Abstract
A cycle control system for use with a boiler having a fluid therein and a method of monitoring a boiler to determine the presence of an adequate level of fluid therein. The cycle control system includes a timing circuit producing a burner control signal having alternating on and off states corresponding to on and off period timers to allow foam to settle so that a probe can accurately check the fluid level in the boiler. A burner monitor circuit monitors when a demand controller turns the burner on and off responsive to demand. The on-period timer is reset whenever the burner monitor circuit indicates the demand control circuit has turned off the burner for a length of time sufficient for the probe to accurately check the fluid level.
