TROUBLESHOOTING
Error Codes
• The error code function indicates when an operation failure occurs in the system, and provides self-diagnosis about the type of error.
• The error code is displayed on the wired remote controller and the control board LED on the air-source / water-source unit.
• If two or more two errors occur simultaneously, the smallest of the error code numbers is displayed first.
• When the problem causing the error code to appear is fixed, then the error code will immediately stop displaying on the LED.
