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. When electricity is restored, the clock will reset itself to 12:00 PM (noon) and

the thermostat will maintain a heating tem- perature of 64°F and a cooling temperature of 82°F until you reenter your program. Setpoint temperature will not be displayed.

If fresh "AA" Energizer® alkaline batteries are installed, the program will be main- tained for about one year with no 24vAC power present to the thermostat. See OP-

ERATING YOUR THERMOSTAT.

5.What can cause the thermostat display to freeze or go blank?

A completely blank display may indicate that power has been lost to the thermostat and the backup battery is also dead. How- ever, if there is power to the thermostat and the display is blank or frozen, static dis- charge 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. To correct this, remove the thermostat from the wall and disconnect the battery. Wait about one minute, then reconnect the bat- tery. The thermostat will revert to the factory preset program until you reprogram the thermostat. If you don’t want to reprogram
