We do a lot of tracker and varitrac in our office and they are not difficult to set scheduling in if you follow the manual. It is just really time consuming setting them up because of the way they are set up in the display. If you follow the manual scrooloose sent you it should be no problem. Some of the comments were correct in that usually these panels are installed by mechanical contractors we rarely sell them in Trane contracting for a job. Our sales dept. is usually pretty good in adding in a little cost to the mechanical contractor for me to go out and spend a little time showing them how to use it and make sure it is set up properly to hopefully stop this kind issue.
