Solar controller DeltaSol® BX L

Solar controller DeltaSol® BX L The DeltaSol® BX L is a system controller with 9 pre-defined basic system layouts for 2- and 3-store solar systems. They can be individually extended through a range of additional functions, such as: a thermal disinfection function, a freely adjustable DT function and a heat dump function. cTuVUSThe BX L is equipped with an extra large display, a RESOL VBus® interface and an SD memory card slot for data logging.
