LonTalk Chiller Controls
LonTalk is a communications protocol developed by the Echelon™ Corporation. The LonMark™
association develops control profiles using the LonTalk communication protocol. LonTalk is a unit
level communications protocol.
LonTalk Communications Interface for Chillers (LCI-C) provides a generic automation system with
the LonMark chiller profile inputs/outputs. In addition to the standard points, Trane provides other
commonly used network output variables for greater interoperability with any automation system.
The complete reference list of Trane LonTalk points is available on the LonMark web site.
