OUTDOOR UNIT ELECTRONIC BOARDS
To check the parameters on the refrigerant side (PCB-2 board). The digital display will show the present compressor frequency (‘0’ will display if the unit is off or error
code will display if error occurs). Long press the check button and the digital display will show the operating mode, and then press the check button in sequence. The
digital display will show the value, the implication of the value is shown in the diagram below:
