2 Centralized control system2. Centralized controller (MCM-A202B)10) Various LED displayAfter power reset to the centralized controller, it carries out indoor unit tracking process through the interface modules.I/M 0Main:0RMC:0Main:1RMC:1Main:2RMC:2I/M 5Main:0RMC:3Main:1RMC:4Main:2RMC:5I/M 7Main:0RMC:6Main:1RMC:7Main:2RMC:81. During tracking interface modules, LED whose number is equivalent to interface module addressinstantaneously flickers. (In LED 00 LED 05 LED 07 order)2. If one of the interface modules does not register all its indoor units, centralized controller also does notcomplete tracking process and continues to flicker its LEDs which are matched to interface moduleaddress (Continuously rotating LED 00 LED 05 LED 07 flickering).(1) Under group mode tracking (K3 to OFF) When there occurred an error in one of the indoor units, RMC-matching LED on the centralized controllerflickers. If communication between them are blocked for some reasons, entire RMC-matching LEDs on thecentralized controller blink at the same time.Under tracking Tracking completed Error in RMC3 indoor unitLED 03 blinkingCommunication blockin interaction with I/Ms All LEDs blinking60
