3. Low battery warning – indicates two stages of
battery power shortage.
When the batteries are detected as weak, the
icon will flash until new AA alkaline batteries are
installed. If the batteries become too weak for
normal operation, the thermostat enters the second
battery power shortage mode.
When no battery power is left, the battery icon will
flash alone on the display and your system will turn
off. The system will remain off until new batteries are
installed.
(Your programs and time settings will be lost if the
batteries are not replaced within one minute.)
The thermostat will resume normal operation after
new batteries are installed.
