I did a carrier A/C to Advent conversion There is one of the plugs that has to be changed (Poor Service Tech did not know how to install the Snap in socket.... Of course I did (I'm electronics trained).
Alas. the only "Senor" i know of in the Carrier is the frost sensor that you poke into the Evap coil... and of course the little Room temp senor that's mounted on the board (you don't plug it in it sticks out a hole in the cover)
Did not do a heat pump.. So don't know where it goes.
Home was where I park it. but alas the.
