BACnet Interface
BACnet
®
interface capabilities are available, with communication link via single twisted-pair wiring
to a factory-installed and tested communication board.
Required features:
• BACnet Interface (selectable option with chiller)
BACnet is a data communication protocol for building automation and control networks developed
by American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE).
LonTalk LCI-C Interface
LonTalk
®
(LCI-C) communications capabilities are available, with communication link via single
twisted-pair wiring to factory-installed, tested communication board.
Required features:
• LonTalk/Tracer Summit™ Interface (selectable option with chiller)
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 L
ONMARK 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 ofTrane LonTalk points is available on the L
ONMARK web site.
Trane controls or another vendor’s system can use the predefined list of points with ease to give
the operator a complete picture of how the system is running
Tracer Summit
The chiller plant control capabilities of theTraneTracer Summit building automation system are
unequaled in the industry.Trane’s depth of experience in chillers and controls makes us a well-
qualified choice for automation of chiller plants using air-cooled CGAM chillers. Our chiller plant
automation software is fully pre-engineered and tested.
Required features:
• LonTalk/Tracer Summit Interface (selectable option with chiller)
• Building Control Unit (external device required)
Energy Efficiency
• Sequences starting of chillers to optimize the overall chiller plant energy efficiency
– Individual chillers operate as base, peak, or swing based on capacity and efficiency
– Automatically rotates individual chiller operation to equalize runtime and wear
between chillers.
– Evaluates and selects the lowest energy consumption alternative from an overall
system perspective.
Regulatory Compliance Documentation
• Gathers information and generates the reports mandated in ASHRAE Guideline 3.
Easy Operation and Maintenance
• Remote monitoring and control
• Displays both current operation conditions and scheduled automated control actions
• Concise reports assist in planning for preventative maintenance and verifying performance
• Alarm notification and diagnostic messages aid in quick and accurate troubleshooting
