OPERATING YOUR THERMOSTAT
The subbase is attached to the wall, but you canremove the thermostat body for easy program-ming. To remove the thermostat body from thesubbase, grasp the thermostat body and gentlypull it out from the bottom of the subbase andpivot up. To attach the thermostat body, line upthe four terminal pins on the upper section of thethermostat back with the matching connector onthe subbase. Insert these, then gently pivot thethermostat body down to connect the nine pinconnectors on the lower portion of the thermo-stat back. Gently push until the snap connectorsengage. DO NOT FORCE OR PRY THE THER-MOSTAT as this may damage the unit.
Before you begin programming your thermo-stat, you should be familiar with its features andwith the display and the location and operationof the thermostat buttons. The information inthis section will help you become familiar withyour new thermostat so that you can easilyprogram it.
Your thermostat consists of two parts: the ther-mostat body and the subbase .
Use SYSTEMSWITCH to turn thermostat to OFF
mode before removing or attaching thethermostat body. Equipment damageand/or personal injury could occur.
CAUTION!

OPERATING FEATURES
Now that you are familiar with the thermostatdisplay and buttons, read the following informa-tion to learn about the many features of thethermostat.
• COMPUTED ENERGY MANAGEMENTRECOVERY (EMR) — The thermostat’smicrocomputer automatically calculates thetime it will take to change the temperature tothe next program setting. Then the thermo-stat will activate the heating or cooling sys-tem to change the temperature so that thedesired temperature is reached at the be-ginning of the next program period. As anexample of this feature, assume that youhave programmed your thermostat to pro-vide an overnight heating temperature of
62°F, and that during the next programperiod, beginning at 6:00 AM, you haveprogrammed a temperature of 70°F. Thethermostat will automatically activate theheating system at about 5:00 AM, so thatthe programmed 70°F temperature isreached by about 6:00 AM.This feature is enabled by option switch #3.To enable the EMR function, you mustmove option switch #3 (located on the backof the thermostat body) to the ON position.
To do this, press SYSTEMSWITCH until OFF is dis-
played. Remove the thermostat body fromthe wall, turn it over, and check the positionof option switch #3. If the switch is ON (up),simply put the thermostat back on the wall
and press SYSTEMSWITCH until the desired operat-
ing mode is displayed. If the switch is OFF

screwdriver to move option switch #3 to theOFF (down) position. Put the thermostat
back on the wall and press SYSTEMSWITCH until the
desired operating mode is displayed.• AUTOMATIC CHANGEOVER — You can
set the thermostat to automatically switchthe system from heating to cooling asneeded. To set the thermostat for automaticchangeover after programming, press
SYSTEMSWITCH to set the thermostat to AUTO (the
setpoint temperature display is blank in theAUTO mode). The system will now auto-matically switch between heating and cool-ing, depending on the actual room tempera-ture.
In the AUTO mode, the thermostat will notallow the temperature separation between

the highest heat setting and the lowest coolsetting to be less than 1°F. For example, ifthe highest heat setting is 76°F, the lowestcool setting cannot be below 77°F (seediagram below).
• TWO HOUR TEMPERATURE OVER-RIDE — Press or until thedisplay shows the temperature you want.The thermostat will override current pro-gramming and keep the room temperatureat the selected temperature for two hours.After two hours, the thermostat will auto-matically revert to the program.
We do not recommend using the temperatureoverride feature when the thermostat is in theAUTO mode. If you press or in theAUTO mode, the thermostat will revert to themode (heat or cool) in which it last cycled and willprevent automatic switching for two hours. If youdo press or in the AUTO mode, you
may press RUNPRGM to return to programmed opera-
tion in the AUTO mode.
• HOLD TEMPERATURE — The thermostatcan hold any temperature within its rangefor an indefinite period, without reverting to
the program. Press HOLDCOPY . HLD will be dis-
played. Then choose the desired hold tem-perature by pressing or . The
NOTE
15
thermostat will hold the room temperature
at the selected setting until you press RUNPRGM
to start program operation again. This fea-ture is ideal for energy conservation whenthe building is unoccupied for an extendedperiod of time.
• °F/°C CONVERTIBILITY — Press TIMEFWD and
TIMEBACK at the same time until the temperature
display is in °C (Celsius). To display °F,repeat the process.
• ADJUSTABLE HEATING AND COOLINGCYCLE TIMES (ANTICIPATION) — If theheating/cooling system is turning on and offtoo often (short cycles) or not often enough(long cycles), you may want to adjust theanticipation setting.
A cooling anticipation setting of lessthan 10 may cause decreased compres-sor life.
To adjust heat anticipation, press SETCLOCK and
ADVDAY at the same time. The display will show
HEAT 18 (this is the factory preprogrammedheating anticipation setting). You may se-lect any anticipation setting from 4 to 40(note that for add-on heat pump sys-tems, a minimum anticipation setting of10 is recommended ). Whenever adjustinganticipation, increase or decrease the dis-played number by only one or two digits,then let the system run for a while to see ifthe adjustment is sufficient. If the heat cycles

