
gram.
• When heating (cooling) your building, pro-
gram the temperatures to be cooler
(warmer) when the building is vacant or
during periods 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.
1a. What time does the first person arrive at
the building in the morning?

19
b. What temperature should the building be
at this time? (heating? cooling?)
2a. What time does the building become va-
cant?
b. What temperature should the building be
at this time?
Now look at the factory preprogrammed times
andtemperaturesshownbelow.Ifthisprogram
willsuityourneeds,simplypress
RUN
PRGM
tobegin
running the factory preset program.
If you want to change the preprogrammed
times and temperatures, do the following.
Determine the heating and cooling times and
temperatures you want to use. Use the follow-
ingtabletoplanyourprogramtimeperiodsand
temperatures.Youmayalsowanttolookatthe
sampleprogramtabletogetanideaofhowthe
thermostat can be programmed. You may se-
lect up to two heating temperatures (HEAT O
for occupied temperature and HEAT U for
unoccupied temperature), and up to two cool-
ing temperatures (COOL O and COOL U).
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.

NOTE: Damper operation is linked to occupied or unoccupied temperature settings, not time periods. If you
program an unoccupied temperature during an occupied time period, the damper will not operate during
that occupied period. We suggest programming occupied temperatures only during occupied time periods,
and unoccupied temperatures during unoccupied time periods.
