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 eight 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: thethermostat body and the subbase .
Remove power from the system at thecircuit breaker/fuse box before remov-ing or attaching the thermostat body.Equipment damage and/or personal in-jury could occur.

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.
• AUTOMATIC CHANGEOVER — You canset the thermostat to automatically switchthe system from heating to cooling asneeded. First you must move option switch#4 (located on the back of the thermostatbody) to the ON position, if it has not alreadybeen done. To do this, turn off 24v ACpower to the thermostat. Then remove thethermostat body from the wall. Check theposition of switch #4 (the last switch on theright). If it is ON (up), simply put the thermo-stat back on the wall and restore 24v ACpower. If the switch is OFF (down), remove

In the AUTO mode, the thermostat will notallow the temperature separation betweenthe highest heat setting and the lowest coolsetting to be less than 1°F. For example, ifthe highest heat setting is 75°F, the lowestcool setting cannot be below 77°F (seediagram below).
the battery, then use a pencil or small screw-driver to move the switch to the ON position(see figure at right). Leave the battery out ofthe thermostat for at least two minutes , toallow the thermostat to reset itself. DO NOTMOVE OPTION SWITCHES #1 OR #2, asthis may affect thermostat operation. [Op-tion switch #3 enables/disables keypad lock-out (see TOTAL KEYPAD LOCKOUT )].Replace the battery, reprogram the thermo-stat, if necessary, put the thermostat backon the wall, and restore 24v AC power. Toset the thermostat for automatic changeover
after programming, press SYSTEMSWITCH to set the
thermostat to AUTO (the setpoint tempera-ture display is blank in the AUTO mode).The system will now automatically switchbetween heating and cooling, depending onthe actual room temperature.

• 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.
• HOLD TEMPERATURE — The thermostatcan hold any temperature within its rangefor an indefinite period, without reverting to
the program. Press HOLDCOPY . HOLD will be
displayed. Then choose the desired holdtemperature by pressing or .The thermostat will hold the room tempera-ture at the selected setting until you press
RUNPRGM to start program operation again. This
feature 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.
CAUTION!
15
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
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. To set auxil-
iary heat anticipation, press SETCLOCK and ADV
DAY
at the same time again. The display willshow AUX 8 (factory preprogrammed cool-
ing 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
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.
• COMPRESSOR LONG TERM CYCLEPROTECTION — If your system begins tooperate too soon after an extended poweroutage, the compressor may be damageddue to crankcase oil temperature change.This thermostat has a built-in time delay ofone hour less than the length of the powerloss (up to 12 hours). When power is re-
17
stored to the system, heaters in the systemwill begin to heat the crankcase oils. Thethermostat's time delay will lock out thecompressor to prevent its operation until thecompressor oil is sufficiently warmed. Dur-ing the lockout time period, the auxiliaryheating system will operate to maintain asetpoint temperature.For example, if a power outage of threehours occurs, the compressor will be lockedout for two hours.
• TOTAL KEYPAD LOCKOUT — When op-tion switch #3 is in the total keypad lockoutposition (ON), programs cannot be alteredand all buttons are disabled.
Programming should be completed and bat-tery should be installed before changing op-tion switch #3.

PROGRAMMING YOUR THERMOSTAT
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. If you are using thethermostat for a commercial application (a store,office building, etc.), answer questions 1 through4. 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?)
19
2a. What time do the building occupants reacha maximum activity level (using lights, equip-ment, meeting rooms, etc.)?
b. What temperature should the building be atthis time?
3a. What time do the building occupants reacha minimum activity level (limited personnelin building)?
b. What temperature should the building be atthis time?
4a. What time does the building become vacant?b. What temperature should the building be at
this time?
IN YOUR HOME:5a. What time does the first person get up in the
morning?b. What temperature should the house be at
this time?
6a. What time does the last person leave thehouse in the morning?
b. What temperature should the house be atthis time?
7a. What time does the first person arrive homein the evening?
b. What temperature should the house be atthis time?
8a. What time does the last person go to bed atnight?
b. What temperature should the house be atthis time?
Now look at the factory preprogrammed timesand temperatures shown on the following page.If this program will suit your needs, simply press
RUNPRGM to begin running the factory preset pro-
gram.
20
If you want to change the preprogrammed timesand temperatures, follow these steps.
1. Determine the heating and cooling tem-peratures you want to use. You may selectup to four heating temperatures (HEAT A ,HEAT B , HEAT C, and HEAT D), and up tofour cooling temperatures (COOL A , COOLB, COOL C, COOL D). Use the table at theright to write down the temperatures youhave selected.

