This control may switch on and off a single circulator pump, and if a tankless coil is installed on the boiler, it may also turn the oil burner on and off as needed to maintain temperature in the boiler to provide domestic hot water as well. Combination Control High Limit: On a typical combination control, the "Hi Limit" is the cut-off temperature for the heating boiler on a call for heat. The cut-on temperature is hard wired in this control …

A low water cutoff is a device that detects when the fluid level in hot water and steam boilers drops below the minimum safe operating level specified by the boiler manufacturer. If this should occur, the low water cutoff will cut-off the burner and shut down the boiler. If a boiler is "dry-fired" (burned without water in it), it can result in boiler failure, or a possible fire/explosion.

Combined heat and power (CHP) is the simultaneous cogeneration of electricity and heat. Cogeneration is a highly efficient form of energy conversion and using gas engines it can achieve primary energy savings of approximately 40% compared to the separate purchase of electricity from the electricity grid and gas for use in a boiler.. If the fuel for the gas engine is renewable such as biogas

Boiler water is up to the correct level, closing the low-water cutoff switch. The low-water light (panel) is off. The operating limit pressure control (steam boiler) or the operating limit temperature control (hot water boiler) and high limit pressure or temperature control are below their cutoff setting.

Low Water Level: A level switch stops the burner if the boiler water level gets too low. If the water levels gets low enough that part of the boiler runs dry, that part can overheat, weakening it and possibly resulting in an explosion.
