DeltaSol CS – CS Plus
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.
Solar controller DeltaSol CS Plus
The DeltaSol CS Plus has been especially developed for the speed control of high-efficiency pumps in standard solar and heating systems. It is equipped with two PWM outputs and an additional input for a VFD Grundfos Direct Sensor™ that enables a precise heat quantity measurement. The commissioning menu will lead you through the most important adjustments for the initial configuration in only eight steps.
