I had the same one installed recently in much warmer Nashville area. Except it was called a 9521A rotor and came with a 9537A remote. Installer had similar problem not getting it to rotate from 0 degrees north clockwise a full 360 degrees. Mine would only rotate to 8 o'clock.
He had to realign it correctly by doing the following:
(1) press 180 degrees in the remote
(2) realign the dot and the arrow on the 2 parts of the rotor to touch each other
(3) physically, manually on top of your tower, keep the dot and the arrow lined up and turn the whole rotor to face 180 degrees due south
(4) turn your antenna pole above the rotor to face due south
(5) tighten down all the bolts
(6) press the sync button to verify it goes counterclockwise back to 0 degrees and then returns to 180
(6) press the 320 on your remote and see if it rotates clockwise to the correct location
Also I prefer to use one universal remote for TV, sat, DVD, and the rotor. The Pioneer cable box remote code worked fine on my universal remote.
Good Luck !
