Abstract
To provide an air conditioner capable of operating devices in an outdoor unit by connecting an indoor unit, which is capable of transmitting operational commands and operational modes using simple ON/OFF signals to the outdoor unit, even if the indoor unit does not have transmission means for transmitting and receiving information between the outdoor unit, or the indoor unit has transmission means with a different data transmission protocol from the outdoor unit. When it is determined that only ON/OFF signals of operational commands and operation modes have been transmitted, the devices disposed inside the outdoor unit are independently controlled based on the ON/OFF signals.
