The Tracer Communication Interface for LonTalk® for the IntelliPak™ Unit Controller (LCI-I) enables a Packaged Rooftop, Commercial Self-Contained, or Fresh-Air unit to communicate over a LonTalk network. The LCI-I builds on the standard LonMark® Space-Comfort Controller and Discharge-Air Controller profiles with open extensions by adding additional points to satisfy a broader range of system-interoperable applications. Available as a factory-installed option or a field retrofit kit, the LCI-I is a pre-configured, factory-commissioned, highly integrated unit-control module that provides accurate & reliable control and equipment protection. Factory commissioning helps ensure the highest-level of quality and customer satisfaction.
