7 Best Thermostats for Trane of 2026

The Trane XL1050 isn’t just a thermostat—it’s the command center for your home’s comfort ecosystem. With its 7-inch touchscreen and native zoning control, it delivers an unmatched level of precision for multi-zone Trane systems, giving you granular control over every corner of your home.

The lack of Wi-Fi means no remote access or app control, limiting its appeal in today’s connected homes.

Compared to the XR202, the TCONT302 offers a modern touchscreen and greater staging support, making it a natural step up for those upgrading from basic programmables. But against the XL824, it falls short by missing Wi-Fi, smart features, and Nexia integration. It’s best for users who want Trane reliability and touchscreen ease without the complexity (or cost) of a full smart thermostat—perfect for value-focused upgrades where local control is enough.

The Trane XL824 Nexia Control is a smart thermostat sleeper hit—offering nearly all the intelligence of its pricier siblings at a fraction of the cost. With full Nexia home integration, it lets you control your HVAC alongside lights, locks, and sensors from a single app, turning your thermostat into a true home automation hub. Its 4.3” color touchscreen is bright and responsive, and support for 5 heat stages and 2 cooling stages ensures compatibility with advanced Trane systems, including dual-fuel and variable-speed units.

In practice, it delivers smooth scheduling, remote access, and reliable connectivity via Wi-Fi or Ethernet. The interface is straightforward, though slightly dated compared to modern smart thermostats. Like other communicating models, it only works with Trane and American Standard 3-wire systems, so it’s not a universal replacement. But for those within the ecosystem, it offers exceptional value—especially when compared to the nearly identical B0DM6PR56G model, which costs significantly more for the same functionality.

Positioned as the best value Wi-Fi model, it outperforms the TCONT302 by adding remote control and smart automation, while undercutting the XL850 on price without sacrificing core intelligence.
