The Multi controller is designed for solar thermal sys-
tems and heating systems. It is preprogrammed for
7 basic systems or 350 schemes which can even be
used to control large systems. A multitude of adjust able
functions and options are realised by 7 relay outputs,
12 sensor inputs for Pt1000, CS10, V40 and Din. Due
to its intelligent and easy-to-understand system con-
figuration and its integrated calorimeter, the controller
also offers the control of complex systems with up to
4 weather-compensated heating circuits. For data com-
munication and remote maintenance, the controller is
equipped with the VBus
way to modules, PCs or data logging.
