Abstract

PURPOSE:To provide detection state of higher sensitivity than that at the ignition by having a flame detecting part which converts the state of flame to a digital signal and changing over the contacts of the flame sensitivity changeover switch in the flame detecting part by the signal from a frequency divider after a fixed time. CONSTITUTION:An inflammable memory part 36 is connected between a burner temperature detecting part 31 and a room temperature detecting part 32 and output control part 34. A delay circuit part 38 which receives the signals from a flame detecting part 29 and frequency divider 37 is connected bwteen the flame detecting part 29 and output control part 34 and a flame sensitivity changeover memory part 39 between the flame detecting part 29 and frequency divider 37. As a result, after leaving a time such as of 100 seconds or other upon detection of ignition by the output of the delay circuit 38, the other clock signal from the frequency divider 37 enters the reset terminal of the flame sensitivity changeover memory part 39 and the contacts of a switch 43 are changed over from 43'' to 43', by which the detecting state higher than that at the ignition may be provided and safe flame detection accomplished.
