DESCRIPTION
Press•o•Matic is an ele ctronic device , employing in verter-based tec hnology, whic h c ontrols motor pump
stopping and starting func tions.
Thank s to the p artic ular type of tec hnology use d, it c an modulate the freque ncy (Hz) of the motor’s input
curre nt to alte r the spe ed (rpm) acc ording to the wate r delivery rate required from the system.
This way, the value of the pressure reac hing the user appliance s is maintained constant all the time and
the motor's absorption is al ways proportional to the actual syste m requirements, resulting in notable
energy savings o ver time. All o ther uses are strictly prohibited.
