RESOL has introduced its DeltaSol E solar thermal systems controller, which is pre-programmed for seven basic systems and up to 30 pre-programmed variations.
The company says a multitude of adjustable functions and options are possible using seven relay outputs and 13 sensor inputs. Because of the product's intelligent and easy-to-understand system configuration and integrated calorimeter option, the controller also offers the control of complex systems with up to four weather-compensated heating circuits using additional heating circuit modules.
For data communication and remote maintenance, the controller is equipped with the RESOL VBus, which permits two-way communication between modules, PCs or data loggers.
