PURPOSE: To simplify time setting at the time of factory delivery and to effectively set data by providing a data set processing program for storing a combustion processing program, combustion control data and time data in a microcomputer in the microcomputer.
CONSTITUTION: A microcomputer 2 has, as memory means, a RAM 4 for temporarily storing data, an EEPROM 5 for electrically erasing and writing, a ROM 6 for storing data set processing program and combustion processing program, etc. The RAM 4 is backed up by a backup battery 3, and even if a power source of a controller is turned OFF, the stored data is held. The microcomputer 2 executes, when recognizes a data set command S1 from a data setter 7, the data set processing program. Thus, an operating man-hour is largely reduced.