16
are too short, press TIMEFWD to increase the
cycle time. If the heat cycles are too long,
press TIMEBACK to decrease the cycle time. To
set cooling anticipation, press SETCLOCK and
ADVDAY at the same time again. The display will
show COOL 14 (factory preprogrammed
cooling anticipation). Use the TIMEFWD and TIME
BACK
buttons to adjust anticipation. Press RUNPRGM to
return to your program.• LOW BATTERY INDICATOR — The word
BATTERY will flash on the display if the 9volt alkaline battery is low and should bereplaced.
• AUDIO PROMPTING — Each time youpress a button, the thermostat will beep (thisfeature works only when the thermostat isattached to the wall and 24VAC power ispresent to the thermostat).
• BACKLIT DISPLAY — When you pressany button on the thermostat, the display islit for approximately eight seconds (this fea-ture works only when the thermostat isattached to the wall and 24VAC power ispresent to the thermostat).
• SYSTEM INDICATOR LIGHTS — The fourlights on the upper right part of the thermo-stat indicate system operation (see PARTSOF THE THERMOSTAT).
• COMPRESSOR SHORT CYCLE PROTEC-TION — To protect your compressor frompotential damage due to rapid cycling, thisthermostat has a built-in delay of 5 minutes
17
between heat pump heating and coolingcycles. The following may cause a timedelay in COOL:
a) Return of power after a power outage.
b) Pressing SYSTEMSWITCH to change operating
modes.c) Pressing or , creating a call
for HEAT or COOL too soon after aprevious call.
• TOTAL KEYPAD LOCKOUT — When op-tion switch #4 is in the total keypad lockoutposition (ON), programs cannot be alteredand all buttons are disabled.

Now you are ready to program your thermostat.This section will help you plan your thermostat'sprogram to meet your needs.
For maximum comfort and efficiency, keep thefollowing guidelines in mind when planning yourprogram.
• When heating (cooling) your building, pro-gram the temperatures to be cooler (warmer)when the building is vacant or during peri-ods of low activity.
• During early morning hours, the need forcooling is usually minimal.
PLANNING FOR YOUR NEEDS
First, answer the following questions to help youdecide what your needs are.
1a. What time does the first person arrive at thebuilding in the morning?
b. What temperature should the building be atthis time? (heating? cooling?)
2a. What time does the building become va-cant?
b. What temperature should the building be atthis time?
PROGRAMMING YOUR THERMOSTAT
20
Now look at the factory preprogrammed timesand temperatures shown below. If this program
will suit your needs, simply press RUNPRGM to begin
running the factory preset program.
If you want to change the preprogrammed timesand temperatures, determine the heating andcooling times and temperatures you want touse. Use the following table to plan your pro-
gram time periods and temperatures. You mayalso want to look at the sample program table toget an idea of how the thermostat can be pro-grammed. You will select two heating tempera-tures (HEAT O for occupied temperature andHEAT U for unoccupied temperature) and twocooling temperatures (COOL O and COOL U).
To operate properly in the AUTO mode, thehighest heat temperature cannot be the sameas or higher than the lowest cool temperature (orvice versa); see diagram below.

1. How can I permanently change a part ofmy program?
Press VIEWPRGM and ADV
DAY until you reach the
time/temperature schedule you want. Then
press or and TIMEFWD and TIME
BACK to
change the program. See PROGRAMMINGYOUR THERMOSTAT.
2. How can I finish my programming if thedisplay has already changed to time/temperature?During programming, if no buttons arepressed for five minutes, the thermostat willenter the HOLD mode and maintain a con-stant temperature. The display will change
to the time/temperature mode. To resume
programming, press VIEWPRGM until you return to
the point where you stopped programming.Then you may continue to program thethermostat normally. If you want to stop
programming at this point, press RUNPRGM to
start the normal program function. See PRO-GRAMMING YOUR THERMOSTAT .
3. What happens if the electricity goes offor is manually shut off?If you have not installed a 9 volt alkalinebattery, the display will go blank and theprogram will be lost in five seconds. Whenelectricity is restored, the thermostat willmaintain a heating temperature of 64°F and

a cooling temperature of 82°F until youreenter your program. Setpoint tempera-ture will not be displayed.
If a fresh 9 volt Energizer® alkaline battery isinstalled, the program will be maintained forabout one week with no 24VAC powerpresent to the thermostat. See OPERAT-ING YOUR THERMOSTAT.
4. Why can’t I program the thermostat inthe AUTO mode?The thermostat can only be programmed inthe HEAT and COOL modes. See PRO-GRAMMING YOUR THERMOSTAT .
5. What can cause the thermostat displayto freeze or go blank?A completely blank display may indicatethat power has been lost to the thermostatand the backup battery is also dead. How-
ever, if there is power to the thermostat andthe display is blank or frozen, static dis-charge is probably the cause.
During periods of low humidity (especiallyduring cold weather), you may feel or see aspark discharge when you touch the ther-mostat. This may cause the program to belost or the thermostat to display incorrectly.To correct this, remove the thermostat fromthe wall and remove the battery for at leasttwo minutes. After reinstalling the battery,the thermostat will revert to the factory pre-set program until you reprogram the ther-mostat. If you don’t want to reprogram the
thermostat immediately, press SYSTEMSWITCH un-
til OFF is displayed and replace the thermo-
stat on the wall. Then press RUNPRGM to begin
the factory preset program.

