Trane Open Solution

Today’s building professionals demand products that enable them to design and install open solutions. In response, Trane offers equipment, controllers, and systems that fully support open protocols. More importantly, Trane offers the system integration knowledge to combine products and services into answers that meet a variety of needs. As an HVAC leader, Trane knows and understands HVAC equipment. This knowledge and expertise make Trane uniquely qualified to control equipment for the most efficient operation within the building automation system. While some applications demand open communication, many building owners find an all Trane system best meets their needs. Trane controls and HVAC components are designed to work together, resulting in easier commissioning and start-up. In ongoing operation, there is a single source available for parts and service. With support for standard industry protocols built in, a total Trane system is still open for auxiliary systems and future building options. Whether a specific application calls for a single source supplier, or complex system integration, Trane can deliver a solution.

Communication Interface for Chillers (LCI-C)

The optional LCI-C, available factory installed or field retrofitted, is an integrated communication board that enables the chiller controller to communicate over a LonTalk network. While monitoring alarms and status, the LCI-C is capable of controlling chiller setpoints and operating modes. The Trane LCI-C adds, to the standard chiller profile, an additional set of points to satisfy a broader range of system interoperable applications.

These added points, or open extensions, build on the standard LonMark ® chiller profile.

The LCI-C is certified to the LonMark Chiller Controller Functional Profile 8040 version

1.0 and follows LonTalk FTT-10A free topology communications.
