Solar controller DeltaSol CS/4

Description

Solar controller Resol DeltaSol^® CS/4

The DeltaSol^® 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.

DeltaSol® CS/4
■ 3 basic system layouts (DeltaSol® CS/4),
■ Tube collector function, thermal disinfection function
A PWM adapter cable is included with the controller.
