Comfort When Home, Savings When Away
The Honeywell Home app uses geofencing, so the T9 knows when you're coming and going. No matter your schedule, you can always come home to comfort and save energy when you're away.
Smart Response & Alerts
The T9 learns your home's heating and cooling cycles to help deliver the optimal temperature at the right time. Plus you can be alerted when it's time to change your filters and when temperatures get too high or low.
Smart Sensors, Smart Living
Place smart room sensors where you want to see each room's temperature and humidity. Use the multi-room display on the thermostat's touchscreen or in the app to easily focus on rooms either based on their occupancy or according to a specific schedule you choose.
When focused on multiple rooms, the T9 will work towards creating an average temperature, balancing the needs across the whole home.
Purchase the T9 bundled with a sensor, and expand the system by adding up to 20 additional sensors.
WHOLE HOME COVERAGE
Our sensors have a stronger signal that can reach up to 200 feet and penetrate further and deeper across the whole home. This also means the quality of the signal and data presented to the T9 is increased, allowing for greater learning and control. Thick walls and flooring can't stand between you and home comfort.
With Smart Room Sensors, the T9 knows which rooms are in use so it can automatically focus on them. Intelligent motion detection algorithms help it tell the difference between someone passing through or spending time in a room, so your ideal comfort can efficiently follow you and your family from room to room over the course of your day. So, if the kids are doing homework or playing while you get dinner ready, everyone will be cozy — and when it’s time to gather, it can keep up.
SMART HOME INTEGRATION
It's easy to incorporate the T9 into your home system. Our partners integrate through the Works with Honeywell Home program so you can control your devices the way you want.
HONEYWELL HOME APP
Manage your Honeywell Home devices in one easy-to-use app, making it simple to control home comfort, monitor usage, and more — from anywhere.
Worry less. You’ll get alerts if the temperature rises or drops outside of your threshold and get reminders to change your air filter. Plus, your thermostat will switch to your preferred ‘away’ temperature when you leave — automatically.
REQUIRED: A C-Wire (common wire) is needed for 24 VAC power. If you do not have a C-Wire, then a C-Wire Adapter is provided.
If you currently have a Honeywell Home T-Series thermostat, your wiring may already be set to install the T9. Thanks to their shared wall mount, replacing an old T-Series thermostat with a new T9 is as simple as snap-off, snap-on. If you don't have a C-Wire, there's even an included adapter to cover that. For more installation information, check out the Honeywell T9 Installation Guide.
