Liegt jedoch zusätzlich L (3) an, öffnet es. Dies ist auf dem Gehäuse des Motorantriebs eingezeichnet und beschriftet.<BR />Ich empfehle jedoch, für weitere WP-Anschlüsse einen Elektriker zu beauftragen.</P><P>&nbsp;</P><P>Ich warte noch auf Ihre Antwort bezüglich der Sprache der Anleitung.</P><P>&nbsp;</P><P>Hello</P><P>I am attaching a wiring diagram.</P><P>The motor valve works like this:<BR />For the closed position, it requires constant power supply to N (1) and L (2), but when L is also on (3), it opens. All of this is drawn and written on the motor drive housing itself.<BR />However, I suggest that you hire an electrician for further WP connections.</P><P>&nbsp;</P><P>I am still waiting for your answer for the language of the instructions.</P><P>&nbsp;</P><P>Bonjour</P><P>Je joins un schéma de câblage.</P><P>La vanne motorisée fonctionne ainsi :<BR />En position fermée, elle nécessite une alimentation électrique constante aux bornes N (1) et L (2), mais lorsque L est en position (3), elle s'ouvre.
