Abstract
A control system for a low mass hydronic boiler is disclosed which includes a sensor for measuring the temperature of the fluid exiting the boiler. The level of fuel flow provided to the boiler is reduced when the water temperature exceeds a predetermined high temperature limit. The level of fuel flow provided to the boiler is increased only after the water temperature has decreased below a predetermined reset temperature limit and a predetermined interval of time has elapsed.
