programming at this point, press PRGM to

GRAMMING YOUR THERMOSTAT.
4.What happens if the electricity goes off or is manually shut off?
If you have not installed a 9 volt alkaline battery, the display will go blank and the program will be lost in five seconds. When
electricity is restored, the thermostat will maintain a heating temperature of 64°F and a cooling temperature of 82°F until you reenter your program. Setpoint tempera- ture will not be displayed.
If a fresh 9 volt Energizer® alkaline battery is installed, the program will be maintained for about one week with no 24 VAC power present to the thermostat. See OPERAT-
ING 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.
