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.
WARNING 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.

WARNING 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.

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.

WARNING
Proper Field Wiring and Grounding Required! Failure to follow code could result in death or serious injury. All field wiring MUST be performed by qualified personnel. Improperly installed and grounded field wiring poses FIRE and ELECTROCUTION hazards. To avoid these hazards, you MUST follow requirements for field wiring installation and grounding as described in NEC and your local/state/national electrical codes.

WARNING
Personal Protective Equipment (PPE) Required! Failure to wear proper PPE for the job being undertaken could result in death or serious injury. Technicians, in order to protect themselves from potential electrical, mechanical, and chemical hazards, MUST follow precautions in this manual and on the tags, stickers, and labels, as well as the instructions below:

Before installing/servicing this unit, technicians MUST put on all PPE required for the work being undertaken (Examples; cut resistant gloves/sleeves, butyl gloves, safety glasses, hard hat/bump cap, fall protection, electrical PPE and arc flash clothing). ALWAYS refer to appropriate Safety Data Sheets (SDS) and OSHA guidelines for proper PPE.

When working with or around hazardous chemicals, ALWAYS refer to the appropriate SDS and OSHA/GHS (Global Harmonized System of Classification and Labelling of Chemicals) guidelines for information on allowable personal exposure levels, proper respiratory protection and handling instructions.
If there is a risk of energized electrical contact, arc, or flash, technicians MUST put on all PPE in accordance with OSHA, NFPA 70E, or other country-specific requirements for arc flash protection, PRIOR to servicing the unit. NEVER PERFORM ANY SWITCHING, DISCONNECTING, OR VOLTAGE TESTING WITHOUT PROPER ELECTRICAL PPE AND ARC FLASH CLOTHING. ENSURE ELECTRICAL METERS AND EQUIPMENT ARE PROPERLY RATED FOR INTENDED VOLTAGE.

Overview

Purpose
The purpose of this document is to provide instructions for integrating the Symbio™ 800 controller into building automation systems. This document is targeted to system integrators and controls contractors.

Symbio™ 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.

Note: 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® MS/TP
BACnet Zigbee® (Air-Fi)®
BACnet IP
- Ethernet
- Wi-Fi
Modbus® RTU
Modbus TCP

LonTalk®

For information pertaining to the integration of the Symbio 800 controller using 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.

Important: 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.

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.

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 Figure 1, p. 6).

Connecting to the Symbio™ 800 Web Interface

Connect a laptop to the Symbio™ 800 controller using a USB cable.

On the laptop, open a web browser to http://198.80.18.1/
When the Symbio 800 page displays, click Log In.

Note: The Symbio 800 web interface can only be viewed using the USB connection. Ethernet port 1 and Ethernet port 2 will not allow access to the Symbio web server to meet IT security requirements.

BACnet® Protocol Configuration

To access the Symbio™ 800 Protocol Configuration page:

Connect to the Symbio 800 web interface.
On the left-hand navigation, click Installation.

Click Identification and Communications.
Click the Protocol Configuration tab.
Click Edit to change the Protocol Configuration settings. See the sections below for details on editing BACnet MS/TP, BACnet IP, and BACnet Air-Fi® protocols.

BACnet MS/TP Protocol Settings
The rotary address on the Symbio 800 controller sets the BACnet MS/TP MAC address. Each BACnet MS/TP device on the same TP link must have a unique MAC address. The valid range of BACnet MS/TP MAC addresses for the Symbio 800 is: 001–127.

Important: The Symbio 800 controller will disable BACnet MS/TP communications if the rotary address is 000!

Changing the rotary address will immediately take affect and does NOT require a power cycle to the Symbio 800 controller. The rotary address also sets the BACnet Device ID which gives a range of 1-127. All BACnet devices must have a unique BACnet Device ID. The Symbio 800 BACnet Device ID can also be manually changed using a web browser, the Tracer® SC+ system controller, or Tracer TU.

To configure the Symbio 800 for BACnet MS/TP protocol: (See the following figure for user interface locations for each step.).

Set the System Protocol drop-down to BACnet MS/TP.
Verify the Baud Rate (default is 76,800 bps). All BACnet MS/TP devices on an TP link must communicate at the same baud rate.

Verify the Current Device ID. To change the device ID, click Use Software Device ID and enter the desired device ID. The valid device ID range using a software device ID is 1–4194302 as defined by the BACnet standard.

