Functions of the control unit

The Wilo Sirio 3x230 control unit can be used when we need to take advantage of continuous pump speed control. Sirio 3x230 allows you to control the output pressure in a very narrow control zone, which leads to a change or complete removal of the pressure vessel on the discharge pipe. It also contributes to the reduction of energy intensity, noise and the overall lifetime of the system.
