Page 6: Parts Of The Thermostat
PARTS OF THE THERMOSTAT The Back of The Thermostat Body Turn the thermostat body over. On the back are the 3 “AA” Energizer ® alkaline batteries. ® The “AA” Energizer alkaline batteries provide power to the thermostat when the 24 VAC power is interrupted (for example, when you remove the thermostat from the wall for programming). - Page 7 CAUTION SYSTEM to turn thermostat OFF be- HEAT - OFF - COOL fore removing thermostat from the wall to replace the batteries. Other than located behind the thermostat door. To open the door, use your fingernail in the indentation at the top of the door to pull it out from the top, then swing it down on its hinges.

Page 12: Operating Features
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. • COMPUTED ENERGY MANAGEMENT RECOVERY (EMR) — The thermostat’s microcomputer can be set to automatically calculate the time it will take to change the temperature to the next program setting. - Page 13 • HOLD TEMPERATURE — The thermostat can hold any temperature within its range for an indefinite period, without reverting to the program. Press HOLD COPY displayed. Then choose the desired hold temperature by pressing thermostat will hold the room temperature at the selected setting until you press to start program operation again.
- Page 14 Whenever adjusting anticipation, increase or decrease the displayed number by only one or two digits, then let the system run for a while to see if the adjustment is sufficient. If the heat cycles are too short, press to increase the cycle time. If the heat cycles are too long, press TIME BACK...

Page 16: Programming Your Thermostat
PROGRAMMING YOUR THERMOSTAT Now you are ready to program your thermostat. This section will help you plan your thermostat’s program to meet your needs. For maximum comfort and efficiency, keep the following guidelines in mind when planning your program. • 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. - Page 17 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? These will be your Period 3 temperature settings. 4a. What time does the building become vacant? b.
- Page 18 Now look at the factory preprogrammed times and temperatures shown at right. If this program will suit your needs, simply press running the factory preset program. If you want to change the preprogrammed times and temperatures, follow these steps. 1. Determine the heating and cooling tempera- tures you want to use.
- Page 19 9:00 AM). Use the table on the following page to plan your program time periods, and the temperatures you want during each period. You may also want to look at the sample program table to get an idea of how the thermostat can be programmed.

Page 22: Entering Your Program
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). Fresh “AA” Ener- ® gizer alkaline batteries must be installed to per- form off-wall programming. - Page 23 7. Press once. The display will show the PRGM correct time and room temperature alter- nately. Select Heating and Cooling Temperatures During programming, if you don’t press any buttons for 5 minutes, the thermostat will enter the HOLD mode and will maintain a constant temperature.
- Page 24 (if you only want to program temperatures for HEAT A and HEAT B, skip to step 7). 6. Repeat steps 4 and 5 to select HEAT C and HEAT D temperature settings, if desired. 7. Press PRGM 8. Press SYSTEM until COOL is displayed.
- Page 25 HEAT A, B, C, or D temperature for heating/ cooling period 1. EXAMPLE: 3. To change the displayed start time to your selected start time for Monday’s period 1, press until your selected time TIME TIME BACK appears. The time will change in 15-minute increments.
- Page 26 NOTE The thermostat has a built-in COPY feature. This feature automatically copies the heating and cooling programs you select for Monday into Tuesday’s through Sunday’s programs. If you want to have the same programming every day, after you program Monday’s schedule, you simply press thermostat’s programmed operation.
- Page 27 Program Cooling Temperatures CAUTION If outside temperature is below 50 F, we recommend that you remove the ther- mostat from the wall before proceeding with the following steps to program cool- ing temperatures. Personal injury and/or property damage could result from air conditioner compressor slugging.
- Page 28 run continuously during this period, press until PRG FAN is displayed. ON - AUTO 5. Repeat step 4 for Monday’s heating cooling periods 3 and 4. 6. Use the HOLD button, or press COPY other days to program. Remember, once you enter Monday’s program, Monday’s pro- gram is automatically copied into Tuesday’s through Sunday’s programs.

2. Press until the day you want to copy from is displayed. If you have not com- pleted programming for this day, do so before proceeding. 3. Press HOLD once. COPY will appear on the COPY display. A number from 1 to 7 will also be displayed, representing the day you have selected to copy from (Monday is 1, Tues- day is 2, etc.). - Page 30 3. Press once to advance to Tuesday. 4. Press and hold to view heating/cooling VIEW PRGM periods and heating temperatures for Tues- day. 5. Repeat steps 3 and 4 to review all remaining days’ programming. If you find an error in any day’s programming, go back to the program- ming instructions to correct the error.

Page 31: Questions And Answers
QUESTIONS AND ANSWERS 1. How can I permanently change a part of my program? Press until you reach the VIEW PRGM time/temperature schedule you want. Then press TIME TIME BACK change the program. See PROGRAMMING YOUR THERMOSTAT. 2. How can I have no change in tempera- ture from one time period to another? Simply select the same temperature for each consecutive time period. - Page 32 press to start the normal program PRGM function. See PROGRAMMING YOUR THERMOSTAT. 4. What happens if the electricity goes off or is manually shut off? If you have not installed 3 “AA” alkaline batteries, the display will go blank and the program will be lost in approximately one minute.
- Page 33 and the display is blank or frozen, static discharge is probably the cause. During periods of low humidity (especially during cold weather), you may feel or see a spark discharge when you touch the ther- mostat. This may cause the program to be lost or the thermostat to display incorrectly.
- Page 34 8. The thermostat beeps every few min- utes. What does this mean? The thermostat will beep every five minutes when the batteries are low and need replac- ing. To override the beeping, press any button on the keypad. The beeping will stop for 15 hours, then start again.
- Page 35 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.
- Page 36 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 PRO- GRAMMING YOUR THERMOSTAT. • 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.
- Page 37 15. I live in an area where daylight savings time is observed. How do I change the thermostat clock twice a year without affecting thermostat programming? To change your clock, follow the instruc- tions for setting current time and day. See ENTERING YOUR PROGRAM.
