🛠️ HVAC Depot Pro Tip

The TCONT203AS42MADPL belongs to the Trane XR203 thermostat family. When replacing an existing thermostat, do not match by appearance or the XR203 name alone.

Verify:

  • Complete thermostat part number
  • Number of heating stages
  • Number of cooling stages
  • Conventional system vs. heat pump
  • Auxiliary and emergency heat requirements
  • Dual-fuel configuration
  • Existing thermostat wiring
  • HVAC control voltage

Also, do not confuse this thermostat with Trane's communicating controls. A communicating Trane HVAC system may require a specific communicating thermostat or system controller.

Equipment / Model Compatibility

The Trane TCONT203AS42MADPL XR203 is intended for compatible residential HVAC applications, including:

  • Trane air conditioners
  • Trane heat pumps
  • Trane gas furnaces
  • Gas/electric systems
  • Electric heating systems
  • Oil heating systems
  • Select dual-fuel systems
  • Multi-stage HVAC systems
  • Residential split systems

For exact equipment compatibility, verify the indoor model, outdoor model, system staging, and thermostat wiring before ordering.
