T1900 - Platinum Slimline Thermostat Humidity Control 3-Heat/2-Cool
of Jan 2022, the new model is T3900 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.Suggested Accessories
