Outdoor Unit
The outdoor unit has a green LED (LED A) and red LEDs (LED 1 ~ LED 5) on the PCB.
When the microcomputer works in order, the LED A blinks, and when the system is in normal
condition, the red LEDs are OFF.
Even after the error is canceled and the unit operates in normal condition, the LED indication
remains.
