With these old Carrier models being discontinued. We will send the current model Venstar T2900 which is identical in every way (looks, size, features and programming). These Carrier models were made by Venstar and just had the Carrier logo put on them. So, the current model we send you will be an exact fit replacement.
of Jan 2022, the new model is T4900 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.
