When the batteries become too weak for normal operation, the
thermostat enters the second stage low battery warning which
shuts down the thermostat. In this condition, “BATT” flashes
alone on the display, and the thermostat will turn your system
Off. Your system will remain shut-off until the batteries are
replaced.
NOTE: The thermostat will still keep the current time and your programs in memory until new batteries are installed. After
confirming new batteries have been inserted, the thermostat will return to normal operation.
NOTE: The backlight will not operate in low battery condition. Replace with 2 new AA alkaline batteries to restore the
Backlight function.
