More $.. I kind of figured that would happen. 500$ be enough? Let's get real. At least I can withdrawal my question and get my $ back. What is the USA coming to. I will call advent personally and get my question answerd for free. Just thought I would give a few bucks to a tradesman. Guess they don't need to help. Have a nice day.

I am pretty tech savvy, but I can't seem to see a wiring diagram. The ones I have been using are from advent and Honeywell. Codes used by each company are completely different.
