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 24 VAC power present to the thermostat. See OP-

ERATING YOUR THERMOSTAT.

5.Why can’t I program the thermostat in the AUTO mode?

The thermostat can only be programmed in the HEAT and COOL modes. See PRO-

GRAMMING YOUR THERMOSTAT.

6.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.
