Resol - Model DeltaSol SL -Solar Controller
FromResol GmbH
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.
