The SOM 8 plus solar control unit features a clear control concept and many application options. It regulates solar thermal systems for large and small installations alike, incl. DHW heating, central heating backup and/or swimming pool heating. The large, backlit full-graphics display shows statement and curve diagrams. The multilingual guide through the menus makes operation easy and precise. The controller is pre-programmed with nine variable standard systems. These can be adapted to the individual solar thermal system or heating system with a great number of additional optional functions. The controller offers up to two integrated heat meters and the control of two weather-compensated heating circuits. The SOM 8 plus is a well turned-out combination of functionality, price and design.
