A pool pump controller is a device that allows you to speed up or speed down your pool pump. This allows you to get the energy-saving benefits of a variable speed pump, without having to replace your existing pump.
A controller is able to do this, because of variable frequency drive technology. This drive varies the frequency and voltage of the power supplied to the pool pump, allowing it to speed up or speed down.
One of the benefits of the controller, is that it’s a plug and play device that can be installed yourself. Simply plug it in, press the energy saving button and the device will automatically run the pump at optimal settings.
