1. An air conditioning system comprising:
a communication device including
an electricity generator to generate electricity by receiving light;
a wireless transmitter to receive a supply of the electricity generated by the electricity generator and to transmit communication data wirelessly; and
a communication controller configured to control the transmitter to transmit the communication data on a periodic basis, and
an air conditioner including
an air-conditioner main body to perform air conditioning; and
an operation controller to control the air-conditioner main body, and configured to
determine, while an operation state of the air-conditioner main body is in a stop, whether the communication data is not transmitted for a predetermined transmission time by the wireless transmitter indicating that light is not being received by the electricity generator of the communication device, and
responsive to determining that the communication data is not transmitted in the stop, cause the operation state to be in a setback, the setback being a state in which the air conditioning is performed by the air-conditioner main body so that a temperature in a space where the air conditioner is placed does not exceed a predetermined limit temperature, the stop being a state in which the air conditioning is not performed by the air-conditioner main body.
