Grundfos Pump Switch Boxes

The IO 100 Switch Box is a very simple and easyto- use system with cable terminal connections interface and controlled by a manual on/off switch. The IO 101 acts as an interface for powering back-up supplies, providing automatic change over. When changing from generator to solar energy e.g., the solar modules automatically power the system as soon as the fuel tank runs dry.
