6.5 Installer parameters
Many of the Installer parameters are set during the Initial Configuration (chapter 6.2 Initial Configuration).
However, through the Installer Parameters menu, it is possible to change the set parameters or set others in order to perfect
the calibration of VASCO to the pumping system.

Mode of control:
 Constant pressure: VASCO changes the speed of pump to keep the
pressure constant, independent of water demand
 Fixed frequency: VASCO feeds the pump a set frequency, so the speed of
motor is kept constant.
 Constant pressure control with two values; the two values are selected by
opening or closing the digital input 2.
 Fixed frequency control with two values to be selected by opening or
closing the digital input 2.
 External speed: control motor frequency by using analogical input .
 Constant temp.: VASCO changes the speed of pump to keep the
temperature constant. An analogical signal coming from a temperature
sensor must be connected.
 Constant flow: VASCO changes the speed of pump to keep the flow
constant. An analogical signal coming from a flow sensor must be
connected.