The BACnet MS/TP communication wire is connected to the P1 Link. Observe wire polarity when connecting to the + and – terminals. The + terminals and the – terminals are internally connected. The second set of + and – terminals on the P1 Link are used to make it easier to wire the next BACnet MS/TP device in the daisy chain. Refer to the BACnet standard or BACnet MS/TP Wiring and Link Performance Best Practices and Troubleshooting guide BAS-SVX51*–EN for detailed information on TP wiring.

BACnet® IP (Ethernet or Wi-Fi connectivity)
The Symbio™ 800 controller can communicate BACnet IP using a standard Ethernet cable or using Wi-Fi (with the optional USB to Wi-Fi adapter). If using BACnet IP using a standard Ethernet cable, connect the Ethernet cable with RJ-45 connectors to Ethernet port 1 and the BACnet network. If using BACnet IP communication using Wi-Fi, the optional USB to Wi-Fi adapter should be connected to one of the USB ports.

Note: Use only Ethernet 1 connection or Wi-Fi adapter.

Manually Change Symbio™ 800 BACnet® Device ID
The rotary address on the Symbio 800 controller sets the BACnet Device ID which gives a range of 1-999. All BACnet devices must have a unique BACnet Device ID. The Symbio 800 BACnet Device ID can also be manually changed using a web browser or the Tracer® SC+ system controller.

Set the System Protocol drop down to BACnet IP.
Verify the current Device ID. To change the Device ID, click Use Software Device ID and enter the desired Device ID. Most installations will not need to manually change the BACnet Device ID.
Note: The valid Device ID range using a software Device ID is 1 – 4194302 as defined by the BACnet standard.

If using an Ethernet cable, set the Network Connection to Ethernet 1. If using the USB to Wi-Fi adapter, set the Network Connection to Wi-Fi.
Set the UDP Port to match the port number used by the BACnet IP network. The default is 47808.
Check the BBMD checkbox only if the Symbio 800 controller is the only BACnet IP device on the IP subnet.
- If a change to the BBMD checkbox was made, click Save and refresh the web browser. If BBMD functionality is enabled, the BDT setup button displays.
- If BBMD functionality is enabled, click BDT Setup to set up the BACnet Distribution Table (BDT).

Equipment-specific BACnet® points lists are available on trane.com product page.

Object Naming Conventions
The communicated points for the Symbio™ controllers are generally named according to their function. While many of the points are read-only, others include both read and write capability. The established naming convention helps to identify the capabilities of each point. For most points, the suffix identifies the capability according to the following definition. While there are some exceptions, the majority of the points have been defined according to these guidelines.

Suffix	Description
Status	Points with the Status suffix are defined as read-only. The status point reports the value being used by the controller.
Local	Points with the Local suffix are defined as read-only. The local point reports values associated with controller sensors, both wired and wireless. The local value may or may not be actively used by the controller, depending on the presence or absence of a communicated value (BAS). When both a local and communicated value exist, the communicated value is used.
Active	Points with the Active suffix are defined as read-only. Points designated as active are normally the result of the arbitration between a communicated value(BAS) and at least one value local to the equipment, such as a sensor or default setpoint. The active point reports the value being input to the controller.
Setpoint	Points with the Setpoint suffix are defined as either read-only or read/write. For BACnet®, the binary input, analog input and multi-state input points are all read-only. These setpoints report the value currently in use by the controller. The analog value, binary value and multi-state value points are all read/write. These points are provided for use by the building automation system (BAS). When used, these points are written internally to arbitration logic. This defines the interaction with hardwired points, editable software configuration points and the relinquish default value/state. Refer to the Appendix for additional information.
Input	Points with the Input suffix are defined as read-only. These points normally reflect the status of a sensor input, either hardwired or communicating wirelessly (Air-Fi®). However, the input point reflects the arbitrated result of the controller sensor input and a communicated value, if present. When both a controller sensor and communicated value exist, the controller will use and report the communicated value.
Arbitrator	Points with the “Arbitrator” suffix are to be used as read-only. The arbitrator prioritizes inputs from communicating points, hardwired points and stored defaults points. The priority array of the arbitration point displays each of the values provided, including the active status, indicating which of the input sources is being used. Refer to the Appendix for additional information.
BAS	Points with the BAS suffix are defined as read/write. These points are provided for use by the building automation system (BAS). When used, these points are written to arbitration logic. This defines the interaction with hardwired points, editable software configuration points and the relinquished default value/state. Refer to the Appendix for additional information.
Command	Points with the Command suffix are defined as read/write. These points are written to change the default behavior of the controller. Once written, these point values may be persisted.
Request	Points with the Request suffix are defined as read/write. These points are written to request a change the operating behavior of the controller.

