PROBLEM TO BE SOLVED: To provide an air conditioner system which shortens time required for network topology analysis and avoids a burden on development of a relay and saves cost of the relay.SOLUTION: A management device HOST has a function for transmitting request data to a repeater and terminal equipment (indoor equipment, outdoor equipment) using broadcast communication and executing network topology analysis on the basis of received response data. The request data include: the number of repeater passing stages showing the number of repeaters through which the request data have passed by the time when the request data are received by a repeater or terminal equipment; and a final passage repeater address showing an address of a repeater through which the request data have passed finally. The repeater relays the request data while updating the number of repeater passing stages and the final passage repeater address, whenever relaying the request data. When receiving the request data, the terminal equipment replies to the management device after storing the number of repeater passing stages and the final passage relay address within the received request data in response data. |
