Sometimes if the system has low inhibitor the limescale can lead to the valve becoming stiff when operated, holding the switch closed when power removed, causing the heating to run on. Modulating, or AME actuators, are appropriate for precise regulation of the flow as they also have feedback signal and can position themselves very precisely in accordance to the signal from the controller.
