DMX Mapping Change in V1.2.0 - Multizone Modes

Versions before V1.2.0 had the Fan Channel control in the FIRST SLOT, for Multizone Modes.  In V1.2.0 (and later versions) this moved to the LAST SLOT.

Make sure to use the correct DMX profiles in your console, or Multizone modes won't work correctly.
