PURPOSE:To enable setting of an optimum working state, by providing three control systems: a system, employing a phototransmission system and joined in a cordless transmission state, a system joined in an optical fiber transmission state, and a direct system. CONSTITUTION:A second photodetector 56 of a second reception part 42 and a second emission part 22 of a remote controller 6 are coupled to each other through two different remote control systems: a first remote control system from which an optical fiber 30 is removed and which transmits a control signal in a cordless state and a second remote control system, approximately directly connected through the optical fiber 30 and transmitting a control signal. Further, a direct control system is added, and finally an air conditioner is provided with three different working state control systems in all. Either of the three systems can be arbitrarily and freely selected through mounting and demounting of the optical fiber 30 and mounting and demounting of a remote controller 6 to and from an air conditioner body 1. |
