Abstract:
(EN) The present invention relates to a method for operating a circulation pump, in particular a heating circulation pump, having a variable-speed pump drive, wherein the pump controller modifies the actual operating point of the pump in order to reduce the noise emission of the pump.
(FR) La présente invention concerne un procédé pour faire fonctionner une pompe de circulation, en particulier une pompe de circulation de chauffage, comprenant un entraînement de pompe à vitesse variable, l’invention étant caractérisée en ce que la commande de pompe modifie le point de fonctionnement instantané de la pompe afin de réduire l'émission sonore de la pompe.
(DE) Die vorliegende Erfindung betrifft ein Verfahren zum Betrieb einer Umwälzpumpe, insbesondere einer Heizungsumwälzpumpe, mit einem drehzahlvariablen Pumpenantrieb, wobei die Pumpensteuerung den aktuellen Betriebspunkt der Pumpe modifiziert, um die Geräuschemission der Pumpe zu reduzieren.
