Pressure maintenance monitoring devices

Pressure maintenance monitoring devices in accordance with EN 12828-4.7.4. Models of the Pleno Connect range ensure that the water reserve required for expansion vessels to operate at optimal efficiency is available at all times. If the level drops below the minimum, water is topped up automatically. The «fillsafe» function electronically monitors and controls water make-up and guaranteees maximum system safety.
