I had an Inifinity 96 furnace and stat installed about a 18 months ago. Last week the furnace died and apparently both the tstat and the control board failed. My installer replaced both and left me to re-program the stat (schedule and also options related to the humidifier).
I noticed that the tstat is reporting the furnace as '75 KBTU out' (I'm pretty sure it's a 80KBTU furnace) and also is not reporting the model/serial # in the service menu. Is it possible something was missed when the board was swapped? I remember reading there was a personality plug on the board that had the system information on it. Was that missed?
