A multitude of adjustable functions and options are possible using 7 relay outputs and 10 sensor inputs for Pt1000, CS10 and V40. 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 weather-compensated heating circuits. For data communication and remote maintenance, the controller is equipped with the RESOL VBus®, which permits two-way communication between modules, PCs or dataloggers.
