Controller fails. It is necessary to read the
fault code value according to the light
flashing.
The fault code consists of two digits.
The fixed order is: first red then yellow.
The flashing of a red light represents the
number of digits.
The flashing yellow light represents the
specific value of the corresponding digit
number.
When the red light flashes once, it means
that the corresponding code digit is ten
digits, and when it flashes twice, it means
the unit digit. For example, the red light
flashes once and the yellow light flashes
three times.

yellow light flashes once, indicating that the
units digit value is 1.