To operate properly in the AUTO mode, theremust be a minimum 1 °F separation betweenthe highest heat temperature and the lowestcool temperature (see diagram below).
2. Determine the time periods during whichyou will program the temperatures you havejust selected. You must program 4 periodsfor each day (periods 1, 2, 3 & 4). However,you may use the same heating and coolingtemperatures for consecutive time periods.
Also keep in mind that, for any given day,you can only program one set of times forboth heating and cooling (for example, if youselect 5:00 AM to begin heating period 1 onMonday, then your cooling period 1 forMonday will also begin at 5:00 AM). How-ever, you may choose different time periodsfor each day separately (for example, heat-ing/cooling period 1 on Monday may beginat 5:00 AM, but heating/cooling period 1 onSaturday may begin at 9:00 AM). Use thefollowing table to plan your program timeperiods, and the temperatures you wantduring each period. You may also want tolook at the sample program table to get anidea of how the thermostat can be pro-grammed.

QUESTIONS AND ANSWERS
1. How can I permanently change a part ofmy program?
Press VIEWPRGM until you reach the time/tem-
perature schedule you want. Then press
or and TIMEFWD and TIME
BACK to change
the program (remember, when you changethe time, you are changing it for both theheating and cooling programs). See PRO-GRAMMING YOUR THERMOSTAT .
2. How can I have no change in tempera-ture from one time period to another?Simply select the same temperature foreach consecutive time period. For example,you may select the same COOL A tempera-ture for period 2 as you did for period 1,
which means the temperature will not changefrom COOL A when period 2 begins. SeePROGRAMMING YOUR THERMOSTAT .
3. 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 changeto 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
34
programming at this point, press RUNPRGM to
start the normal program function. See PRO-GRAMMING YOUR THERMOSTAT .
4. 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 anda 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.
5. 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 .
6. 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 from
35
the 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 .
7. Why won’t the setpoint temperature goto the temperature I want?In the AUTO mode, the highest heatingsetpoint temperature you select must be at
least 1°F lower than the lowest coolingsetpoint temperature you select (for ex-ample, if 70°F is your lowest selected cool-ing temperature, you cannot select a heat-ing temperature any higher than 68°F). Ifsuch a conflict exists, set the lowest coolingtemperature higher in order to set the heat-ing temperature higher. To set a lower cool-ing temperature, you must select a lowerheating temperature. See PROGRAMMINGYOUR THERMOSTAT.
8. 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.
36
9. 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 .
10. 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 currentlycalling for heat or cool. Wait about 5 minutesfor the compressor lockout to expire. If thesystem is still not running, read the caution-ary statement at the right. Then, if condi-tions permit , use the or buttonsto move the temperature above or below thesetpoint temperature. See OPERATINGYOUR 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 due tocompressor slugging.
11. 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 THERMOSTAT.
CAUTION!
37
• 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. See
OPERATING YOUR THERMOSTAT .• The compressor lockout feature is oper-
ating; wait about 5 minutes for system tobegin running. See OPERATING YOURTHERMOSTAT.
12. 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.
13. Why is the system turning on and off sofrequently (seldom)?The anticipation setting is too low (high). Tochange anticipation settings, see OPER-ATING YOUR THERMOSTAT .
14. 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-
38
mostat is in the HOLD mode. See OPER-ATING YOUR THERMOSTAT .
15. 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.
16. 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 24v AC 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.
