SAFETY WARNING
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.

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 that, if not avoided, could result in death or serious injury.
CAUTION Indicates a potentially hazardous situation that, 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.
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.
WARNING
Follow EHS Policies! Failure to follow the 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.

Mobile Application
The Symbio™ Service and Installation mobile app provide 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 Service and Installation app is required to configure the following:
• BACnet® over ZigBee® (Air-Fi® Wireless)
• BACnet IP
• BACnet MS/TP
• LonTalk

Thermostats and Zone Sensors
Thermostats

Customers occasionally require operation with a conventional thermostat rather than a zone sensor. Non-Trane building controllers typically provide an interface to HVAC equipment based on a conventional thermostat interface. Units applied with this type of controller need to accept conventional thermostat inputs. Conventional thermostat signals represent direct requests for unit functions. This function provides inputs for the thermostat signals and processing to enhance reliability and performance. Compressor protection and reliability enhancement functions (HPC, LPC, minimum On/Off timers, etc.) all operate the same whether applied with zone sensors or a conventional thermostat. Logic is also provided to cause appropriate unit functions when inappropriate thermostat signals are provided. Simultaneous calls for heating and cooling will be ignored, and the fan will be turned on with a call for heating or cooling even if the fan request is not detected. If the thermostat is immediately changed from a heating to a cooling call or vice versa, there will be a delay before the new mode will initiate.

O (reversing valve during cooling) Reversing valve in cool mode Y1 + O (first stage cooling) Compressor 1 run

Zone Sensors
A 10k ohm resistance type 2 thermistor can be wired to terminals J19-1 and J19-2 as input for space temperature.
Averaging
In some applications, 1 zone sensor does not give a good representation of zone temperature. The internal thermistors, 10K ohm resistance @ 25C/77F, can be wired as shown below in order to provide an average input to the J19-1 and J19-2 terminals
Figure 6. Zone sensors

Communication Protocols
BACnet (ANSI/ASHRAE Standard 135-2016)
The Symbio 700 controller supports communication using BACnet MS/TP, BACnet IP, or BACnet/ Zigbee (Air-Fi™ Wireless). This allows the controller to communicate with most building automation systems. For more information on this protocol, see BACnet Integration to Odyssey Units with Symbio 700 Controls (ACC-SVP001).
LonTalk
The Symbio 700 Controller supports communication using LonTalk when the Tracer USB LonTalk Module is installed. This allows the controller to communicate with most building automation systems. For more information on this protocol, see LonTalk Integration to Odyssey Units with Symbio 700 Controls (ACC- SVP002).
