<P>PROBLEM TO BE SOLVED: To provide a bath device capable of continuously supplying hot water while minimizing generation of wrong determination of high-temperature abnormality, and surely executing notification and taking measures to maintenance when the maintenance is really necessary. <P>SOLUTION: When a going temperature in a going path at a downstream side of a bath heat exchanger reaches high-temperature abnormality equal to or higher than a determination temperature (YES in SA1) during a hot water supply operation for supplying hot water to a reheating circulation path by opening a hot water supply valve, determination processes are performed by executing a temporal forcible operation of a circulation pump, and reset operation processing for continuously opening and closing the hot water supply valve, while confirming that the number N of times of determination of high temperature does not reach a set number of time α (NO in SA2), to increment N, and then confirming the going temperature of SA1. The hot water supply is forcibly stopped (SA4), when the high temperature abnormality is kept even after the determination processing is executed by the determined number of times. <P>COPYRIGHT: (C)2012,JPO&INPIT |
