Automatic selfoptimising and pressure regulated control unit for pumps

The invention concerns a new control unit for pumps ( 3 ) for heat- and chill-transferring media, which records all parameters for the regulation of the pump in or close to the pump independently from the distance to the heat source ( 2 ) or cooling source. Thus the often complex wiring between heat source ( 2 ) and heat sink ( 1 ) and/or cooling source and cooling sink is omitted. The control unit may be installed directly on the pump ( 3 ) or integrated in the pump consequently. The controller recognizes self learning due to the evaluation of the operating conditions typical system parameters, so that the positioning of the system-dependent temperature differences for control processes is not necessary and can be omitted. The construction of the pump ( 3 ), integrated controller ( 4 ) and sensors ( 7, 8, 9, 10 ) close-up range enables a manufacturing of completely pumps prepared for the operation including a controller in extremely compact construction.
