すなわち、異常発生箇所と、この異常によって危険が
及ぶ範囲を判別し、異常が発生した機能と、危険が及ぶ
範囲の機能だけを停止させるようにしている。That is, the location where the abnormality has occurred and the range in which the abnormality is dangerous are determined, and only the function in which the abnormality has occurred and the function in the area in which the risk is caused are stopped.
縮退運転の一例として、給湯用温度センサ（７）が異
常な値を出力した場合を例にとり説明する。As an example of the degenerate operation, a case where the hot water supply temperature sensor (7) outputs an abnormal value will be described as an example.
