The RESOL DeltaSol BS offers a clear operating concept and is equipped with the newly developed illuminated display with system-monitoring. Flashing symbols for sensors, pumps and valves enable an immediate display of temperatures, temperature differences and active outputs. Adjustment and control of the solar system can be easily carried out.  BS/2 is an improvement from the BS/1 in that it can manage the variable pump speed operation built into the controller
