Solar controller DeltaSol<sup>®</sup> CS

Solar controller DeltaSol® CS

The DeltaSol® CS/2 and CS/4 controllers are used for speed control of a HE pump in small standard solar thermal and heating systems. They are equipped with a PWM output as well as with an input for a VFD Grundfos Direct Sensor™ which enables precise heat quantity measurement. The commissioning menu ensures an easy and quick configuration.
