Abstract (en)

A remote controller (315, 511), and (517) can restrict the operation and manipulation of a local controller (110, 310, 410, 511, 512), and (517), or the local controller itself can be manipulated so as to restrict operation and manipulation. Accordingly, it is possible to prevent a certain user from manipulating the operation settings of an air conditioner (110, 340), and (540) at his or her own will.
