1. An air-conditioning control system for controlling a central-type air-conditioning system capable of performing conditioning in a first operating mode and conditioning in a second operating mode having lower energy consumption than the first operating mode, for each of a plurality of areas of which at least a portion of boundaries is partitioned by an object, the air-conditioning control system comprising:

  • a plurality of auxiliary controllers that are set in respective areas of the plurality of areas; and

    a main controller that is capable of communicating with each of the plurality of auxiliary controllers;

    each of the plurality of auxiliary controllers comprising;

    a sound wave receiving unit that receives sound waves that are outputted from a portable apparatus that is capable of outputting sound waves;

    a sound wave strength information transmitting unit that transmits sound wave strength information to the main controller, the sound wave strength information indicating sound wave reception strength; and

    a processor that receives a time synchronization command transmitted from the main controller and sets a time of a clock so as to be synchronized among the plurality of auxiliary controllers, based on the time synchronization command,the main controller comprising;

    a storage unit that stores therein a predetermined threshold;

    an operating mode setting unit that sets the first operating mode for at least a single area in which each of the auxiliary controllers that is a transmission source for specific sound wave strength information indicating a sound wave strength that is the threshold or higher is located, and sets the second operating mode for at least one of any remaining areas; and

    a processor that transmits the time synchronization command to each of the plurality of auxiliary controllers.
