Root causes:

  1. the dim zones are not wired correctly

  2. the dim zone is broken in the PHD

  3. the fixtures were not programmed to dim to off


  1. Ensure that the fixtures are wired over to purple correctly

  2. Check that the circuit makes it to the first fixture from PHD

  3. Check voltage at the 0-10 controller on the PHD, seeing 1.3V at 10% and 9.7V at 100%, so lights SHOULD be dimming, as they do elsewhere onsite.
