1.8 Troubleshooting with the Indoor Unit LEDs and the Remote Controller
Shutdown For some errors, the system only shuts down when the error occurs several times. This means that
you have to wait until the system shuts down to be able to see the flashing LED on the front panel and
the error code on the remote controller.
