If you hold down both fan speed controls at once, the display will show you the fault codes. Then you can scroll threw with the fan speed controls

Don't scroll -- that's take you to the various input modes. Just hit the "auto" button when it shows zero. The display will show the stored codes. You can scroll at this pooint to see the various stored codes.
