Thermostat is in exact same spot as the old one. I'm not sure what you
mean about size. I know next to nothing about furnaces. The quote
says "Carrier 58 MVP 96%". Also don't know what a "VS DC" is. It
does have a variable speed fan that can be left on all the time at low,
medium or high and an auto setting.

My installer is going to have someone from Carrier come. He's
convinced there's a bug in the thermostat. All I know is we are
miserable.

That reminds me, the hole in the wall behind the thermostat needs to be sealed up because it will allow the air temperature from inside the wall to interfere with the reading of the room temperature. 8-)
