PURPOSE:To enable to heat or cool a space to be air-conditioned comfortable and with high controllability, by executing remote control of an air-conditioning apparatus by electric waves by detecting the room temperature by a room- temperature detecting circuit and changing a secondary battery by a solar battery. CONSTITUTION:A room-temperature detecting circuit 2 includes, for instance, a thermistor and applies a room-temperature representing signal to a processing circuit 4. Further, a signal for controlling an air conditioning apparatus 7 is produced. In response to a control signal produced by the processing circuit 4, a transmitter circuit 5 produces an electric-wave signal of a high-frequency carrier wave modulated by the control signal produced by the processing circuit 4. A secondary battery 8 for supplying current is disposed in a casing 1 and it is charged by a solar battery 9 disposed on the outside of the casing 1. The opening of a flow control valve 12 of the air-conditioning apparatus 7 is controlled by applying the output signal of a receiver circuit 10. |
