5 OPERA TING YOUR THERMOST A T Before you begin programming your thermo- stat, you should be familiar with its features and 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.
6 PARTS OF THE THERMOSTAT The Back of The Thermostat Body Turn the thermostat body over. On the back are the 9 volt Energizer ® alkaline battery and the option switches.
7 BACK OF THERMOSTAT BODY Option switches 9-pin connector 4-pin connector Battery The buttons (other than and ) are located behind the thermostat door. To open the door, pull the door out from the top, then swing the door down on its hinges. Following are brief descriptions of the display and the thermostat buttons.
8 The Display 1 Continuously displays system mode ( HEAT , OFF , COOL , AUTO , HOLD ). During pro- gramming, the day of the week is displayed ( MO , TU , WE , etc). 2 Alternately displays room temperature ( F denotes degrees Fahrenheit and C denotes degrees Celsius) and time of day ( A de- notes AM time and P denotes PM time).

12 OPERATING FEATURES Now that you are familiar with the thermostat display and buttons, read the following informa- tion to learn about the many features of the thermostat.
13 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.
14 • ADJUSTABLE HEATING AND COOLING CYCLE TIMES (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 than 10 may cause decreased compres- sor life.
15 • COMPRESSOR SHORT CYCLE PROTEC- 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.
16 Switches #1 and #2 are set at installation and should not be changed. To enable total keypad lockout, move option switch #3 to ON (ensure that option switch #4 is OFF ).
17 Programming should be completed and battery should be installed before changing option switch #4. Partial Keypad Lockout Switch #1 set at installation ( DO NOT CHANGE ) Switch #2 set at installation ( DO NOT CHANGE ) Switch #3 OFF Switch #4 ON Switches #1 and #2 are set at installation and should not be changed.
18 Now you are ready to program your thermostat. This section will help you plan and program your thermostat to meet your needs. For maximum comfort and efficiency, keep the following guidelines in mind when planning your program.
19 b. What temperature should the building be at this time? 3a. What time do the building occupants reach a minimum activity level (limited personnel in building)? b. What temperature should the building be at this time? 4a. What time does the building become va- cant? b.
20 If you want to change the preprogrammed times 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 ).
21 select 5:00 AM to begin heating period 1 on Monday, then your cooling period 1 for Monday will also begin at 5:00 AM). How- ever, you may choose different time periods for each day separately (for example, heat- ing/cooling period 1 on Monday may begin at 5:00 AM, but heating/cooling period 1 on Saturday may begin at 9:00 AM).

24 ENTERING YOUR PROGRAM Follow these steps to enter the heating/cooling program you have selected. We recommend that you remove the thermostat from the wall for programming (especially for entering cooling programming). A fresh 9 volt Energizer ® alkaline battery must be installed to perform off-wall programming.
25 5. Press SET CLOCK once. The display will show the day of the week as an abbreviation ( MO for Monday, TU for Tuesday, etc.). 6. Press and hold either TIME FWD or TIME BACK until you reach the current day of the week. 7. Press RUN PRGM once. The display will show the correct time and room temperature alter- nately.
26 4. Press VIEW PRGM once. The letter A will change to the letter B , representing HEAT B . 5. Press either or to change the temperature to your selected HEAT B setting. 6. Press RUN PRGM . 7. Press SYSTEM HEAT - OFF - COOL - AUTO until COOL is displayed.
27 display will alternate between the HEAT A and HEAT B temperatures you previously selected). 5. If you want the fan to run continuously during Monday heating/cooling period 1, press FAN ON - AUTO until PRG FAN is displayed. 6. After selecting the desired heating tempera- ture for heating/cooling Monday’s period 1, press VIEW PRGM .
28 NOTE The thermostat has a built-in COPY feature. This feature automatically copies the heating and cooling programs you select for Monday into Tuesday through Sunday’s programs.
29 Program Cooling Temperatures If outside temperature is below 50 ° F, we recommend that you remove the thermo- stat from the wall before proceeding with the following steps to program cooling temperatures. Personal injury or prop- erty damage may occur due to air condi- tioner compressor slugging.
30 6. Press ADV DAY to choose other days to pro- gram. Remember, once you enter Monday’s program, Monday’s program is automati- cally copied into Tuesday’s through Sunday’s programs. 7. After you enter or copy heating and cooling programs for all 7 days, press RUN PRGM to begin program operation.
31 CHECK YOUR PROGRAMMING Follow these steps to check your thermostat programming one final time before beginning thermostat operation. 1. Press SYSTEM HEAT - OFF - COOL - AUTO until HEAT is displayed. 2. Press and hold VIEW PRGM to view the heating/ cooling period times and heating tempera- tures for Monday.
32 programming instructions to correct the er- ror (you can change any part of your pro- gram while you are reviewing it). 6. Press RUN PRGM . 7. Press SYSTEM HEAT - OFF - COOL - AUTO until COOL is displayed. 8. Repeat steps 2 through 5 to check cooling temperatures.
33 which means the temperature will not change from COOL A when period 2 begins. See PROGRAMMING YOUR THERMOSTAT . 3. How can I finish my programming if the display has already changed to time/ temperature? During programming, if no buttons are pressed for five minutes, the thermostat will enter the HOLD mode and maintain a con- stant temperature.
34 press RUN PRGM to start the normal program function. See PROGRAMMING YOUR THERMOSTAT . 4. What happens if the electricity goes off or is manually shut off? If you have not installed a 9 volt alkaline battery, the display will go blank and the program will be lost in five seconds.
35 7. Why won’t the setpoint temperature go to the temperature I want? The highest heating setpoint temperature you select must be at least 1 ° F lower than the lowest cooling setpoint temperature you select (for example, if 70 ° F is your lowest selected cooling temperature, you cannot select a heating temperature any higher than 69 ° F).
36 8. Why doesn’t the display light come on when I press a button? Why don’t I hear a beep when I press a button? The display light and audio prompting (beep) only work when the thermostat is on the wall and 24 VAC power is present to the thermo- stat.
37 CAUTION ! If the outside temperature is below 50 ° F, DO NOT use the button to move the temperature below the setpoint tempera- ture. Property damage may result due to compressor slugging. 11. Why doesn’t the temperature change at the time I programmed? There may be a number of causes for this situation.
38 12. Why does the blower fan keep running after the system has turned off? • You have programmed the fan to run continuously during this period. See PROGRAMMING YOUR THERMO- STAT .
39 15. I live in an area where daylight savings time is observed. How do I change my thermostat clock twice a year without affecting programming? To change your clock, follow the instruc- tions for setting current time and day. See ENTERING YOUR PROGRAM .
