A communication adapter acquires, upon receiving a screen acquisition request from a terminal device via a network, screen data of a requested screen, and transmits the acquired screen data to the terminal device. At this time, the communication adapter identifies at least one next screen that can follow the requested screen, with reference to screen transition data. The communication adapter then acquires screen data of the specified next screen from an air-conditioning controller via a serial cable, and stores the acquired data. |