To prevent further static discharge prob-lems, touch another object to release staticbuild-up before touching the thermostat.See OPERATING YOUR THERMOSTAT .
6. Why won’t the setpoint temperature goto the temperature I want?In the AUTO mode, the highest heatingsetpoint temperature you select cannot bethe same as or higher than the lowest cool-ing setpoint temperature you select (forexample, if 70°F is your lowest selectedcooling temperature, you cannot select aheating temperature any higher than 69°F).If such a conflict exists, set the lowest cool-ing temperature higher in order to set theheating temperature higher. To set a lowercooling temperature, you must select a lowerheating temperature. See PROGRAMMINGYOUR THERMOSTAT.
7. Why doesn’t the display light come onwhen I press a button? Why don’t I heara beep when I press a button?The display light and audio prompting (beep)only work when the thermostat is on the walland 24VAC power is present to the thermo-stat. See OPERATING YOUR THERMO-STAT.
8. The display is flashing BATTERY. Whatdoes this mean?The 9 volt battery installed in the thermostatis low and should be replaced with a fresh 9volt Energizer® alkaline battery. See OPER-ATING YOUR THERMOSTAT .
9. Why won’t the system turn on, eventhough the thermostat display is func-tioning normally?Either the compressor lockout feature is inoperation or the thermostat is not currently
37
calling for heat or cool. If the compressorlockout is active, the PUMP LED will flash.Wait about 5 minutes for the compressorlockout to expire. If the system is still notrunning, read the cautionary statement be-low. Then, if conditions permit , use or to move the temperature above orbelow the setpoint temperature. See OP-ERATING YOUR THERMOSTAT .
If the outside temperature is below 50 °F,DO NOT use the button to move thetemperature below the setpoint tempera-ture. Property damage may result fromcompressor operation during coldweather.
10. Why doesn’t the temperature change atthe time I programmed?There are a number of causes for this situ-ation. The following are primary reasons.
• The EMR function is operating. The EMRfunction will automatically turn on thesystem early enough to bring the tem-perature to the selected level by thebeginning of the next program period.See OPERATING YOUR THERMO-STAT.
• You have programmed the incorrect dayor time. Check your programming (besure that the times you programmed arecorrect AM or PM times). See PRO-GRAMMING YOUR THERMOSTAT .
• The thermostat is in the HOLD mode.
Press RUNPRGM to start program operation.
CAUTION!
38
See OPERATING YOUR THERMO-STAT.
• If the PUMP LED is flashing, the com-pressor lockout feature is operating; waitabout 5 minutes for system to beginrunning. See OPERATING YOURTHERMOSTAT.
11. Why does the blower fan keep runningafter the system has turned off?The blower delay feature is operating. Thisenergy saving feature continues to blowconditioned air through the ducts after thesystem has turned off, rather than letting theair dissipate.
12. Why is the system turning on and off sofrequently (seldom)?The anticipation setting is too low (high). To
change anticipation settings, see OPER-ATING YOUR THERMOSTAT .
13. Between heating and cooling seasons, Iwant to turn my system off. Can I do thiswithout affecting my thermostat pro-gramming?Any time you wish to turn your system off,
press SYSTEMSWITCH until the display shows OFF.
This will not affect your thermostat's pro-gramming in any way. To turn the system
back on, press SYSTEMSWITCH until HEAT, COOL,
etc. is displayed. The system will automati-cally begin operating according to the cur-rent thermostat program, unless the ther-
39
mostat is in the HOLD mode. See OPER-ATING YOUR THERMOSTAT .
14. I live in an area where daylight savingstime is observed. How do I change thethermostat clock twice a year withoutaffecting thermostat programming?To change your clock, follow the instruc-tions for setting current time and day. SeeENTERING YOUR PROGRAM. Thermo-stat programming is not affected when youchange the clock.
15. Do I have to reprogram my thermostatafter I change the battery?When the thermostat is on the wall and thesystem has power, the thermostat is beingpowered by a 24VAC source. If power islost, or if the thermostat is removed from thewall, the program will be retained for ap-proximately one minute if there is no bat-
tery installed or if the installed battery isdead. If you are changing the battery afterseeing a flashing BATTERY on the display,the installed battery may be dead. If youremove the old battery and install a freshone within one minute, you may not loseyour thermostat programming. After install-ing a new battery, follow the procedures inCHECK YOUR PROGRAMMING to deter-mine whether your programming was main-tained. If the thermostat maintains program-
ming, press SYSTEMSWITCH until OFF is displayed,
put the thermostat back on the wall, pressSYSTEM
SWITCH to select the operating mode you
want, then press RUNPRGM to start program
operation. If programming is lost, you mustreprogram the thermostat. See PROGRAM-MING YOUR THERMOSTAT.
