M (≥1) N (≥0) / Error of the outdoor unit See note 1,2
Note:
1. The outdoor failure can also be indicated by the indoor unit,the checking method as follows:outdoor unit error
code=(M*10+N)-20.LED4 ash M times and LED3 ash N times .
2. LED4 is a yellow one on the indoor main control PCB,LED3 is a green one.
3. To get much more details about the out door unit failure,please refer to the outdoor unit trouble shooting list.
