PURPOSE:To facilitate decision of quality of equipment upon installation trial running or trouble repairing as well as an inspection upon delivery at factory by providing an indicator, indicating a time from starting of conduction of midnight electric power to starting of conduction of an exothermal body. CONSTITUTION:When the conduction of midnight electric power is started, water temperature Tw, detected by a water temperature sensor 3, is taken into a micro-computer 11 through a water temperature detecting circuit 7 and a hot- water set temperature Ts, detected by a temperature regulating volume 6, is taken into the micro-computer 11 through a hot-water set temperature detecting circuit 8, thereafter, necessary conduction time Hs and conduction starting shift time HP are operated in an operator 11b. Next, the signal of a test port 14 is checked and when it is ''L'', the signal of a remaining hot-water sensor 4 is taken into the micro-computer 11 through a remaining hot-water detecting circuit 9 and the result of it is outputted to an indication circuit 13 to lighten or put off a remaining hot-water indicator 5. On the other hand, in case the signal of the test port 14 is ''H'', the conduction starting shift time HP, operated previously, is outputted into the indication circuit 13 and it is indicated in the remaining hot- water indicator 5.

。According to this embodiment, the energization start shift time (HP) is displayed by operating the test port 14 of the microcomputer 11, so if this function is used, the water temperature sensor can be 3. Temperature control volume 6
It is easy to determine whether the signals are correctly captured and calculated. By changing the temperature control volume 6 or giving a pseudo signal to the water temperature sensor 3, the change in the energization start shift time (HP) can also be used for fault diagnosis. . Furthermore, the energization start shift time (HP) is a time during which energization of the heater 2 is shifted to the latter half of the late night power period, and heat radiation loss is reduced by that time. Therefore, if the configuration is such that the customer can also switch the test port 14 using a switch or the like, the customer can know the energy-saving effect of the device, which has the effect of improving satisfaction with the device.
