Trane Symbio 700 Manual

Overview

Purpose

The purpose of this document is to provide instructions for integrating the Symbio™ 700 controller into building automation systems. This document is targeted to system integrators and controls contractors.

Symbio™ 700 Controller Overview

The Symbio™ 700 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 control panel.
The unit 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™ 700 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)®
• Modbus® RTU
• Modbus TCP
• LonTalk®

For information pertaining to the integration of the Symbio 700 controller using LonTalk communication, refer to the integration guides specific to those applications.

Units of Measure

The communicated data of the Symbio™ 700 controller can be changed from inch-pound (IP) to the international system (SI) if desired. This can be done by using the Symbio™ Service and Installation app or the Onboard Display.
Regardless of the communicated (system) units of measure, the user may change the displayed units of measure the mobile app or Onboard Display. These user preference units of measure are independent of the communicated units.

Communication Setup and Configuration

Depending on the protocol and associated settings ordered from the factory, some changes may be required during equipment start-up. These can be made using the mobile app or onboard display protocol settings and/or IP settings in the Symbio™ controller.

Mobile App

The Trane Symbio™ Service and Installation mobile app is required to setup, edit, and confirm the communication protocol and associated settings.
The free download of Trane Symbio Service and Installation mobile app is available on the App Store® for iOS, and on Google Play® for Android™.

BACnet MS/TP Protocol Setup

The Symbio™ 700 controller rotary address sets the BACnet® MS/TP MAC address. Each BACnet® MS/TP device on the same MS/TP link must have a unique MAC address. The valid range of BACnet® MS/TP MAC addresses for the Symbio™ 700 is 001–127.
Changing the rotary address will immediately take effect and does NOT require a power cycle to the Symbio™ 700 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 Device ID can be edited using the mobile app or Onboard Display.
To configure the Symbio™ 700 controller for BACnet® MS/TP Protocol:

1. Set theProtocol selection to BACnet® MS/TP.
2. Verify theBaud Rate (default is 76,800 bps). All BACnet® MS/TP devices on an MS/TP link must communicate at the same baud rate.
3. Verify theCurrent Device ID. To change the device ID, tap Use Software Device ID and enter the desired device ID (See Figure 9).
   Note: The valid Device ID range using a software Device ID is 1 – 4194302 as defined by the BACnet standard.

Air-Fi® Wireless

Air-Fi Wireless – Conforms to ANSI/ASHRAE Standard 135-2016 (BACnet®/ZigBee®1). Air-Fi Wireless provides reliable and secure, and location-flexible communication between equipment controls, sensors, and service tools to the system controller.
Air-Fi networks will be setup by a Trane technician. Integration to a Symbio™ 700 controller setup for Air-Fi communications uses BACnet over Zigbee communications through a Tracer SC+ system controller. Contact your local Trane office for additional information if the Symbio™ 700 controller is setup for Air-Fi Wireless.

Communication Wiring

BACnet® MS/TP or Modbus RTU
The BACnet MS/TP or Modbus RTU communication wire is connected to the J17 Connector. 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 J17 Connector are used to make it easier to wire the next device in the communication daisy chain.

BACnet® IP or Modbus TCP
If using BACnet/IP or Modbus TCP using a standard Ethernet cable, connect the Ethernet cable with RJ-45 connectors to the Ethernet port.
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 MS/TP wiring.

BACnet Points List

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.

Arbitrations

Standalone Control vs Enable External/BAS Control

The Symbio™ 700 controller allows for two types of control: standalone control and external/BAS control.

Standalone Control

• The Arbitration Method Request point must be set toStandalone Control.
• In Standalone Control, the Symbio™ 700 controller will ignore all BAS input and the only way to control the equipment is through the onboard display or local inputs.
• Standalone Control should only be used in very specific situations as there is limited flexibility on control of the equipment.

Enable External/BAS Control

• The Arbitration Method Request point must be set toEnable External/BAS Control.
• In Enable External/BAS Control, the Symbio™ 700 controller will look at all available sources (wired, Air-Fi, BAS, etc) and will determine which option to use based on validity of source. In general if BAS input is not valid, the Symbio™ 700 controller will revert back to Air-Fi or wired inputs for the source.
• Enable External/BAS Control is the default setting for the equipment and is the preferred setup for most situations because of the flexibility it offers.

