Thermal system solar controller DELTASOL® SL

With its versatile software, the DeltaSol® SL can control even complex systems easily and reliably. 27 pre-configured system layouts with up to 3 hydraulic variants each facilitate the commissioning and enable the adaptation to the individual system requirements. The operation via 2 main buttons and 1 adjustment dial, the Lightwheel®, still follows the well-known operating concept. The multicoloured LED, integrated in the Lightwheel®, offers many possibilites to signal different system states. The microSD card slot and the 2 microbuttons for quick access to the manual mode and the holiday function are located underneath the slidable housing cover, the SLider. 4 relay outputs (incl. 1 potential-free extra-low voltage relay) 4 inputs for Pt1000, Pt500 or KTY temperature sensors Input for 1 analogue Grundfos Direct Sensor™ 1 V40 impulse input (also usable as a Pt1000, Pt500 or KTY temperature sensor input) 2 PWM outputs for the speed control of high-efficiency pumps 27 basic system layouts with up to 3 hydraulic variants each to choose from Automatic function control according to VDI 2169 Data logging, easy transfer of controller adjustments prepared and firmware updates via SD card Max. number of collector fields:2 Max. number of stores:2 Weather-compensated heating circuits:- External heat exchanger:check Speed control of standard pumps:check Speed control of HE pumps:check ■ via integrated PWM output:check ■ via PSW adapter:check Hardware Temperature sensor inputs:4 (54) Sensor type:Pt1000, Pt500, KTY Inputs for Grundfos Direct Sensors™:analogue Input for CS10 irradiation sensor:- Impulse inputs for V40 flowmeter:1 Relay outputs in total:4
