Turn your home's temperature management into a tool for energy savings and comfort. The Trane XL824 Nexia Control is built for homeowners with Trane or American Standard 3-wire communicating systems. It replaces models like ACONT824AS52DA and XL824, offering precise control over up to 5 heat and 2 cool stages.
The 4.3-inch color touchscreen shows your thermostat at a glance. You can adjust settings from across the room or use the Nexia app while away. Wi-Fi or Ethernet connectivity keeps you connected, and the system learns your schedule to optimize energy use. One evening, you can tweak the temperature from bed after noticing the forecast shifted. The display makes it easy.
This isn't for standard wired systems. It's designed specifically for communicating setups. If you're upgrading from an older communicating thermostat, you'll appreciate the responsive interface and the way it works with dual fuel or conventional systems. Save on heating and cooling bills without sacrificing comfort.
