Read This Before Installing Thermostat (continued)
POWER FAILURE
7
Whenever the main power is interrupted or fails, the
battery power retains the programs and current time.
AUTO RECOVERY
8
Your thermostat is set from the factory to gradually recover
the room temperature from an energy saving program to
your comfort program. Therefore, the thermostat may turn
your system on several minutes prior to your programmed
time. This operation is normal, but can be turned off. Refer to
the Selector Switches information on pages 14-15.
BATTERY WARNING
9
Fresh alkaline batteries should provide over one year of
service. However, when the batteries become drained,
“BATT” will alternate on the display with the current time.
When this message occurs, install 2 new AA batteries. You
have approximately 1 minute to change the batteries and
keep thermostat’s clock and program settings. Once the
batteries have become too low to ensure proper operation,
your system will be turned Off, and the display will be
cleared except for “BATT” flashing on the LCD display.
CAUTION: Once the “BATT” only display occurs, the
thermostat is shut down, and your system will no longer
operate. In this condition, there is no temperature control of
your dwelling.
NOTE: The INDIGLO
®
night-light will not function when the
thermostat is in low battery condition.
NOTE: If you plan to be away from the premises over 30
days, we recommend that you replace the old batteries with
new alkaline batteries prior to leaving.
