摘要

A gateway apparatus (103) receives a request frame transmitted from a system controller (101) to an indoor unit 1 (111), and determines whether a sensor specified in the request frame is a sensor 1-A (121) which is connected with the indoor unit 1 (111) or a sensor 1-B (123) which is not connected with the indoor unit 1 (111). When the sensor specified in the request frame is the sensor 1-B (123), the gateway apparatus (103) acquires a measurement value from the sensor 1-B (123), and responds to the system controller (101) with the acquired measurement value of the sensor 1-B (123).
