PURPOSE:To appropriately inform the operator of the period of time necessary for maintenance by providing the titled device with a function to control the temperature of a part to be heated in addition to a function to count the number of times of starting and stopping the combustion apparatus, and indicate the counted number of times. CONSTITUTION:The CPU12 counts V1 and V2 ON signals each time these signals are generated, and when the present number of times indicating mode is selected by the manipulation of a push button 4a, the counted value is indicated by a digital indicator 2. When the counted number of the number of times of starting and stopping reaches a preset value, the indication of the digital indicator 2 is subjected to flashing. As a result, it is clearly informed that the maintenance becomes necessary. Therefore, maintenance can be performed before insufficient actions due to excessive wear and the like occur, and hence safety and reliability on the combustion apparatus are improved exceedingly. |
