Abstract
A device management system includes: an air-conditioning apparatus and a server with a storage, a controller. The storage stores a first identifier unique to the air-conditioning apparatus and a second identifier different from the first identifier and uniquely identifying the air-conditioning apparatus in communication with the server. The controller receives the second identifier and a third identifier changed from the first identifier when the air-conditioning apparatus configuration is changed. The controller detects a change from the first identifier to a third identifier when the second identifier matches the second identifier stored in the storage. The controller converts the third identifier to the first identifier. The server controls operation of the air-conditioning apparatus that sent the third identifier as a replacement or repair of the air-conditioning apparatus.
