Description:
SR881 solar pumping group with integrated controller 868C9 is an advanced solution for managing and automating solar installations for domestic hot water heating. This pumping system is equipped with an intelligent solar controller model SR881, specially designed for pressurized solar installations, and includes a high-quality recirculation pump from Grundfos, an electronic flowmeter, a differential temperature probe, a manometer and a safety valve.
In addition to the standard functions of solar stations, the automated SR881 pumping group measures the solar energy captured daily and cumulatively. It also allows adjustment of the water circulation speed according to the temperature difference between the solar panel and the hot water boiler, within a range between 30% and 100%, thus improving the efficiency of the entire system.
