T1900 - Platinum Slimline Thermostat Humidity Control 3-Heat/2-Cool
T3950-IAQ will be the new model replacing the T1900 and T3900

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.

7-Day Programmable 3-Heat, 2-Cool Thermostat is the premier Platinum series model that is equipped with the Humidity Module for advanced Humidification, Dehumidification, and Reheat control and is compatible with a wide array of valuable accessories including wired and wireless Remote Sensors and Comfort Call for remote phone control (see below). It features a backlit display and buttons along with a classically attractive, slim bright white design that looks great on any wall. For use with most Air Conditioning & Heating Systems including: 1 or 2 Stage Electric Cooling & 3 Stage Gas Heating, Heat Pump, Dual Fuel, Electric or Hydronic Heat.
