PROBLEM TO BE SOLVED: To provide an air conditioner capable of enhancing safety of operation control and security by HA by recognizing an external control device performing HA control and restricting intentional operation control. SOLUTION: This air conditioner is provided with an HA terminal 3, a control means 2 for performing operation control by an HA signal, and a determination means 4 for determining permission of control from the HA terminal; and HA operation control is possible for the first time after the determination means 4 detects a permission signal permitting HA control. Thus, the control device is restricted by the HA terminal. COPYRIGHT: (C)2006,JPO&NCIPI |
