Trane Symbio™ 700 Controller User Guide

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.
CAUTION: 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.

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.

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.

Follow EHS Policies!

Failure to follow instructions below could result in death or serious injury.

All Trane personnel must follow the company's Environmental, Health and Safety (EHS) policies when performing work such as hot work, electrical, fall protection, lockout/tagout, refrigerant handling, etc. Where local regulations are more stringent than these policies, those regulations supersede these policies.
Non-Trane personnel should always follow local regulations.

Symbio™ 700 Controller Overview

The Symbio™ 700 controller is a factory installed, programmed control system providing digital control and protection of the equipment. It offers equipment and control configurations that can be used with light commercial packaged equipment. This control system consists of the Symbio 700 main controller and up to four option modules used to provide optional functional operation. A system may or may not include option modules, depending on the configuration of the equipment.

Remote connectivity: Standard, remote access and monitoring, providing troubleshooting support without a site visit via Trane Connect.

Basic vs. Advanced Controller

The Symbio 700 has two models:

Basic controller: provides advanced troubleshooting capabilities via on-board user interface and Symbio Service and Installation Mobile app but does not provide communication, programming, or remote access.
Advanced controller: provides full controller capacities that include advanced troubleshooting, communications, programming, and remote access. The advanced controller is a purchased feature.

The unit model number, Symbio 700 local user interface, or the Symbio Service and Installation Mobile app can be used to determine which version of the controller is in the equipment. To upgrade from a Basic controller to an Advanced controller, the Basic Symbio 700 must be replaced with an Advanced Symbio 700, which is available through Trane Service Parts.

Symbio Service and Installation Mobile Application

The Symbio Service and Installation mobile app provides advanced configuration, setup, status updates, alarms, and service capabilities for the Symbio 700 controller via Bluetooth connection. The Symbio 700 can connect to mobile devices that support BLE version 4.2 and higher. Only one connection is allowed at a time to prevent another user from connecting to the system while it is already in use. If a connection is lost, whether accidental or purposeful, a timer is used to prevent the controller from being locked by a user that does not disconnect the controller in a preferred manner.

The Symbio Installation and Service tool is required to view and edit the following:

Equipment configuration
Historical alarms
Firmware updates
Backup and restore
Building Automation System configuration

For more detailed information on the Symbio Service and Installation Mobile Application, refer to the Quick Start Guide for Symbio Service and Installation - BAS-SVN043*-EN.

9. Press the check mark [Check Icon] on the Symbio 700 on-board keyboard/display to complete the pairing.

When the LED light is a solid blue and the display reads Bluetooth Connected, the Bluetooth pairing and connection is complete.

Troubleshooting

Issue	Description
Smart device requirements not met	Apple iPhone (iOS V10; iPhone 6 or later required) Android (V5.0 Lollipop or later; a device with Bluetooth V4.2 or later required) Note: It is not possible to check what Bluetooth connectivity version is installed on an Android device, as it does not appear in Settings.
Multiple users attempting to connect to the controller via Bluetooth	Only one user can connect to the Symbio 700 controller via Bluetooth. If the blue light is solid, another user is connected to the controller.
Device outside of Bluetooth range limits	Bluetooth has physical range limitations. A user can lose connectivity if too far away from the controller and will need to re-access connectivity from the Units List page.
Exceeded limit of equipment pairings	The app only allows 10 saved pairings per device. Android devices will auto delete the oldest pairing. If auto delete fails, you can manually delete pairings. iOS users must manually delete pairings through Settings.
Smart device unpaired or disconnected from controller	Pressing the Bluetooth button on the controller while connected will disconnect the controller from the smart device. Cycling power to the controller, a firmware update, or a restore/start controller will disconnect the Bluetooth connection. Equipment shutdown will disconnect the Bluetooth connection.
