  • Combustion control device
    Patent number: 8485137
    Abstract: The present invention relates to a combustion control device incorporated in an apparatus such as water heater and provides the combustion control device having an improved configuration with a main controller and a sub controller, capable of employing a microcomputer with lower capability as the sub controller, and ensuring higher safety than ever before. Signals indicating a combustion state of a combustion apparatus are inputted into the main controller 35 and the sub controller 36 in parallel. Upon fulfillment of a predetermined condition of stopping, the main and sub controllers 35 and 36 each output a stop signal to cut off a current to be supplied to a device driving circuit 42. The conditions of stopping in outputting of the stop signal by the main and sub controllers are such that the sub controller 36 is less apt to execute the cutoff than the main controller 35.
