The Honeywell Home THX321WFS2001W/U T10 Pro WIFI RedLink Thermostat w/ Room Sensor is a good WIFI thermostat option for users wanting compatibility with the robust and powerful Total Connect 2.0 platform. This powerful device offers a clean UI and plenty of heating and cooling features.

Like pretty much any smart thermostat, the Honeywell Home T10 Pro connects with the building's HVAC system. You should make sure to cut power at the circuit breaker before installing. The installation itself is made simple using the straightforward UWP mounting system from Honeywell Home. The UWP mounting system is the same across any Honeywell T-Series Thermostat, making it easy to swap models if needed.

Once you have the Honeywell Home T10 Pro Thermostat installed, you can get it connected to a local WIFI network. This will allow you to control it through the convenient Honeywell Home App on your phone. An integration between Honeywell Home and Total Connect 2.0 is also available to expand upon the ways you can use the thermostat. No RedLink gateway is required as part of the setup process. Once paired with Total Connect 2.0, you will be able to control your Honeywell Alarm System and your T10 Pro Thermostat from the same great platform!

The Honeywell Home App offers some nice capabilities in using your T10 Pro Thermostat. You can establish rules and temperature settings based on a schedule, and based on GeoFencing location. For example, you can have the thermostat begin heating or cooling your home once you are a certain distance away from home so that your house is comfortable by the time you arrive. This is great for ensuring personal comfort, while also keeping energy costs low. The thermostat is Energy Star Certified, so you know that you can count on it for savings. It is also compatible with most demand response programs that can be used to save you even more money.

Honeywell Home supports various smart home assistant integrations to give you even more options for controlling your T10 Pro Thermostat. Some of the integrations include Amazon Alexa and Google Assistant. Just pair your Honeywell Home account with your compatible smart home assistant, and enjoy new ways to provide heating and cooling commands through spoken voice. Local control will also remain possible, as the T10 Pro has a big, prominent display screen that makes it easy to operate the thermostat while on-site. The screen is backlit to make nighttime operation easy.

Included with this thermostat is a special Room Sensor that can communicate up to 200 nominal feet away from the T10 Pro. The Room Sensor is specifically designed to sense temperature, humidity, and motion, so that heating and cooling adjustments can be automatically made on the T10 Pro Thermostat. A maximum of twenty (20) Room Sensors can be connected with the T10 Pro, though this bundle only includes one (1) to get you started. More must be purchased separately. The Room Sensor is also Energy Star Certified.
