Tracer Summit controls — Interface
With The Trane Integrated Comfort
System (ICS)
Trane Chiller Plant Control
The Tracer Summit Chiller Plant Building
Management System with Chiller Plant
Control provides building automation
and energy management functions
through stand-alone control. The Chiller
Plant Control is capable of monitoring
and controlling your entire chiller plant
system.
Application software available:
• Time-of-day scheduling
• Demand limiting
• Chiller sequencing
• Process control language
• Boolean processing
• Zone control
• Reports and logs
• Custom messages
• Run time and maintenance
• Trend log
• PID control loops
And of course, the Trane Chiller Plant
Control can be used on a stand-alone
basis or tied into a complete building
automation system.
When the scroll CGWF chiller is used in
conjunction with a Trane Tracer
™
Summit system, the unit can be
monitored and controlled from a remote
location. The chiller can be controlled to
fit into the overall building automation
strategy by using time of day
scheduling, timed override, demand
limiting, and chiller sequencing. A
building owner can completely monitor
the chiller from the Tracer system, since
all of the monitoring information
indicated on the unit controller’s
microcomputer can be read off the
Tracer system display. In addition, all the
powerful diagnostic information can be
read back at the Tracer system. Best of
all, this powerful capability comes over a
single twisted pair of wires! The scroll
liquid chillers can interface with many
different external control systems, from
simple stand-alone units to ice making
systems.
A single twisted pair of wires tied directly
between the CGWF chiller and a Tracer
™
Summit system provides control,
monitoring and diagnostic capabilities.
Control functions include auto/stop,
adjustment of leaving water temperature
setpoint, compressor operation lockout
for kW demand limiting and control of
ice making mode. The Tracer system
reads monitoring information such as
entering and leaving evaporator water
temperatures and outdoor air
temperature. Over 60 individual
diagnostic codes can be read by the
Tracer system. In addition, the Tracer
system can provide sequencing control
for up to 25 units on the same chilled
water loop. Pump sequencing control
can be provided from the Tracer system.
Tracer ICS is not available in conjunction
the external setpoint capability.
