Abstract
System recognition is performed on devices connected to an identical system without recognizing a device of a different system as a device of the identical system in high-frequency communication. In a device network system, an outdoor unit selected from among all outdoor units of a first network performs a recognition process on the outdoor units and indoor units of the first network. In the first network, communication between individual devices including the outdoor units and the indoor units is performed by using a high frequency, and the recognition process performed by the selected outdoor unit uses a recognition signal having a low frequency.
