    vdm not working as expected

    Hello I have a apex jr with vdm I had everything taken apart for about 6 months and putting it all back together today. my waveline 2500 apex enabled is not taking speed control at all. and my 0-10v prioair 8ec fan is taking speed control but in reverse ie... 0 is full speed 100 is off, but it will only turn on at 70 and that will be slow but 10% is super fast

    I have the latest firmware and the vdm is firmware 13

    Hard to troubleshoot without a lot of additional information. We need pictures of your setup and wiring, types of connectors used, and if you have a voltmeter readings from the cables.

    You might be an engineer if...You have no life and can prove it mathematically.
