Optional Control and Output Circuits
Install various optional wiring as required by the
owner’s specifications (refer to “System Control Circuit
Wiring (Field Wiring),” p. 37).
Schematic Wiring Drawings
Please refer to the submittals and drawings that
shipped with the unit. Additional wiring drawings for
Agility™ chillers are available from your local Trane
office.
Adaptive Frequency Drive
The Trane TR200 Adaptive Frequency™ Drive (AFD) is
an electronic motor controller that converts alternating
current (AC) mains input into a variable AC waveform
output. The frequency and voltage of the output are
regulated to control the motor speed or torque. The
TR200 drive includes the following features:
• Soft start to minimize inrush current
• Improved harmonic mitigation with direct current
(DC) link reactor
• Integrated power fuse
• Graphical liquid-crystal display (LCD) keypad
• Unit-mounted with factory pre-wiring
• “Trane Drive Utility” for configuration and tracking

Agency for assistance.
Communications Interface
LonTalk Interface (LCI-C)
UC800 provides an optional LonTalk® Communication
Interface (LCI-C) between the chiller and a Building
Automation System (BAS). An LCI-C LLID shall be used
to provide “gateway” functionality between a
LonTalk® compatible device and the Chiller. The
inputs/outputs include both mandatory and optional
network variables as established by the LONMARK®
Functional Chiller Profile 8040.
NNoottee:: For more information, refer to Hardware and
Software Installation Guide: LonTalk
Communication Interface for Trane Chillers with
Tracer AdaptiView Control (ACC-SVN100*-EN).
BACnet Interface (BCI-C)
Optional BACnet® Communication Interface for
Chillers (BCI-C) is comprised of a Tracer® UC800
controller with interface software. It is a non-
programmable communications module that allows
units to communicate on a BACnet® communications
network.
MODBUS Remote Terminal Unit
Interface
Modicon Communication Bus (MODBUS®) enables the
chiller controller to communicate as a slave device on a
MODBUS® network. Chiller setpoints, operating
modes, alarms and status can be monitored and
controlled by a MODBUS® master device.
