6.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 (Stage 1). If the batteries become too weak for normal operation, the thermostat enters the second battery power shortage mode (Stage 2). When insufficient battery power is left, the battery icon will flash alone on the display and your system will turn off. The display will be blank when no battery power is left. 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.
