Abstract

An air-conditioning control system, which controls a central-type air-conditioning system, includes a plurality of auxiliary controllers set in respective areas of a plurality of areas and a main controller capable of communicating with each auxiliary controller. Each auxiliary controller includes a sound wave receiving unit, which receive sound waves that are outputted from a portable apparatus, and a sound wave strength information transmitting unit which transmits, to the main controller, sound wave strength information indicating sound wave reception strength. B the main controller, when specific sound wave strength information is present among the sound wave strength information received from the auxiliary controllers, a first operating mode is set for the area in which the auxiliary remote controller that is a transmission source of the specific sound wave strength information indicating the highest sound wave strength is set, and a second operating mode is set for all the remaining areas.

Claims
