An air conditioner has a control-data storage unit to store therein control data, a buffer unit to store therein update data of the control data, a rewriting unit, a data reception unit, and a reception processing unit. The rewriting unit executes a rewriting process of rewriting the control data stored in the control-data storage unit with the update data stored in the buffer unit. The data reception unit receives, through a wireless communication, the update data that is transmitted multiple times from a transmitter. The reception processing unit determines whether the rewriting process is in progress at a time when the update data is received, discards the received update data if the rewriting process is in progress, and stores the received update data in the buffer unit if the rewriting process is not in progress. |
