Possible causes

(1) There is no voltage between the M-NET transmission line connected to the AE-C/EW-C. (2) The M-NET transmission line connected to the AE-C/EW-C is shorted. (1) Contact failure of the transmission line of an outdoor unit or indoor unit. (2) Attenuation of the transmission voltage/signal because the allowable range for the transmission line wiring has been exceeded. • Farthest end: Exceeds 200 m (656 ft) • Remote controller line: Exceeds 10 m (32 ft) However, there is no problem if the portion where the remote controller line exceeds 10 m (32 ft) is 1.25 mm². (3) Attenuation of the transmission voltage/ signal because mismatch of transmission line types Wire diameter: Less than 1.25 mm² (4) The M-NET power supply is duplex feeding and has a same polarity connection. (5) Failure of control board in the outdoor unit (1) Defective AHC ADAPTER
