At this point, I can't tell if you are intentioinally baiting me by continuing to call me a liar or if you are just plain ignorant (I'm leaning toward the latter). I stated multiple times in this thread that 1.) I was not looking for step-by-step instructions. 2.) I had already hired a competent tech, but like to have some working knoweldge on a subject before calling him. 3.) It was not a DIY job............
In either case (bating or ignorant), this is clear evidence that anyone considering hiring you should think twice. Why can't you understand that a non-DIYer would still like to edify himself on subject in which he is making a MAJOR financial investment? Why are you afraid of consumers being knowledgeable about the investments they are making? What do you have to hide?
All I was looking for was a simple explanation of what a "Universal Relay" was.....That is no reason to call me a liar. A simple explanation would have sufficed, or simply ignoring the post would be fine, but instead you chose to accuse of of lieing.
As for burning out parts, how would giving an explanation of what a universal relay is burn out parts? Something as simple as "A U.R. is a device about the size of an ice cube. It would be installed outside the thermostat (not in it). It can be configured in a manner so that when current is passed from the t-stat, it would prevent the current from reaching the motorized duct. Similarliy, when the t-stat is not sending current, the U.R. would send it. This would effectively reverse the action of my damper and produce the desired effect". This is what I eneded up learning by calling an electrician friend of mine.....A far cry from step-by-step instructions, again which I never asked for.
Thanks again for those on this board who offer constructive comments rather than making baseless claims that someone is lieing.
