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.

A water feeder controller for a boiler monitors a low water cutoff sensor in a boiler and uses a feed timer to feed water to the boiler for a predetermined feed period of time. The feed timer brings the water level in the boiler well above the low water cutoff sensor. The feed timer supplies water to the boiler only if the low water cutoff sensor continues to indicate a low water level for a delay period of time measured by a delay timer. A resettable display indicates the quantity of water supplied by the water feeder to the boiler based on a feed counter incremented during water feeding. A manual feed button allows water to be manually fed to the boiler. The quantity of water manually supplied to the boiler is also shown on the display. The feed timer and delay timer are preferably implemented in software in a microcontroller in the water feeder controller. A lockout loop in the software prevents overfeeding of water to the boiler in the event of a failure of the low water cutoff sensor.

A control system for use with a boiler and associated burner. In one embodiment, the system comprises a first control circuit for producing a signal having alternating first and second states, the first state activating the burner and having a first predetermined duration, the second state deactivating the burner and having a second predetermined duration that defines a time period that allows foam and surging fluid in the boiler to settle, and a relay responsive to the first control circuit signal and adapted for connection to a power source and the burner, when the first control circuit signal has the first state, the relay connects the power source to the burner to activate the burner, when the first control circuit signal has the second state, the relay disconnects the power source from the burner to deactivate the burner. In another embodiment, the system further includes a sensor for continually monitoring the fluid level in the boiler, the sensor producing a signal having a first state indicating that the fluid level in the boiler is at or above a predetermined level and a second state indicating that the fluid level in the boiler is below the predetermined level, and a second control circuit responsive to the sensor signal and having an output coupled to the relay, the second control circuit producing a signal having a first state in response to the first state of the sensor signal and a second state in response to the second state of the sensor signal, the relay connecting the power source to the burner when the first and second control circuit signals have the first state and disconnecting the power source from the burner to deactivate the burner when the first control circuit signal or the second control circuit signal has the second state.
