ONEMATIC easy
0. DESCRIPTION.
ONEMATIC easy
is a compact automatic control unit for single-phase elctric pumps. The system manages the start and stop of the
pump depending on the pressure detected by its internal transducer and the flow detected by the internal flow sensor. It can be run
either in
pressure-dependent mode
(start pressure and stop pressure) or
on/off mode
(start pressure between 1÷5 bar, stopped by
the flow sensor).
