Air-conditioner communication system, method of confirming connection of air-conditioner communication system, wireless LAN adapter, and connection confirmation instructions of air-conditioner communication system

A method of confirming a connection between a wireless local area network (LAN) adapter and a terminal device of an air-conditioner communication system included in a ceiling- type air conditioner, wherein the wireless LAN adapter functions as a network communication unit of the air conditioner and the terminal device includes a display, the method comprising:

• accessing the wireless LAN adapter from the terminal device, wherein the wireless LAN adapter is installed at a location where an indicator lamp of the wireless LAN adapter is hidden from view of a user;
• acquiring, from the wireless LAN adapter, connection information that indicates whether the wireless LAN adapter is in communication with a router that configures a LAN;
• and
• indicating in one screen on the display based on the connection information, whether the air conditioner, the wireless LAN adapter, the router, and a server are in communication with one another by using icons that respectively represent the air conditioner, the wireless LAN adapter, the router, and the server and that are aligned in an order of the air conditioner, the wireless LAN adapter, the router, and the server.

A wireless local area network (LAN) adapter that functions as a network communication unit of a ceiling-embedded air conditioner and that communicates with a terminal device, the wireless LAN adapter comprising:

• a central processing unit (CPU) that:
• acquires connection information indicating whether the wireless LAN adapter is in communication with a router that configures a LAN;
• and
• uses the connection information as display image data, wherein
• the display image data indicates whether the air conditioner, the wireless LAN adapter, the router, and a server are in communication with one another via a telecommunication line by using icons that respectively represent the air conditioner, the wireless LAN adapter, the router, and the server and that are aligned in an order of the air conditioner, the wireless LAN adapter, the router, and the server in one screen, wherein
• the wireless LAN adapter is installed at a location where an indicator lamp of the wireless LAN adapter is hidden from view of a user.
