<p>PURPOSE:To permit to stop heat-up during traveling and restart it before returning home even in case of absence in the home by traveling or the like, for example, consume no useless electricity and improve convenience of handling by a method wherein a period, in which hot-water is not used, is preset and whereby the conduction of a heating body is stopped during the period while the conduction of the heating body is restarted when the period is finished. CONSTITUTION:The preset number of days, inputted through a setting switch 6, is indicated in digital on an indicator 7 through a micro-computer 4. On the other hand, the micro-computer 4 outputs a control signal S3 for controlling a relay 9 while the relay 9 receives said control signal S3 and controls the conduction of a heater 2. In this case, the period of stopping conduction of midnight electric power is preset by a setting means (a) whereby the conduction of the heating body (d) is stopped during said period through a control means (c). On the other hand, when the finish of said period of stopping conduction is detected by a finish of period detecting means (b), the conduction of the heating body (d) is started again through said control means (c).</p> |
