COMBUSTION SYSTEM

摘要

In a status that a combustion system is disclosed, when the EEPROM is initialized in step S1, the system moves to step S2. The writing circuit writes the standard adjustment value data about the Lo/Hi side extinction determination level and the proportional valve current of a group(7) extinction level and the fan current of the groups(1,7) to the EEPROM. Thus, an abnormal operation state before adjustment process of the combustion system in which the adjustment value data of a control circuit is written in a semiconductor non-volatile memory can be eliminated.
