Thanks to the information I got from this great Forum, this past summer I made sure that my contractor installed a 2 stage thermostat to go with our new American Standard Comfort R furnace (2 stage variable speed). The thermostat is the 800 Family 7-day Digital Programmable Comfort Control(http://www.americanstandardair.com/HomeOwner/Products/Thermostats/800Family.aspx).
The heating season has just started and every time the furnace kicks in, it goes into the high 2nd stage, which blows hard and cycles often. Since it is not particularly cold yet, this seems most unnecessary.
I called the contractor, and he said that they usually install a single stage for this furnace and set the furnace for the 2 stages. I told him that to get the most comfort and efficiency from the furnace that the Tstat should be controlling the stages (besides the fact that the furnace clearly was set to run only on high). He said that he'll check with the tech who did the setup. He asked me if I had the manual, and I think that he wanted me to go into the Tstat install instructions and do it myself.
Is it simple to do? I'd rather not, since I don't know what codes I may accidentily enter. However, if they don't usually use this Tstat (they had to ask the supplier which one to order) would they know how to properly set it up?
Is it right that the Tstat should be set up to control the stages? Is it right that I should have the conractor perform this set up?