Space Temperature Setpoint Single Setpoint Method

The Space Temperature Single Setpoint Arbitration Method is used to determine the correct space temperature setpoint value when you have a single setpoint from various local inputs, wired or wireless, and the potential for a Building Automation System to communicate a value.
There are two methods to determine the Space Temperature Setpoint Active when using a single setpoint. The Symbio™ 700 controller will use the Arbitration Method Request point to determine the method, below is the breakdown of each step.

Standalone Control

1. The Arbitration Method Request point must be set to Standalone Control.
2. The Symbio™ 700 controller will then look at available inputs and determine which one to use.
   1. If the Symbio™ 700 controller only has a valid wired sensor input it will use it to determine the active setpoint.
   2. If the Symbio™ 700 controller only has a valid Air-Fi sensor input it will use it to determine the active setpoint.
   3. If the Symbio™ 700 controller has both a valid wired and a valid Air-Fi sensor input it will first use the Air-Fi sensor input to determine the active setpoint. If the Air-Fi sensor fails or loses communication the Symbio™ 700 controller will use the wired sensor to determine the active setpoint. If both the wired and Air-Fi sensors fail then the Symbio™ 700 controller will use the default setpoint to determine the active setpoint.
   4. The Space Temperature Setpoint BAS point is ignored during Standalone Control.
3. After determining the correct setpoint input to use the Symbio™ 700 controller will write its decision to the Space Temperature Setpoint Input Active point.
4. The Symbio™ 700 controller will then look at the Occupancy Status point and the Demand Shed Input point to determine which offsets to use.
   1. If the Occupancy Status point is Occupied or Occupied Bypass then the Symbio™ 700 will add and subtract the Occupied Offset point amount. If active, the Symbio™ 700 will also add and subtract the Demand Shed Offset Setpoint point amount.
   2. If the Occupancy Status point is Occupied Standby then the Symbio™ 700 will add and subtract the Occupied Standby Offset point amount. If active, the Symbio™ 700 will also add and subtract the Demand Shed Offset Setpoint point amount.
   3. The Symbio™ 700 controller will apply the Space Heating/Cooling Limits to the setpoints.
   4. If the Occupancy Status Point is Unoccupied then the Symbio™ 700 will use the Unoccupied Cooling Setpoint and the Unoccupied Heating Setpoints.
5. After determining the correct Occupancy Status and applying the limits the Symbio™ 700 controller will write the new heating and cooling setpoints to Space Temp Cooling Setpoint Status point and Space Temp Heating Setpoint Status point.
6. The Symbio™ 700 controller will then look at the Heat Cool Mode Status point to determine the correct active setpoint.
   1. If the Heat Cool Mode Status is Heat then the Symbio™ 700 controller will use the Space Temp Heating Setpoint Status.
   2. If the Heat Cool Mode Status is Cool then the Symbio™ 700 controller will use the Space Temp Cooling Setpoint Status.
7. After determining the correct Heat Cool Mode Status the Symbio™ 700 controller will write the correct setpoint to Space Temperature Setpoint Active.

