Not knowing the model numbers and if the stat is a programmable heat and cool stat, I will tell you how to wire one that is. On the stat you should have terminals marked RC, RH, Y, G, W. If this is a furnace only with a terminal board, Start at stat. You should have only 2 wires for heat only. Red will go to RH and leave the jumper wire that goes from RH to Rc in place.The other may be white and will go to W. Same at the furnace R to R and White to W.Let me know if this is you're set-up and if not tell me the terminal markings on the stat and carrier furnace and if it is heat only.

Welcome to Fixya.
This error code implies "heating or cooling equipment missing"- on easier terms, something might be disconnected or incomplete as you may not have everything hooked up. If so, you need to go to the installer menu to make sure you have the correct settings.
Here's a user's manual just in case :
