🛠️ HVAC Depot Pro Tip

The D4271C is the 4 Heat / 2 Cool commercial model without the additional humidity/dehumidification features of the D4272C. If the application requires humidity management, verify whether the D4272C is the appropriate control instead.

Also, the D4271C is WiFi capable, not WiFi-equipped out of the box. A compatible optional WiFi module is required to add wireless connectivity.

Before ordering, verify the equipment's heating/cooling stages, conventional vs. heat-pump configuration, thermostat wiring, and accessory requirements.

Equipment / Model Compatibility

The Daikin D4271C is designed for compatible Daikin light-commercial equipment, including select:

  • Packaged air conditioners

  • Packaged gas/electric systems

  • Packaged heat pumps

  • Commercial split air conditioners

  • Commercial split heat pumps

  • Multi-stage commercial HVAC systems

  • 3–25 ton compatible applications

Exact compatibility should be verified using the complete Daikin equipment model and system configuration.