Enable External/BAS Control

1. The Arbitration Method Request point must be set to Enable External/BAS Control.
2. The Symbio™ 700 controller will then look at the Space Temperature Setpoint BAS point to determine requested setpoint.
   1. The Space Temperature Setpoint BAS is a BACnet commandable point.
   2. If the Symbio™ 700 controller has a wired setpoint it will show as a priority 15 writing to the Space Temperature Setpoint BAS point. If the Symbio™ 700 controller has an Air-Fi setpoint it will show as a priority 14 writing to the Space Temperature Setpoint BAS point.
   3. In order for the Symbio™ 700 controller to use a communicated setpoint from a Building Automation System, a valid setpoint must be written to the Space Temperature Setpoint BAS point at a higher priority than 14. Writing at a lower priority than 14 will cause the communicated value to be ignored by the Symbio™ 700 controller.
   4. If the Air-Fi sensor fails or loses communication the Symbio™ 700 controller will use the wired sensor to determine the active setpoint. If both the wired and Air-Fi sensors fail then the Symbio™ 700 controller will use the default setpoint to determine the active setpoint.
   5. When using the Symbio™ 700 Display or Mobile Service Tool to change setpoints, these tools write to the relinquish default values and will not show up in the priority array. The relinquish default value will only be used if no other valid sensor input is available.
3. After determining the correct sensor input to use the Symbio™ 700 controller will write its decision to the Space Temperature Setpoint Input Active point.
4. The Symbio™ 700 controller will then look at the Occupancy Status point and the Demand Shed Input point to determine which offsets to use.
   1. If the Occupancy Status point is Occupied or Occupied Bypass then the Symbio™ 700 will add and subtract the Occupied Offset point amount. If active, the Symbio™ 700 will also add and subtract the Demand Shed Offset Setpoint point amount.
   2. If the Occupancy Status point is Occupied Standby then the Symbio™ 700 will add and subtract the Occupied Standby Offset point amount. If active, the Symbio™ 700 will also add and subtract the Demand Shed Offset Setpoint point amount.
   3. The Symbio™ 700 controller will apply the Space Heating/Cooling Limits to the setpoints.
   4. If the Occupancy Status Point is Unoccupied then the Symbio™ 700 will use the Unoccupied Cooling Setpoint and the Unoccupied Heating Setpoints.
5. After determining the correct Occupancy Status and applying the limits the Symbio™ 700 controller will write the new heating and cooling setpoints to Space Temp Cooling Setpoint Status point and Space Temp Heating Setpoint Status point.
6. The Symbio™ 700 controller will then look at the Heat Cool Mode Status point to determine the correct active setpoint.
   1. If the Heat Cool Mode Status is Heat then the Symbio™ 700 controller will use the Space Temp Heating Setpoint Status.
   2. If the Heat Cool Mode Status is Cool then the Symbio™ 700 controller will use the Space Temp Cooling Setpoint Status.
7. If the Heat Cool Mode Status is Heat then the Symbio™ 700 controller will use the Space Temp Heating Setpoint Status.

Space Temperature Setpoint Dual Setpoint Method

The Space Temperature Dual Setpoint Arbitration Method is used to determine the correct space temperature setpoint value when you have a two setpoints from various local inputs, wired or wireless, and the potential for a Building Automation System to communicate two values.
There are two methods to determine the Space Temperature Setpoint Active when using dual setpoints. The Symbio™ 700 controller will use the Arbitration Method Request point to determine the method, below is the breakdown of each step.

Standalone Control

1. The Arbitration Method Request point must be set to Standalone Control.
2. The Symbio™ 700 controller will then look at available inputs and determine which one to use.

   3. If the Symbio™ 700 controller has both a valid wired and a valid Air-Fi sensor input it will first use the Air-Fi sensor input to determine the active setpoints. If the Air-Fi sensor fails or loses communication the Symbio™ 700 controller will use the wired sensor to determine the active setpoint. If both the wired and Air-Fi sensors fail then the Symbio™ 700 controller will use the default setpoint to determine the active setpoint.
   4. The Occupied Cooling/Heating Setpoint BAS points are ignored during Standalone Control.
3. After determining the correct sensor input to use the Symbio™ 700 controller will write its decision to the Space Temperature Cooling/Heating Setpoint Input Active points.
4. The Symbio™ 700 controller will then look at the Occupancy Status point and the Demand Shed Input point to determine which setpoints to use.
   1. If the Occupancy Status point is Occupied or Occupied Bypass then the Symbio™ 700 will use the standard Heating/Cooling Setpoints. If active, the Symbio™ 700 will add and subtract the Demand Shed Offset Setpoint point amount.

5. After determining the correct Occupancy Status and applying the limits the Symbio™ 700 controller will write the new heating and cooling setpoints to Space Temp Cooling Setpoint Status point and Space Temp Heating Setpoint Status point.
6. The Symbio™ 700 controller will then look at the Heat Cool Mode Status point to determine the correct active setpoint.
   1. If the Heat Cool Mode Status is Heat then the Symbio™ 700 controller will use the Space Temp Heating Setpoint Status.

7. After determining the correct Heat Cool Mode Status the Symbio™ 700 controller will write the correct setpoint to Space Temperature Setpoint Active.

