Tracer SC
TheTracer SC system controller acts as the central coordinator for all individual equipment devices
on aTracer building automation system.TheTracer SC scans all unit controllers to update
information and coordinate building control, including building subsystems such as VAV and
chiller water systems. With this system option, the full breadth ofTrane’s HVAC and controls
experience are applied to offer solutions to many facility issues.The LAN allows building operators
to manage these varied components as one system from any personal computer with web access.
The benefits of this system are:
• Improved usability with automatic data collection, enhanced data logging, easier to create
graphics, simpler navigation, pre-programmed scheduling, reporting, and alarm logs.
• Flexible technology allows for system sizes from 30-120 unit controllers with any combination
of LonTalk
®
or BACnet
®
unit controllers.
• LEED certification through site commissioning report, energy data collection measurement,
optimizing energy performance, and maintaining indoor air quality.
Energy savings programs include: fan pressure optimization, ventilation reset, and chiller plant
control (adds and subtracts chillers to meet cooling loads).
