Abstract

PURPOSE:To easily let a user detect the abnormal state of a hot water supplier by a method wherein an abnormality alarm switch, which is provided in a remote controller, is operated at the abnormal stoppage of the hot water supplier. CONSTITUTION:When a hot water supplier B stops abnormally for some cause or other, a control circuit means 20 inputs said abnormal state to the abnormality detecting means 28 of a microcomputer 27 in a remote controller 21 so as to judge the detected content of abnormality at the means 28. Abnormality data are once stored after their detection in an abnormality data storing means 29. After the memory retaining time T0 of a storage time setting means 32 or more, the abnormality data in the abnormality data storing means 29 are erased by the judgement of a store release judging means 31. However, when an abnormality alarm switch 25 is operated within the memory retaining time T0 and said input is judged by a switch input judging means 33, the abnormality data in the abnormality data storing means 29 is converted by an abnormality data to audio data converting means 34 to audio data and sent to an audio outputting means 35, which outputs the audio data to a warning means 26 in the form of speech in order to alarm a use of the abnormality.
