34 4. 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 temperatu[...]

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. Wait about two minutes, then reconnect the batte[...]

36 9. 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.

37 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. The following are primary reasons. • The EMR f[...]

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). To change anticipation settings, see OPERAT-[...]
