Series Version for sanitary hot water DN ports in mm With flanges Max. head in dm connection size mm Features Smart pump NCE GS.F adapt its functions to the system: the circulator measures the pressure and the flow and adjusts the speed to the selected pressure. There are different operating modes selectable from the control

Energy saving circulating pumps with flanges for sanitary hot water Operating modes Automatic mode (factory setting): In this mode the pump automatically sets the operating pressure, depending on the hydraulic system. This mode is recommended in most systems. Proportional pressure mode: The circulator changes the pressure propotionally to the current flow. The pressure value can be adjusted with the + and - buttons. Constant pressure mode: The circulator mantains the pressure constant when the reference flow changes. The pressure value can be adjusted with the + and - buttons. Operating mode-control...
