DeltaSol CS Plus differential temperature controller including 4 sensors

• For simple solar thermal systems and solid fuel boilers
• For standard and high-efficiency circulation pumps with PWM signal
• With 4 inputs and 2 outputs

The DeltaSol® CS Plus was specifically developed for 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 metering. The commissioning menu guides the user through the most important settings for initial configuration in just eight steps.
