Product Details & Specifications

HVAC Depot Pro Tip

The Trane XL824 TCONT824AS52DC is designed for conventional 24-volt HVAC control systems and should not be confused with Trane's proprietary communicating thermostats.

Before installing the XL824, verify that the HVAC system uses compatible conventional thermostat wiring.

Recommended installation checks:

1. Confirm the HVAC equipment model and control system type.
2. Verify the system uses conventional 24 VAC thermostat controls.
3. Check thermostat wiring and available terminals.
4. Confirm the equipment's heating and cooling stage requirements.
5. Verify a compatible common wire (C-wire) connection is available.
6. Check the control transformer capacity.
7. Connect the thermostat to Wi-Fi or Ethernet for smart features.
8. Configure heating, cooling, and humidity settings.
9. Test all operating modes after installation.

HVAC Depot Pro Tip: The XL824 supports advanced features such as remote access, scheduling, and humidity management. However, it is not a direct replacement for proprietary communicating thermostats used with certain Trane variable-speed systems.

Important: Turn off HVAC system power before thermostat installation. Incorrect low-voltage wiring can damage the thermostat or HVAC control board.
