Thermal system solar controller DELTASOL® CS

The DeltaSol® CS/2 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. For the speed control of high-efficiency pumps 1 input for a VFD Grundfos Direct Sensor™ Heat quantity measurement Commissioning menu 3 basic system layouts to choose from (DeltaSol® CS/4 only) Function control Tube collector function, thermal disinfection (DeltaSol® CS/4 only) Drainback option Unit °C and °F selectable Max. number of collector fields:1 Max. number of stores:1 Weather-compensated heating circuits:- External heat exchanger:- Speed control of standard pumps:check Speed control of HE pumps:check ■ via integrated PWM output:check ■ via PSW adapter:- Hardware Temperature sensor inputs:4 Sensor type:Pt1000 Inputs for Grundfos Direct Sensors™:digital Input for CS10 irradiation sensor:- Impulse inputs for V40 flowmeter:- Relay outputs in total:1 [CS/2], 2 [CS/4] ■ semiconductor relays (speed control):1 (1) [CS/2] 2 (1) [CS/4] ■ electromechanical relay:- ■ potential-free relay with changeover contact:- ■ potential-free relay with normally open contact:- ■ potential-free high-current relay:- PWM outputs:1 ■ convertible to 0-10 V:- Real-time clock:ja [CS/4] Data interface:VBus® Energy-efficient SMPS:check Power supply:100 ... 240 V~ Heat quantity measurement ■ with flowmeter:check ■ with V40 flowmeter:- ■ with Grundfos Direct Sensors™:VFD
