Controlling your home comfort has never been easier than with Trane's Link technology. Trane Link Zoning allows homeowners to create up to 6 zones in their homes and set a unique temperature in each, all via the Trane Home mobile app. Whether you'd rather it be cool upstairs and warm downstairs, or toasty in the living room and chilly in the kitchen, Trane Link technology can help. All you need to do is set your zones and control them with the click of a few buttons from any mobile device or desktop.
