    QUESTIONS AND ANSWERS How can I permanently change a part of my program? VIEW Press PRGM time/temperature schedule you want. Then TIME TIME press BACK change the program. See PROGRAMMING YOUR THERMOSTAT. How can I have no change in temperature from one time period to another? Simply select the same temperature for each consecutive time period.
  • Page 34 What happens if the electricity goes off or is manually shut off? If you have not installed 3 "AA" alkaline batter- ies, the display will go blank and the program will be lost in approximately one minute. When electricity is restored, the clock will reset itself to 12:00 PM (noon) and the thermostat will maintain a heating temperature of 64 F and a cooling temperature of 82 F until you reenter...
  • Page 35 During periods of low humidity (especially during cold weather), you may feel or see a spark discharge when you touch the thermo- stat. This may cause the program to be lost or the thermostat to display incorrectly. To cor- rect this, remove the thermostat from the wall and disconnect the battery.
  • Page 36 The display is flashing BATTERY. What does this mean? The "AA" batteries installed in the thermostat are low and should be replaced with fresh "AA" ® Energizer alkaline batteries. See OPERAT- ING YOUR THERMOSTAT. 10. The thermostat beeps every few minutes. What does this mean? The thermostat will beep every five minutes when the batteries are low and need replac-...
  • Page 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. 13. Why doesn’t the temperature change at the time I programmed? There may be a number of causes for this situation.
  • Page 38 • 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. 15. Why is the system turning on and off so frequently (seldom)? The anticipation setting is too low (high).
  • Page 39 18. Do I have to reprogram my thermostat after I change the batteries? When the thermostat is on the wall and the system has power, the thermostat is being powered by a 24v AC source. If power is lost, or if the thermostat is removed from the wall, the program will be retained for approximately one minute if there are no batteries installed or if the installed batteries are dead.