Recycled Points

The Symbio™ 800 controller ships from the factory pre-configured for the specific unit application. The points of the communicated interface (BACnet®, Modbus®, or LonTalk®) vary based on the unit configuration. Only those points pertinent to that configuration are included in the interface.

BACnet Points List
Example: When the unit is configured for only two compressors, any points associated with compressors three and four are not be displayed on the Touch Screen interface or browser-based Web user interface. When configuration changes are made in the field, the points in the communication interface change accordingly to align with those features or user-added points.

Any of the factory-provided points can be removed from the communication interface through a feature known as recycling. When the user selects and deletes a factory point, that point is moved to Recycled Points and is removed from the interface. This feature offers technicians the ability to strategically provide only those interface points desired for a specific project or installation.

To remove a point from the interface:

On the left-hand navigation, select Points.
Each of the points are grouped by their native type (analog, binary or multi-state), and input, output, or value. Select the appropriate group at the top of the page.

Select one or more points from the list and select Actions… | Delete.

Note: User-created points cannot be recycled. Instead, when the user selects and deletes user-created points, those points are permanently removed from the controller. Should the user decide later that one or more of the deleted user points are needed, they will need to be recreated.

To restore recycled points:

Navigate to the Recycled Points tab on the Points page.
Select one or more points to be restored, then click Restore.
Once the restore process is complete, the restored points are moved back to the appropriate tab depending on point type. The recycled points also appear in the communicated interface once they are restored.

Modbus Protocol Configuration

To access the Symbio™ 800 Protocol Configuration page:

Connect to the Symbio™ 800 web interface.

On the left-hand navigation, click Installation.
Click Identification and Communications.
Click the Protocol Configuration tab.

View the existing Protocol Configuration settings.

Modbus Protocol Settings
The rotary address on the Symbio™ 800 controller sets the Modbus address, sometimes called a device ID. Each Modbus server controller on the same Modbus RTU link must have a unique address. The valid range of Modbus RTU server addresses for the Symbio™ 800 is: 001 – 247.

Important: Symbio™ 800 controller will disable Modbus RTU communications if the rotary address is 000! Changing the rotary address will immediately take affect and does NOT require a power cycle to the Symbio™ 800 controller.

Set the Communication Protocol drop down to Modbus RTU.
The rotary dial setting field shows the physical setting of the rotary dials on the Symbio™ 800. The address field shows the Modbus RTU address. The Modbus RTU address will match the rotary dial setting unless the Use Software address option is used. The recommendation is to change the Modbus address using the physical rotary dials on the Symbio™ 800 controller.

Verify the baud rate (default is 19200 bps), parity (default is Even), and stop bits (default is 1).All Modbus RTU devices on a link must communicate using the same communication parameters.

Modbus Wiring
The Modbus RTU communication wire is connected to the P1 Link. Observe wire polarity when connecting to the + and – terminals. The + terminals and the – terminals are internally connected. The second set of + and – terminals on the P1 Link are used to make it easier to wire the next Modbus RTU device in the daisy chain. Refer to the TIA/EIA 485 standard for detailed information on Modbus RTU wiring.

Modbus TCP (Ethernet)

The Symbio™ 800 controller can communicate Modbus TCP using a standard Ethernet cable. Connect an Ethernet cable with RJ-45 connectors to Ethernet port 1 and the IP network. The Symbio™ 800 controller does not support the optional Wi-Fi module with Modbus TCP communications. The rotary address on the Symbio 800 controller is not used with Modbus TCP communications. Ethernet Port 2 is reserved for the optional touch screen display.

Set the System Protocol drop down to Modbus TCP.
Click the IP Configuration tab to set the IP address of the Symbio™ 800 controller.

Click Edit.
Setup the Ethernet 1 port to either ‘Obtain an IP addresss Automatically using DHCP’ or use a static IP address by manually entering the IP address, subnet mask, and default gateway. The IP address information is typically provided by the local IT administrator.
Set the Preferred IP Interface to Ethernet 1.

Set up the DNS section if using a Domain Name System server to identify the Symbio™ 800 controller by host name.

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 Figure 25, 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.

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.
