Inifinity 96 Control Board & Tstat replaced, now a question
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?
Yes that is a communicating furnace, there is a chip that plugs into the board that has info about that system including your serial # on it, the chip should be transfered to new board, Contact them immediately.
Thanks! I'll give the tech a call...
The 'chip' is called a model plug and it contains no serial information. I can build the model plug with components from Radio Shack.

If the UI is reporting 75K out, then the model plug is installed.
75/80 = 93.75% which is about right for an 18-month old Carrier Infinity 96.
No need to call the tech.
Perhaps you should have read the instructions before calling.
jrbenny is 100% correct you will not see m&s #on stat again if board was replaced you should be ok just reprogram your settings
OOops MY bad, the trane communicating furnaces require you to do as I said. Apparently this system is different. Sorry Mr or MRS. homeowner, didnt mean to scare you, pretty sure these guys know what they are talking about.
