The DeltaSol® E controller is designed for solar thermal systems and heating systems. It is pre-programmed for 7 basic solar systems and up to 30 variations which can even be used to control large systems. A multitude of adjustable functions and options are possible using 7 relay outputs, 13 sensor inputs for Pt1000, CS10, V40 and Din. Due to its intelligent and easy-to-understand system configuration and its integrated calorimeter, the controller also offers the control of complex systems with up to 4 weathercompensated heating circuits. For data communication and remote maintenance, the controller is equipped with the RESOL VBus®, which permits two-way communication between modules, PC‘s or data loggers.
