Air-conditioning system

Abstract

A remote controller and an air-conditioning apparatus are provided. The remote controller includes an operation unit, a human detection sensor, a transmission/reception unit, and a processor. The human detection sensor detects the presence or absence of a person, and generates a presence/absence detection signal representing a result of detection of the presence or absence of a person. The processor transmits a schedule operation signal and the presence/absence detection signal to the air-conditioning apparatus. The air-conditioning apparatus includes a heat-source-side control section that controls the operation of the air-conditioning apparatus based on the schedule operation signal and the presence/absence detection signal.
