SAFETY FEATURES
Low Battery Warning
■ Your thermostat has a two-stage low battery warning system.
When the batteries are first detected to be weak, the first stage
low battery warning is indicated by battery symbol flashing on
the LCD display. At your earliest convenience, you need to replace
the batteries with 2 new AA alkaline batteries.
■ 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 that new batteries have been inserted, the
thermostat will return to normal operation.
