York HIC4008B21S Installation And Maintenance Manual page 44

● The RUN indicator on the wired controller for the indoor unit will flash 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 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.
