Abstract

Das Pumpenaggregat ist für Heizungsanlagen vorgesehen und besteht aus einer Kreiselpumpe, die von einem Elektromotor angetrieben wird. Im Elektromotor ist ein Drehzahlsteller sowie eine elektronische Regelung zugeordnet. Über eine separate Einstellvorrichtung können die Betriebsparameter des Aggregates eingegehen werden. Werkseitig ist das Pumpenaggregat auf eine Regelkurve voreingestellt. Da sich am Pumpenaggregat selbst keine Einstellmöglichkeiten befinden, ist eine Änderung dieser Parameter nur über eine separate Einstellvorrichtung möglich.The pump set is intended for heating systems and consists of a Centrifugal pump driven by an electric motor. In the electric motor assigned a speed controller and an electronic control. Over a separate setting device can enter the operating parameters of the unit become. The pump set is preset to a control curve at the factory. Since there are no adjustment options on the pump unit itself these parameters can only be changed using a separate setting device.
