Abstract
PURPOSE: To permit a safe and reliable starting of combustion by instantaneously turning on a semiconductor switching element having a safety breaking switch as a load when a combustion controller is started and proceeding with the sequence hereafter according to the signal obtained then.
CONSTITUTION: The combustion controller has a state discriminating circuit 10, a safety switch driving circuit 20, a load control latching circuit 30, the first through third timer circuit 40 through 60, a load relay driving circuit 70 and the like, the safety switch driving circuit 20 comprising a transistor Tr23 and a safety switch load 24 such as an instantaneously operating breaking switch. In order to detect the switching state of said Tr23, a NAND gate 27 is provided which inputs signals from the collector 25 of the Tr23 and a state detecting signal C1 from the first timer circuit 40 which applies a prepurge timing. The output of the gate 27 is outputted through the latching circuit 30 to the load relay driving circuit 70 and a fan motor driving circuit (not shown).
