Trouble Diagnosis
When the test pin on the outdoor unit control PCB is short-circuited, each part can be operated individually.
• After turning OFF the main unit power, short-circuit the test pin (black), then turn the power back ON.
Output is performed in the sequence shown in the table below, for 0.5 seconds each.
