of Jan 2022, the new model is T3800 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.
