    • PROBLEM TO BE SOLVED: To simplify the connection state of a remote controller to an interphone by modulating an interphone voice signal by means of a first modulating means so as to transmit it and modulating a remote controller data signal by means of the second modulating means. SOLUTION: A hot water supplier 1 supplies hot water or heats a bath by the control operation of a combustion system and a hot water supply system by a hot water supply control means 7. Data signals transmitted from the first remote controller 10 through a first connecting line and from the second remote controller 40 through the second connecting line 9 are demodulated by a data AM modulating/demodulating means 5 which constitutes the second modulating means 3. The second remote controller 10 remote-controls the hot water supplier 1 through the first connecting means 8, displays the operation state of the hot water supplier 1 and makes a voice call with the second remote controller 40 through the second connecting means 9. A call-transmission FM modulating means 14 modulates the voice signal from a call-transmitting means 21 and transmits carrier wave f1 to a speaker 52. A call-reception FM demodulating means receives carrier wave f2 from the microphone 52 of the second remote controller 40, demodulates it and transmits it to the speaker 22.

    • PURPOSE:To clearly observe the indication of the remote controller and further to reduce power consumption by suitably controlling the brightness of back light. CONSTITUTION:The detected output of a light receiving sensor 3 for detecting the surrounding brightness of a remote controller 30 is inputted to a control part 10, and the detected level is monitored. When the light receiving sensor 3 detects the turning-on starting illuminance of brightness required for turning on the back light, back light 21 is turned on. At such a time, since it is really a little dark state, the indication is gradually hardly observed while getting dark. Therefore, it can be clearly observed by making the back light 21 gradually bright. Accordingly, the back light 21 is controlled so as to be bright until the invert illuminance as illuminance to just invert the state of clearly observing the indication by making the back light bright with the increase of darkness and the state of clearly observing the indication even without making the back light bright and after the inverse illuminance, the brightness of the back light is controlled to be lowered at a certain degree so as not to hardly observe the indication of a display means 22.

    • PURPOSE:To simplify the constitution and prevent a leak of fuel by receiving information on abnormal vibration by respective combustion appliance if the abnormal vibration is detected, and stopping supplying fuel to the respectively appliance once the respective combustion appliances receive the information. CONSTITUTION:There are a water heater 1, a gas heating device 20, a gas range, a gas boiler 40, a microcomputer meter 50, etc., as the combustion appliances. Then the seismoscope 5 of the water heater 1 monitors the detection of abnormal shaking such as an earthquake and sends a signal indicating abnormality to a gas valve control means 4 once detecting the abnormality, and the gas valve control means 4 closes the supply valve of the water heater 1 to stop supplying gas, thereby preventing gas from leaking. Further, a radio transmitting and receiving means 2 sends an abnormality signal in order to let other combustion appliances know that. The respective radio transmitter receivers 22, 32, 42, and 52 of the combustion appliances such as the gas heating device 20, gas range 30, gas bath boiler 40, and microcomputer meter 50 close gas valves on receiving the information on the abnormal shaking.
