Energy saving circulating pumps 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 panel Fixed speed mode:...
