What does it mean when a boiler can modulate? - Green

1) Modulating occurs: If the boiler can modulate it will detect the high return temperature and turn the flame down, the return temperature reduces and the boiler stays in condensing mode. If the boiler cannot turn the flame down far enough it will start to cycle as well.

Oil-Fired Boilers and Furnaces | Department of Energy

An aquastat controls the temperature of the hot water in a boiler, typically keeping it around 180°F. But when heating needs are lighter in the spring and fall, that's actually higher than needed, and wastes energy. A modulating aquastat, also called an outdoor reset, senses outdoor temperatures and adjusts the hot water temperature accordingly.
