In the U.S. an oil fired boiler is turned on and off by the aquastat control. The thermostat starts the circulator; as water temperature returning to the boiler drops it to the cut in temperature the aquastat turns on the boiler. For a warm air furnace the thermostat turns on the burner, the plenum heats up, and the fan limit turns on the blower.
