Boiler Operation and Controls - Wiki - odesie by Tech Transfer

In the case of a steam boiler, the control device is a pressure sensing element that sends a signal to the burner management system to adjust the burner firing rate to maintain a set pressure in the steam distribution system. In a hot water boiler, the control device is a temperature-sensing element.
