🛠️ HVAC Depot Pro Tip

The TCONT724AS42DA XL724 is a 24V HVAC thermostat and should not be confused with Trane's LINK360 communicating system controls.

Before ordering the XL724, verify:

  • Existing thermostat wiring
  • 24V control requirements
  • Number of heating stages
  • Number of cooling stages
  • Conventional AC vs. heat pump
  • Dual-fuel configuration
  • Common-wire availability
  • Variable-speed blower requirements
  • Humidity-control requirements
  • Indoor and outdoor equipment compatibility

The BK/PWM output is particularly important on compatible variable-speed systems because it can provide enhanced blower airflow control.

Equipment / Model Compatibility

The Trane TCONT724AS42DA XL724 is designed for compatible 24V residential HVAC systems.

Typical applications include:

  • Trane air conditioners
  • Trane heat pumps
  • Trane gas furnaces
  • Gas/electric systems
  • Dual-fuel HVAC systems
  • Compatible variable-speed indoor equipment
  • Residential split systems
  • Multi-stage heating and cooling equipment

The thermostat supports configurations of up to 4 stages of heating and 2 stages of cooling.

Always verify the complete indoor unit, outdoor unit, and existing control configuration before ordering.
