(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 air-cooled Series R
™
70-125 ton
chiller is used in conjunction with a Trane
Tracer
™
Summit system, the unit can be
monitored and controlled from a remote
location. The air-cooled Series R
™
70-125
ton 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 air-cooled Series
R
™
70-125 ton 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! Air-

70-125 ton chillers can
interface with many different external
control systems, from simple stand-
alone units to ice making systems. Each
unit requires a single-source, three-
phase power supply and a 115V/60Hz,
220V/50Hz power supply. The added
power supply powers the evaporator
heaters.
A single twisted pair of wires tied directly
between the air-cooled Series R
™
70-125
ton 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 with the remote display or
the external setpoint capability.
