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 temperature 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 maintained for about one year with no 24vAC power present to the thermostat. See OPERATING YOUR THERMOSTAT.

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