RESOL DeltaSol CS Plus

DeltaSol^® CS Plus

The DeltaSol^® CS Plus was specifically developed for the speed-controlled operation of high-efficiency pumps in standard solar and heating systems. It features two PWM outputs and an additional input for a Grundfos Direct Sensor™ VFD, enabling precise heat quantity measurement. The commissioning menu guides through the most important settings for initial configuration in just eight steps.

Delivery includes PWM adapter cable
