Honeywell Home YTHX1200 ElitePRO S1200 Smart Thermostat with Sensor
Honeywell Home YTHX1200 ElitePRO S1200 Smart Thermostat with Sensor - White is backordered and will ship as soon as it is back in stock.
The Honeywell Home YTHX1200 ElitePRO S1200 Smart Thermostat with Sensor turns your wall control into a second look at the front door while it manages comfort and air quality behind the scenes.
Behind the 5 inch full-color customizable screen sits a control platform built for both homeowners and HVAC professionals. It runs residential and light commercial 24 Vac equipment, including dual-fuel, fan-coil, PTAC, and radiant systems, which makes it a fit for a house or a small office suite.
Key Features and Benefits of the Honeywell Home YTHX1200 ElitePRO S1200 Smart Thermostat with Sensor
- Multi-Stage Compatibility: Handles up to 4H/2C heat pump or 3H/3C conventional equipment, so staged and dual-fuel systems run from a single control.
- Customizable Touchscreen: The 5-inch touchscreen sets heat from 40 to 90 degrees F and cool from 50 to 99 degrees F, with a customizable idle display that prioritizes the information you need the most while matching your room's style and color scheme.
- Air Quality Monitoring: Onboard monitoring tracks indoor humidity (included), VOC, and estimated CO2 levels to maintain a healthier home.
- IAQ Device Control: Configurable outputs operate up to 2 indoor air quality devices, letting a humidifier or ventilator respond to what the thermostat measures.
- Doorbell Integration: Streams video from First Alert and Ring doorbells to the screen, with 2-way audio so you can answer without walking to the door.
- Wi-Fi Control: Use the First Alert app for full control with your smart device, letting you set auto control, smart schedules, and thermostat changes to manage your space. You can also get Alerts, reminders, and monthly energy reports directly to your device.
- RedLINK Wireless: RedLINK 3.0 links the thermostat wirelessly to the included room sensors, an equipment interface module, and outdoor temperature and humidity sensors.
- Included Room Sensor: A wireless C7189R3010-2 room sensor reports temperature, humidity, and motion from the room you care about most.
- Occupancy Detection: An onboard radar sensor recognizes when rooms sit empty and eases back on conditioning to cut wasted runtime.
- Flexible Scheduling: Program 7 days with 4 time periods per day, or switch to Smart Away mode so conditioning follows when the space is actually occupied.
- Fan Speed Control: Fan-coil applications run up to 3 fan speeds, letting you match airflow to the load rather than running flat out.
- Resideo Pro App: Your installer can save and reapply setup templates through the Resideo Pro app, which speeds installation and reduces configuration errors.
- Certified and Covered: Energy Star certified for efficient operation, and backed by a 5-year warranty.
Matching the Finish to Your Wall
Both finishes carry the same hardware and specifications, so the decision comes down to where the screen will live and how visible you want it to be. The white version blends into light drywall in a hallway or bedroom, while the black version reads as a deliberate accent against dark paint or wood paneling. Measure before you mount either one, since the thermostat covers 3.54 x 5.24 x 0.96 inches (H x W x D) off the wall, weighs 0.91 pounds, and fits a horizontal J-box using the included UWP Wall Plate and cover plate. Keep it in a conditioned space as well, because it is rated for ambient conditions from 37 to 102 degrees F and 5 to 90 percent relative humidity.
Sylvane's Expert Take
If you install and service HVAC systems across homes and light commercial properties, this thermostat gives you one control to standardize on instead of stocking several. Confirm whether a C-wire is present before you quote the job, since power is for hardwired only and pulling a common wire on an older install can add additional complications.
The radar-based occupancy detection and the 2 configurable air quality outputs are what your customers will notice, one easing back conditioning in empty rooms and the other tying a humidifier or ventilator to live readings rather than a fixed schedule. Whichever finish you mount, this is the thermostat to reach for when a client wants air quality control and a screen they will actually use.
