Device control system

A device control system comprising:

• a wireless device including
• a device to be controlled and
• an external connector
• to be connected to the device to be controlled,
• transmit/receive information to/from the device to be controlled, and
• be wirelessly connected to a wireless LAN router;
• a handheld operation terminal to operate the device to be controlled, the handheld operation terminal including a display to display information;
• a wireless operation terminal to operate the device to be controlled via the external connector, the wireless operation terminal being a terminal different from the handheld operation terminal;
• and
• a server to manage the wireless operation terminal that operates the device to be controlled, wherein
• the wireless device selectively transmits first information to the handheld operation terminal when receiving, from the handheld operation terminal, an information acquisition request for the first information that is information necessary for connecting the wireless operation terminal to the external connector,
• the display displays the first information,
• the wireless device selectively transmits second information to the handheld operation terminal when receiving, from the handheld operation terminal, an information acquisition request for the second information that is information to be registered in the server for operating the device to be controlled by the wireless operation terminal,
• the display displays the second information,
• the external connector is switchable between a first connection mode and a second connection mode,
• the first connection mode being a connection mode in which the external connector is wirelessly connected to the wireless operation terminal via the wireless LAN router, and
• the second connection mode being a connection mode in which the external connector is wirelessly connected directly to the wireless operation terminal without via the wireless LAN router, and
• the handheld operation terminal displays the first information or the second information on the display in accordance with the connection mode of the external connector.
