As of Jan 2023, the new model is T3950-IAQ and the pin locations are now different than the original, so the new baseplate will need to be installed so that the wiring and pins match up correctly.  It is no longer possible to just pull the front of the thermostat off and replace it while leaving the baseplate wired to the wall.  Only compatible with 2-wire remote sensors, NOT the 3-wire RS+5/RS1/RSGND versions.
