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.
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.Why is the fan running constantly, regard- less of system operation?
You have programmed the fan to run continu- ously during this program period. To override
the programmed fan, press | FAN | until FAN |
SWITCH |
AUTO is displayed. To change the program- ming, see PROGRAMMING YOUR THER-
MOSTAT.
7.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. However, if there is power to the thermostat and the display is blank or frozen, static discharge is probably the cause.
