DeltaSol^® CS/2

The DeltaSol^® CS/2 is equipped with a semiconductor relay and can be used for speed control of a HE pump in small standard solar thermal and heating systems. Furthermore, it is 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.

Small solution for standard solar thermal and heating systems
High efficiency even for small systems
Quick configuration due to commissioning menu
