Only qualified personnel should install and service the equipment. The installation, starting up, and servicing of heating, ventilating, and air-conditioning
equipment can be hazardous and requires specific knowledge and training. Improperly installed, adjusted or altered equipment by an unqualified person
could result in death or serious injury. When working on the equipment, observe all precautions in the literature and on the tags, stickers, and labels that
are attached to the equipment.

NOTICE
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:
Indicates a potentially hazardous situation which, if not avoided, could result in
death or serious injury.
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.
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 Responsible 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.
Symbio™™ 800700 Controller Overview
The Symbio™ 800700 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 RTU control panel.
The RTUunit 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 800 controller supports the following communication protocol options for
integration to either Trane or non-Trane control systems:
• BACnet TP
• BACnet Air-Fi
• BACnet IP
– Ethernet
– Wi-Fi
• Modbus RTU
• Modbus TCP
• LonTalk
For information pertaining to the integration of the Symbio 800 controller using either Modbus or
BACnet communication, refer to the integration guides specific to those applications.
Units of Measure
The communicated LonTalk data of the Symbio™ 700 controller will be passed in the factoryconfigured units of measure, inch-pound (I-P) by default. The Symbio 700 mobile application
allows the user to change and customize the Data Display Units Preferences.
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
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.

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 TP communications at 76,800 bps with a rotary address setting of 000.
Figure 1. Symbio™™ 800 rotary address and service tool port
Service Tool for Symbio™™ 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
).

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 Symbio 800 rotary addresses are not used with LonTalk communications.

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.

Appendix A. Arbitration
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
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. Arbitration method - full/auto
Figure 6, p. A–1, the arbitrator considers all possible sources of the provided data,
BAS-SVP039C-EN
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.
