The best thing about LCN: You do not need to worry about anything. The regulation of these energy saving options runs automatically and is perfectly adjusted to your wishes. Presence detectors recognize when someone is in the room. In this case, the LCN operates under different settings than if the room were not being used. Then, the heating would be turned down and the light automatically switched off. The heat output is also reduced as soon as a window is opened. Thus, saving energy does not become a necessity but rather something quite ordinary.
