Diagnostic Code (numbers) Notes:
1. Retrying means the controller will try at least one
more cycle before a manual reset is required.
2. A non-blinking code number means the retry
periods have not been successful.
3. Codes may be recalled for review. Recalled codes
that blink indicate that the unit recovered from that
code. If it failed to recover, the code will be on
steady.
