Well Worth the Investment

Was never favorably impressed with the Bryant Thermostat that came with the new home. Last home had a Honeywell that I selected for the (basic) features in the early 90s and liked it. Fast forward, was looking at new ones and noticed the extensive features in the X8S (which are best found reading the installation and user manual). One feature is the connection to a video doorbell. After research decided on the Honeywell Resideo over the Ring doorbell. I absolutely love the combination; the quality, looks, feel and ease of configuring online. The idle display is elegant and informative, video doorbell display is great and controls easy to use. So happy that I just ordered two more for the rest of the house. Great company that I have come back to many times over the years. Yes, I do recommend this product.

Awesome unit

This is a great thermostat. I bought this after a referral from a co worker and it has exceeded my expectations. I had a nest before and the programming and app on this is far superior

Product FAQs

What makes the X8S a "Smart" thermostat compared to older Wi-Fi models?

The X8S is Matter Certified, meaning it offers seamless compatibility across major smart home platforms like Amazon Alexa, Google Assistant, and Apple Home. It also features Smart Sensing occupancy detection, which automatically adjusts your heating and cooling based on whether people are home, maximizing both comfort and energy savings.

Can I see who is at my door using this thermostat?

Yes. One of the standout features of the X8S is its video integration. When paired with compatible First Alert or Ring video doorbells, you can view a live stream and speak to visitors directly from the thermostat's 5 inch touchscreen display.

Does it require a C-Wire for installation?

Yes. Because of its high-resolution color touchscreen and advanced Wi-Fi features, the X8S is a hardwired device that requires a C-Wire (Common Wire) for power. It is compatible with most modern HVAC systems, including up to 4 Heat/2 Cool heat pump systems and up to 3 Heat/4 Cool conventional systems.

How does the X8S help manage indoor air quality?

Beyond just temperature, the X8S provides precision Indoor Air Quality (IAQ) management. It allows you to monitor and control humidity and ventilation systems directly. It also provides automated alerts for filter changes and system health to ensure your home environment remains healthy.

What are the benefits of the included wireless room sensor?

The wireless room sensor allows you to prioritize the temperature of a specific room, such as a nursery or a home office, rather than relying only on the thermostat’s location in a hallway. This helps eliminate hot and cold spots throughout your home and ensures the rooms you are actually using are kept at your preferred comfort level.
