Geyser Controller & Grundfos Pump

A thermal controller is like the window to the condition of your solar array. It’s not part of the components that make it function, instead, it’s there to help you get the most out of your investment. The Controller puts you in a position to check on several critical points, such as the temperature of the tank or the collector. Through a digital screen and a user friendly interface, you’ll easily be able to monitor whether your solar array is staying in shape.
