Page 5: Operating Your Thermostat
OPERATING YOUR THERMOSTAT 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. - Page 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. ® 1. The 9 volt Energizer provides power to the thermostat when the 24 VAC power is interrupted (for ex- ample, when you remove the thermostat from the wall for programming).
- Page 7 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 the display light and audio prompting beep, which work only on 24 VAC power.
- Page 8 The buttons (other than located behind the thermostat door. To open the door, use your fingernail in the indentation at the top center of the door. Pull the door out, then swing the door down on its hinges. Following are brief descriptions of the display and the thermostat buttons.

- Page 12 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 microcomputer automatically calculates the time it will take to change the temperature to the next program setting.
- Page 13 setting is 76 F, the lowest cool setting can- not be below 77 F (see diagram below). COOLING TEMPERATURES DEAD BAND 1 F HEATING TEMPERATURES • TWO HOUR TEMPERATURE OVER- RIDE — Press display shows the temperature you want. The thermostat will override current pro- gramming and keep the room temperature at the selected temperature for two hours.
- Page 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. CAUTION A cooling anticipation setting of less than 10 may cause decreased com- pressor life.
- Page 15 • AUDIO PROMPTING — Each time you press a button, the thermostat will beep (this feature works only when the thermo- stat is attached to the wall and 24 VAC power is present to the thermostat). • BACKLIT DISPLAY — When you press any button on the thermostat, the display is lit for approximately eight seconds (this feature works only when the thermostat is...
- Page 16 • TOTAL KEYPAD LOCKOUT — When op- tion switch #3 is in the total keypad lockout position (ON), programs cannot be altered and all buttons are disabled. NOTE Programming should be completed, desired system operation should be selected (HEAT, COOL, or AUTO), and battery should be in- stalled before changing option switch #3.
- Page 17 Partial Keypad Lockout (ON) 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. To enable partial keypad lockout, move option switch #4 to ON (ensure that option switch #3 is OFF).

Page 18: Programming Your Thermostat
PROGRAMMING YOUR THERMOSTAT 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. •... - Page 19 3a.

- Page 20 Heating Program for ALL days of the Week: PERIOD 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).
- Page 21 Your Temperature Selected Designation Temperature HEAT A HEAT B COOL A COOL B 2. Determine the time periods during which you will program the temperatures you have just selected. You must program 4 periods for each day (periods 1, 2, 3 & 4). However, you may use the same heating and cooling temperatures for consecutive time periods.

Page 24: Entering Your Program
ENTERING YOUR PROGRAM Follow these steps to enter the heating/cooling program you have selected. NOTE We recommend that you remove the thermo- stat from the wall for programming (especially for entering cooling programming). A fresh 9 ® volt Energizer alkaline battery must be in- stalled to perform off-wall programming. - Page 25 5. Press once. The display will show the CLOCK day of the week as an abbreviation (MO for Monday, TU for Tuesday, etc.). 6. Press and hold either TIME reach the current day of the week. 7. Press once. The display will show the PRGM correct time and room temperature alter- nately.
- Page 26 3. Press either temperature to your selected HEAT A setting. 4. Press VIEW once. The letter A will change to TEMP the letter B, representing HEAT B. 5. Press either temperature to your selected HEAT B setting. 6. Press PRGM SYSTEM 7.
- Page 27 cooling period 1 and the currently pro- grammed HEAT A or HEAT B temperature for heating/cooling period 1. EXAMPLE: This display window shows that for Monday’s heating/cooling period 1, the start time is 5:00 AM, and 64 is the programmed temperature (this example reflects factory preprogramming, where 64 is the HEAT A temperature).
- Page 28 7. Repeat steps 3 through 5 to select the start time and heating temperature for Monday’s heating/cooling period 2. 8. Repeat steps 3 through 7 for Monday’s heating/cooling periods 3 and 4. 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.
- Page 29 Program Cooling Temperatures CAUTION 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 property damage may occur due to air conditioner compressor operation in cold weather.
- Page 30 6. Press 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 program operation.
- Page 31 3. Press HOLD once. COPY will be displayed. A COPY number from 1 to 7 will also appear, repre- senting the day you have selected to copy (Monday is 1, Tuesday is 2, Wednesday is 3, etc.). For example, if in step 2 you se- lected to copy Wednesday’s program, when you press HOLD...
- Page 32 4. Press and hold VIEW to view heating/cool- PRGM ing periods and heating temperatures for Tuesday. 5. Repeat steps 3 and 4 to review all remain- ing days’ programming. If you find an error in any day’s programming, go back to the programming instructions to correct the er- ror (you can change any part of your pro- gram while you are reviewing it).
- Page 33 QUESTIONS AND ANSWERS 1. How can I permanently change a part of my program? Press VIEW until you reach the PRGM time/temperature schedule you want. Then press change the program (remember, when you change the time, you are changing it for both the heating and cooling programs).

- Page 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 thermostat.
- Page 37 11. Why doesn’t the temperature change at the time I programmed? There may be a number of causes for this situation. The following are primary rea- sons. • The EMR function is operating. The EMR function will automatically bring on the system automatically to bring the tem- perature to the selected level by the beginning of the next program period.
- Page 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. • The blower delay feature is operating. This energy saving feature continues to blow conditioned air through the ducts after the system has turned off, rather than letting the air dissipate.
