- mode P+P (pressure + pressure) = in this mode the pump operating mode is controlled within two
pressure levels (Pmin e Pmax); when the lower pressure threshold is reached (Pmin) the pump is started
up, while it is stopped when the upper pressure threshold (Pmax) is reached. In this configuration, the use
of an expansion vessel is essential, sized a ccording to the system requirements and type of pump.
In both operating modes, the device protects the pump from dry running in the absence of water on
intake, by means of a combined control on flow and pressure.
Operation of twin pumping units is admissible only in "P+P" mode.
