Thermal system 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.
