Introduction
Read this manual thoroughly before operating or servicing this unit
Warnings, Cautions, and Notices
Safety advisories appear throughout this manual as required Your personal safety and the
proper operation of this machine depend upon the strict observance of these precautions
The three types of advisories are defined as follows:
WARNING
Indicates a potentially hazardous situation which, if not avoided, could result in
death or serious injury.
CAU TION
Indicates a potentially hazardous situation which, if not avoided, could result in
minor or moderate injury. It could also be used to alert against unsafe practices.
NOTICE
Indicates a situation that could result in equipment or property-damage only
accidents.
Important Environmental Concerns
Scientific research has shown that certain man-made chemicals can affect the earth’s naturally
occurring stratospheric ozone layer when released to the atmosphere In particular, several of the
identified chemicals that may affect the ozone layer are refrigerants that contain Chlorine,
Fluorine and Carbon (CFCs) and those containing Hydrogen, Chlorine, Fluorine and Carbon
(HCFCs) Not all refrigerants containing these compounds have the same potential impact to the
environment Trane advocates the responsible handling of all refrigerants-including industry
replacements for CFCs and HCFCs such as saturated or unsaturated HFCs and HCFCs
Important Responsi le Refrigerant Practices
Trane believes that responsible refrigerant practices are important to the environment, our
customers, and the air conditioning industry All technicians who handle refrigerants must be
certified according to local rules For the USA, the Federal Clean Air Act (Section 608) sets forth
the requirements for handling, reclaiming, recovering and recycling of certain refrigerants and
the equipment that is used in these service procedures In addition, some states or municipalities
may have additional requirements that must also be adhered to for responsible management of
refrigerants Know the applicable laws and follow them

Overview
Purpose
The purpose of this document is to provide instructions for integrating the Symbio™800700
controller into Non-Trane building automation systems This document is targeted to system
integrators and controls contractors
Sym io 800 Controller Overview
The Trane Chiller includes the Symbio 800 controller The controller has been installed,
programmed, wired, commissioned, and tested in the factory prior to shipment While some
sensors and end devices are normally wired in the field, nearly all other wiring is factory-
provided Power for the controller is provided and connected from within the chiller control
panel
The chiller and associated controller can be applied as standalone or as part of a building
automation system
NNoottee:: For communicating applications to third-party control systems, network communication
wiring must be provided by others.
Communication Options
The Symbio™700800 controller supports the following communication protocol options for
integration to either Trane or Non-Trane control systems:
• BACnet MS/TP
• BACnet IP
• BACnet Zigbee (Air-Fi)™
• BACnet/IP
–Ethernet
–Wi-Fi
• Modbus RTU
• Modbus TCP
• LonTalk
For information pertaining to the integration of the Symbio™700800 controller using either
Modbus or LonTalk communication, refer to the integration guides specific to those applications
Units of Measure
The communicated data of the Symbio™800 controller will be passed in the factory-configured
units of measure, either inch-pound (I-P) or the International System of Units (SI) The units of
measure are selected as part of the unit order (the default selection is normally I-P) Should the
units of measure need to be changed in the field, contact your local Trane representative
The Symbio 800 controller provides a browser-based user interface for USB connection to the
controller One of the tools provided with that interface allows the user to change and customize
the Data Display Units Preferences
IImmppoorrttaanntt:: These adjustable settings are applied only to the units of measured displayed in the
web interface, not the communicated interface.
Regardless of the communicated (system) units of measure, the user may change the displayed
units of measure on their smart device These user preference units of measure are independent
of the communicated units

6BAS-SVP046A-EN
Communication Setup and Configuration
The Symbio™800 controller can be factory ordered with a specific protocol configuration and
rotary address setting If communication options were not specified, the Symbio™800 controller
will be setup for BACnet MS/TP communications at 76,800 bps with a rotary address setting of
000
Figure 1. Sym io™™ 800 rotary address and service tool port
Service Tool for Sym io™™ 800 Configuration
The service tool used to modify the Symbio™800 controller is a standard web browser The
Symbio™800 webpage is accessed by using a standard USB type A/B cable Connect the USB
cable between a laptop and the service tool port on the Symbio™800 controller (shown in Figure
1, p 6)

BAS-SVP046A-EN 7
Connecting to the Sym io™™ 800 We Interface
1 Connect a laptop to the Symbio™800 controller using a USB cable
2 On the laptop, open a web browser to http://198 80 18 1/
3 When the Symbio™800 page displays, click LLoogg IInn
Figure 2. Sym io™™ 800 log in screen
NNoottee:: The ymbio ™ 800 web interface can only be viewed using the U B connection. Ethernet
port 1 and Ethernet port 2 will not allow access to the ymbio
™ web server to meet IT
security requirements.

NNoottee:: There are no LonTalk communication parameters to edit.
LonTalk Protocol Settings
The Symbio 800 controller supports LonTalk communications with the optional LonTalk module
The LonTalk module is din rail mounted and is connected to the Symbio 800 controller using
USB
NNoottee:: The ymbio 800 rotary addresses are not used with LonTalk communications.

BAS-SVP046A-EN 9
Figure 5. LonTalk protocol configuration
1 Verify the LonTalk adapter connection status is CCoonnnneecctteedd If the adapter connection status is
another state, verify the LonTalk adapter is connected to a Symbio 800 USB port
2 Verify the Link Status is OOnnlliinnee If the Link Status is set to a different state, LonTalk network
management software such as Trane’s Rover software is needed to set the Link status to
Online
3 The Service Pin button will send a service pin message to the LonTalk network A service pin
will broadcast the Neuron ID to the LonTalk network so a LonTalk network management tool
can find a device and set its Domain, Subnet, Node address
LonTalk communication wire is connected to the LonTalk adapter LonTalk does not require wire
polarity but it is recommended that wire polarity be observed Refer to the LonTalk standard for
detailed information on LonTalk wiring
All LonTalk devices must have a unique DSN address and must have the same Domain value
The Symbio 800 LonTalk adapter ships on the zero-length domain so it can be easily discovered
by LonTalk network managers and tools

BAS-SVP046A-EN A–1
Appendix A. Ar itration
The Symbio™800 controller includes arbitration logic for several points For each read/write
point designated as “BAS”, an associated “Arbitration” point determines the behavior of that
communicated data compared to the local hardwired (or wireless) sensor and a default value
As shown in Figure 6, p A–1, the arbitrator considers all possible sources of the provided data,
including Building Management Systems (BMS), local, and default Each potential source is
defined at a pre-determined, fixed priority When the arbitration method is selected as full/auto,
the BMS value is used instead of the local or default values
The point designator with the arbitrator suffix includes the full priority array, allowing the user to
see the value associated with all potential sources considered in the logic The active point
reflects the result of the arbitration logic
Because the arbitrated points are normally associated with sensors, the default value is invalid,
meaning the value must be provided either by the BMS or the local sensor
Figure 6. Ar itration method - full/auto
When the Arbitration Method is selected as local, the BMS value is ignored and local value is
used instead Though the arbitration logic still considers all inputs, any values sent by the BMS
are effectively ignored
