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 in- formation 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
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- SWITCH 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 8 The Display 1 Continuously displays system mode (HEAT, OFF, COOL, HOLD). During programming, the day of the week is displayed (MON, TUE, WED, 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).

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 . HOLD will be dis- COPY played. Then choose the desired hold tem- perature by pressing thermostat will hold the room temperature at the selected setting until you press 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 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 EVE (evening) 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 5. Press either temperature to your selected HEAT B setting (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.

- 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 31: Questions And Answers
QUESTIONS AND ANSWERS 1. How can I permanently change a part of my program? VIEW Press until you reach the time/ PRGM temperature schedule you want. Then press TIME TIME BACK 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: Your Thermostat
stop programming at this point, press start the normal program function. See PRO- GRAMMING 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: Operating Your Thermostat
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.
