Honeywell Home THX900B2 ElitePRO S900 Smart WiFi Thermostat, Black, 3H/2C

Description

The Honeywell Home ElitePRO S900 Smart Thermostat delivers premium design and pro-grade performance for residential and light commercial installs, including 24 Vac gas, oil, electric warm air, hydronic, fan coil, and PTAC systems. This hardwired, C-wire-required thermostat features a 4.3 sq. in. customizable touchscreen with selectable English, French, or Spanish display, and supports heat, cool, auto, off, and emergency heat modes across up to 3H/2C heat pump or 2H/2C conventional staging. Auto or manual heat-cool changeover and time-based or Smart Away programming give installers flexibility for both residential and light commercial jobs. Built-in humidity sensing (5–90% RH operating range) and a configurable control output let techs manage IAQ equipment or add an extra heating/cooling stage on the same unit. Rated for ambient operating temperatures of 37°F to 102°F, the ElitePRO S900 mounts to a standard J-box in a horizontal wall orientation using the UWP wall plate for faster installs and upgrades. WiFi-enabled and Matter-compatible, it works with Google Home, Amazon Alexa, and Apple Home, and is backed by a 5-year warranty, ENERGY STAR certification, and utility rebate eligibility. The sleek black finish suits homeowners looking for a modern, stealth-profile aesthetic. This model replaces the TH6320WF2003/U and TH6220WF2006/U, making it a drop-in upgrade for existing Honeywell installs, and is supported by Pro-IQ services through the Resideo Pro app for remote setup, saved install templates, and system alerts.
