Pleno

Pressure-maintaining monitoring device in the sense of EN 12828-4.7.4. The Pleno ensures that the water reserve required for optimum functioning of the expansion vessels is given at all times. If the level drops below the minimum, water is automatically added to the system. The «fillsafe» electronically monitors and controls the water make-up and ensures maximum safety.
