Trying to help a friend with his 2005 U320. The 3 zone AC with 5 button comfort control center is inop. All 3 units do not operate. An attempt to reset the control center results in an "EE" display on the comfort control center--- any thoughts on wha the issue might be---hot and no AC!
Check the connection on the wire to the AC unit in front. It is a phone jack extender and a known failure point. You might even just plug the control unit right in that line and see if it works as a start.
We tried that, no luck so he is dropping his coach off at Foretravel on the way home for repair.
We had a similar problem. Fix was a 5 amp fuse on the circuit board in the front AC. Remove cover, remove metal cover box, find fuse, check. Maybe? Roger

Found this on another forum.... "EE is a data communication error code. As well as low or dirty dc voltage, this error can be bad connections between t'stat and unit, bad t'stat, bad control board."
Try to do a reset as described in the doc above.
