摘要： PURPOSE:To provide a wireless remote control device using an electromagnetic wave in which a performance of an antenna is assured against presence or 4 non-presence of influence of a person. CONSTITUTION:A wireless remote control device is comprised of a hot water feeder 1, a remote controlled transmitting or receiving part 7 for use in transmitting or receiving a control signal using an electromagnetic wave, a remote controlled antenna 6, a remote controlled operating part 10, the first alignment part 11 for getting an impedance alignment between the remote controlled antenna 6 and the remote controlled transmitting or receiving part 7, and the second alignment part 12 connected in place of the first alignment part 11 and having a different alignment value through a changing-over timer 13 and a changing-over switch 14 for a specified period of time after the remote controller is operated. Accordingly, when a person approaches the wireless remote controller in order to perform the operation, the alignment part is changed over so as to assure the transmitting or receiving performance of the remote controller without reducing an efficiency of the antenna.

摘要： PURPOSE:To improve the safety by giving a notice when an elapsed time after reception is interrupted exceeds a prescribed time or displaying the elapsed time so as to allow the user to notify it that the reliability of received information displayed on a receiver is deteriorated timewise. CONSTITUTION:A signal from a device 1 is sent to a receiver 3 via a transmitter 2 and a temperature signal in the signal is displayed on a temperature display means 4. A time measurement means 5, a time comparison means 6, a notice means or a display means 7 are connected to the receiver 3. The remote temperature monitor of the device 1 is formed by the receiver 3, the temperature display means 4, the time measurement means 5, the time comparison means 6, the notice means or the display means 7. The elapsed time when the receiver 3 receives the signal till the current time is measured by the time measurement means 5 and the elapsed time and a preset time are compared by the time comparison means 6 and when a prescribed time is exceeded, the notice means or the display means 7 informs it to the user that a prescribed time is exceeded.

摘要： PURPOSE:To obtain an optimum state for transmission reception with the hot water supply equipment and a remote controller by leading out an antenna from a side face of the hoot water supply equipment in a vertical direction to a pipe leadout direction. CONSTITUTION:In the hot water supply equipment of the remote control system using a radio wave, a hot water supply equipment antenna 3 is led out from a side face 15 of a case 15a of the hot water supply equipment 1 while being insulated from the case 15a and arranged almost perpendicularly to a pipe 10. Through the constitution above, the effect onto the transmission reception efficiency caused by the installation condition specific to the hot water supply equipment equipped with piping of gas and hot water and the environment in a pipe shaft installed by other pipe is avoided and the communication between the hot water supply equipment 1 and the remote controller 2 is ensured.

摘要： PURPOSE:To provide a wireless remote controller operated under an application of electromagnetic wave in which the performance of a remote controller antenna is ensured in response to its mounting location. CONSTITUTION:A wireless remote controller is comprised of a hot water feeding machine 1, a remote transmitter/receiver 7 for transmitting or receiving a control signal under an application of electromagnetic wave, an antenna 6 for a remote controller, a plurality of matching parts 11, 12 having different matching values from each other in order to get impedance matching between this antenna and the remote controlled transmitter/receiver and a changing-over part 13 for selecting one of the plurality of matching parts. Since the selection of the matching parts capable of getting the impedance matching can be easily carried out through the changing-over part 13, a performance of transmitting/ receiving operation in the remote controlled device can be ensured.
