The DeltaSol® SLT effortlessly controls even complex systems. 27 pre-configured system layouts with numerous pre-programmed optional functions such as thermal disinfection or zone loading enable 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 possibilities to signal different system states. The micro SD card slot, the mini USB connection and the 2 micro buttons for quick access to the manual mode and the holiday function are located underneath the slidable housing cover, the SLider.
