LCD Status Messages
The system's control panel LCD provides status messages to signify when the system is operating correctly or when the system needs attention. The LCD lights blue to indicate a normal operating condition and lights amber to indicate an error condition. The LCD scrolls a message that includes a status code followed by descriptive text.
