The Trane XL900 features the ComfortLink II communicating technology, which connects all key components so the system automatically charges, configures, and calibrates for optimal performance. When the optional Telephone Access Module (TAM) is added, you can conveniently adjust settings and receive system updates anywhere by phone. In addition to the benefits of the precise calibration and maintenance alerts of the communicating system, materials for all components are tested again and again for long-lasting performance and reliability. A clear, menu-driven setup makes programming quick and easy.
