Function of
Multi Eco-Top
When the system pressure drops, the pump (1) is automatically started via the
pressure switch (3). When the required pressure has been reached, the pump is
stopped automatically.
The membrane-type accumulator (2) serves to limit the frequency of pump starts by
providing smaller amounts of water from the volume stored.
