When a malfunction occurs in the outdoor unit, the LEDs on the circuit
board light to indicate the error. Refer to the following table for the description of each error according to the LEDs.
When the fault is cleared, the LED lamp goes off.
However, for discharge pipe temperature abnormal and high pressure
abnormal, the LED lamp lights continuously for 24 hours, as long as the
power is not turned off.
