Air-conditioner remote controller and air-conditioning control system

An air-conditioner remote controller in an air conditioner system that includes the air-conditioner remote controller and an air conditioner that performs air-conditioning control using room temperature information received from the air-conditioner remote controller, the air conditioner system further including a plurality of external temperature sensors placed outside the air-conditioner remote controller and outside the air conditioner and located in an area to be heated or cooled by the air conditioner, and an inlet-port temperature sensor placed at an inlet port of the air conditioner, the air-conditioner remote controller comprising:

• a built-in temperature sensor disposed inside the air-conditioner remote controller to measure a room temperature near the air-conditioner remote controller;
• a storage to store room temperature information that is information on the room temperature measured by the built-in temperature sensor, the plurality of external temperature sensors, and the inlet-port temperature sensor and store schedule information that sets, for each time zone, at least two temperature sensors of the built-in temperature sensor, the external temperature sensors, and the inlet-port temperature sensor to measure a room temperature to be used as room temperature information in the air-conditioning control of the air conditioner;
• and
• a controller to perform control such that the room temperature information from the at least two temperature sensors set by the schedule information is acquired from the storage and the acquired room temperature information is transmitted to the air conditioner in accordance with the schedule information,
• wherein the controller determines whether the acquired room temperature information from at least one of the at least two temperature sensors is within a normal value range so as to use a mean of the room temperature information values from at least one of the at least two temperature sensors within the normal value range and, when the acquired room temperature information in all of the at least two temperature sensors is not within the normal value range, instructs the air conditioner to perform the air-conditioning control using an inlet temperature that is measured by the inlet-port temperature sensor placed at the inlet port of the air conditioner.
