● The RUN indicator on the wired controller for the indoor unit flashes orange (0.5 second ON/ 0.5
second OFF), indicative of a fault or error having been generated with activation of protection devices
during the Test Run phase. Alarm code, unit model code, and the number of interconnected indoor units
will be displayed on the LCD as shown below. If the RUN indicator on the wired controller flashes for
2 seconds ON and 2 seconds OFF, the source of the problem could be a failure in the communication
cable between the indoor unit and the wired controller (a loose or severed connection). In this case,

authorized service engineer if the problem cannot be resolved at your end.
