<p>PROBLEM TO BE SOLVED: To provide a hot water supply system capable of informing about all failure contents in time series without discriminating apparatus such as hot water supply body and various terminal apparatus from each other. SOLUTION: The system comprises an indicator 16 with light emitting diodes 17 for giving various information, a microcomputer 11 for detecting failures of a hot water supply body 1 and terminal units 2, an EEPROM 15 for storing the contents of failures detected by the computer 11, and a microcomputer 12 for informing the indicator 16 and the light emitting diodes 17 of the contents of failures stored in the EEPROM 15, in the ascending or descending order of the time points of failures detected by the computer 11 according to operation of an operator, whichever the body 1 or the terminal unit 2 fails.</p> |
