The transmission speed is determined by the indoor and outdoor controllers (8), (12). That is, one data may be sent every half cycle at the time of transmission, or time-divided data may be sent during the half cycle in which transmission is possible. Furthermore, there is no particular limitation on the means for synchronizing transmission and reception. That is, synchronization may be achieved by transmitting signals for starting transmission / reception to each other, or a circuit for generating a synchronization signal from a power supply waveform may be added separately. Further, timers may be provided inside the indoor and outdoor controllers (8) and (12).
