Troubleshooting:
Methods of judging whether ports of master control board are normal: connect a 50k
resistor to the corresponding port to see on the monitor software whether the discharge
temperature or compressor-top temperature is 25°C. If yes, master control board is
normal; if no, replace master control board.
