Trane Link Zone Thermostat

Manufacturer Part Number: TZON2HUIA252ZA

The TZON2HUIA252ZA is a communicating zone thermostat with a display for Trane Link zoning systems. Its 7-inch diagonal color touchscreen provides zone temperature and relative humidity information while allowing users to adjust local setpoints. Heat, Cool, Auto, and Off zone modes are complemented by Auto, On, and Circulate fan selections. Temperatures can be shown in Fahrenheit or Celsius, and multiple zone temperature sensors can be averaged to provide the input used by the compatible zoning installation.

This four-wire communicating thermostat supports schedules, Permanent Hold, and one-touch Home, Away, and Sleep presets for everyday zone management. When enabled, users can view and adjust all zones, or access can be restricted to the assigned zone. Zone naming, display characteristics, and screensaver settings are adjustable. Outdoor temperature display requires Trane Home registration or a wired outdoor-temperature input, and software upgrades are delivered through the Link360 controller. The handbook identifies it as a Link zone device, not a standalone Wi-Fi thermostat.
