    questions Kunde on 25/10/2018

    Werden die Pumpen vom Regler Drehzahlgesteuert?


    Nein, die Pumpen werden nicht drehzahlgesteuert.

    questions . on 24/10/2018

    Kann man die Rücklaufanhebung und Fühler e4 und e5 auch weglassen?


    Wenn Sie ein Anlagenschema mit Rücklaufanhebung benutzen, dann können Sie diese nicht deaktivieren. Sie können am E4 und E5 einen festen Widerstand anschließen, dann ist die Funktion ohne Wirkung. Sie können natürlich auf ein Anlagenschema ohne Rücklaufanhebung ausweichen. Wenn Sie Beispielweise Grundschema 6 benutzen und die Nachheizung benötigen, dann können Sie Grundschema 2 nehmen und A2 nicht anschließen.

    questions . on 18/06/2018

    Wieviele Ampere dürfen in Form der Pumpe angeschlossen werden?


    Leistung je Schaltausgang max. 1A. Gesamtleistung aller Ausgänge 2A.
