    Hi Mohamed

    Technically it will work but I would strongly advise against it as it with be considered poor installation practice and against the KNXA guidelines

    When installing a standard cable with a test voltage of 4 kV, the following conditions apply.
    Used wire pair:
    • Red: plus
    • Black: minus
    Spare wire pair: Permitted use of the spare wire pair:
    • no connection at all
    • for other SELV low voltage networks
