    Default How do I wire this extractor fan to GHL BoB?

    I am installing a variable speed air extractor above my tank which will extract humid air to the outside. I want to run the extractor via my Profilux 4 and control the speed depending on the readings from the GHL temp/humidity sensor.

    So I purchased a GHL break-out box but now have no idea on how to connect the extractor to the box for the 0-10V control (220v is supplied to the extractor separately).

    Attached are five diagrams from the extractor documentation. My guess is the diagram number 26 is the one I want? But it only shows two wires, ground and 0-10v. can only two wires be connected to the GHL break-out box?

    Help!

    Fantastic... Thanks Pit, your help is much appreciated!

    Soon I will also have the question as to how to program the Profilux to manage the extractor :-)

    But I will start a new thread for that one...
