● 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
is displayed on the LCD as shown below. If the RUN indicator on the wired controller flashes for two
seconds ON and two 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,
verify Section 9.3 “Alarm Code” and perform the appropriate troubleshooting measures. Consult with an
authorized service engineer, if the problem cannot be resolved at your end.
