10-2-4. Diagnostic Procedure for Each Check Code (Indoor Unit) Check code [E01 error] Is inter-unit cable of A and B normal? YES NO Correct inter-unit cable of remote controller Is there no disconnection or contact error of connector on harness from terminal block of indoor unit? NO YES Correct connection of connector. Check circuit wiring. NO Is group control operation? YES Is power of all indoor units turned on? YES NO Check power connection of indoor unit. (Turn on power again.) Is power supplied to remote controller? AB terminal: Approx. DC18V YES NO Check indoor P.C. board (MCC-1570). Defect → Replace Are 2 remote controllers set without master unit? NO YES Correct a master unit/a follower unit. (Remote controller address connector) Check remote controller P.C. board. Defect → Replace [E09 error] Are 2 master units set in 2 remote controllers? NO YES Correct as a master unit and a follower unit. Check remote controller P.C. board. Defect → Replace – 99 –
