Congratulations and thank you for your purchase of the VFDC-3000 controller. This manual explains the
features and operations of the controller which was designed to operate up to 3 pumps in a constant pressure
application. The controller automatically adjusts pump speed and the on and off pump sequence in response
to changes in the system pressure. When used to control the system pressure, a 4-20mA pressure transmitter
is connected to the input. The controller features a rotary selector knob in addition to left shift and escape
push buttons for intuitive menu navigation and quick setting adjustments.
