Fixed bug that makes ulticontroller knob backwards introduced Feb 28 2013 by Robert.
Bug introduced in version 6beb42cdf65971aeca93868305ed93ae6ed732eb.
Robert did a good job of simplifying but messed up this chunk of code.

Looking at working version: 839bef6d5d436055c6cef051b6b32a84bd18d05a
it seems there is no case where encrot3 should be defined as 2
because if ULTICONTROLLER is defined then NEWPANEL is also defined.
