CHIGO equipped with a self-diagnosis option. If any malfunction is detected, the air conditioner stops and the error code of the Chigo air conditioner is immediately displayed, which is easy to find in the instructions.
To notify about errors, air conditioners use blinking diodes located on the front of the indoor module. When a breakdown of the air conditioner is detected, the bulbs begin to blink or glow continuously, which is also reflected in the instructions.
