Works as designed for Grundfos submersible pumps.
While not the cheapest controller (understatement), it is designed to work with Grundfos submersible pumps to provide constant pressure rather than conventional controllers that pressurize to a top limit, dropping pressure until the lower limit is hit and then recharging to the top limit.
Purchased V7 to replace V5 controller from 2008 which as a computer died.
