Description
Description
Resol DeltaSol® CS/2 and CS/4 are solar controllers for speed-controlled activation of a high-efficiency pump in small standard solar and heating systems. Both have a PWM output and an input for a Grundfos Direct Sensor™ VFD for heat quantity measurement.
The CS/2 has one semiconductor relay, the CS/4 has two semiconductor relays and 3 selectable basic systems. Configuration is carried out via a commissioning menu. According to the manufacturer, a PWM adapter cable is included in the scope of delivery.