Enable External/BAS Control

1. The Arbitration Method Request point must be set to Enable External/BAS Control.
2. The Symbio™ 700 controller will then look at the Occupied Cooling/Heating Setpoint BAS points to determine requested setpoint.
   1. The Occupied Cooling/Heating Setpoint BAS points are BACnet® commandable point.
   2. If the Symbio™ 700 controller has a wired sensor it will show as a priority 15 writing to the Occupied Cooling/Heating Setpoint BAS points. If the Symbio™ 700 controller has an Air-Fi sensor it will show as a priority 14 writing to the Occupied Cooling/Heating Setpoint BAS points.
   3. In order for the Symbio™ 700 controller to use a communicated setpoint from a Building Automation System, a valid setpoint must be written to the Occupied Cooling/Heating Setpoint BAS points at a higher priority than 14. Writing at a lower priority than 14 will cause the communicated value to be ignored by the Symbio™ 700 controller.
   4. If the Air-Fi sensor fails or loses communication the Symbio™ 700 controller will use the wired sensor to determine the active setpoint. If both the wired and Air-Fi sensors fail then the Symbio™ 700 controller will use the default setpoint to determine the active setpoint.
   5. When using the Symbio™ 700 Display or Mobile Service Tool to change setpoints, these tools write to the relinquish default values and will not show up in the priority array. The relinquish default value will only be used if no other valid sensor input is available.
3. After determining the correct sensor input to use the Symbio™ 700 controller will write its decision to the Space Temperature Cooling/Heating Setpoint Input Active points.

Occupancy Method

Table 2. Occupancy arbitration

The Occupancy Arbitration Method is used to determine the correct Occupancy Status value when you have local inputs, wired or wireless, and the potential for a Building Automation System to communicate a value.
There are two methods to determine the Occupancy Status. The Symbio™ 700 controller will use the Arbitration Method Request point to determine the method, below is the breakdown of each step.

Standalone Control

1. The Arbitration Method Request point must be set to Standalone Control.
2. The Symbio™ 700 controller will then look at available inputs and determine which one to use.
   1. The Symbio™ 700 controller will use the wired occupancy input on the Symbio™ 700 controller to determine occupancy if no Air-Fi sensor is configured.
   2. If the Symbio™ 700 controller has both a wired and an Air-Fi sensor input it will first use the AirFi sensor input to determine the active occupancy. If the Air-Fi sensor fails or loses communication the Symbio™ 700 controller will use the wired sensor to determine the active occupancy.
   3. The Occupancy Input BAS and the Occupancy Input Arbitrator points are ignored during Standalone Control.
3. After determining the correct sensor input to use the Symbio™ 700 controller will write its decision to the Occupancy Input Active point.
4. The Symbio™ 700 controller will then look at available inputs and determine if a time override is active.
   1. The Symbio™ 700 controller will use the wired TOV input on the Symbio™ 700 controller to determine TOV if no Air-Fi sensor is configured.
   2. If the Symbio™ 700 controller has both a wired and an Air-Fi sensor input it will first use the Air-Fi sensor input to determine the TOV. If the Air-Fi sensor fails or loses communication the Symbio™ 700 controller will use the wired sensor to determine the TOV.
   3. The Timed Override Request and Timed Override Status Arbitrator points are ignored during Standalone Control.
5. After determining the TOV input and applying Occupied Bypass Time the Symbio™ 700 controller will write the TOV status to Timed Override Status Active and Timed Override Timer Is Active points.
6. The Symbio™ 700 controller will then use the three inputs shown in Table 1 along with the Unoccupied Heating/Cooling setpoints to determine the Occupancy Status.

Enable External/BAS Control

1. The Arbitration Method Request point must be set to Enable External/BAS Control.
2. The Symbio™ 700 controller will then look at available inputs and determine which one to use.
   1. In Enable External/BAS Control the Symbio™ 700 controller will use the Occupancy Input Arbitrator point to determine the active input.
   2. If the Symbio™ 700 controller has a wired sensor it will show as a priority 15 writing to the Occupancy Input Arbitrator point. If the Symbio™ 700 controller has an Air-Fi sensor it will show as a priority 14 writing to the Occupancy Input Arbitrator point.
   3. There are two ways the Symbio™ 700 controller can use a communicated occupancy command from a Building Automation System.
      1. To write a binary occupancy command to the Symbio™ 700 controller the Building Automation System must write a valid command to the Occupancy Input BAS point. The Occupancy Input BAS has a heartbeat and must be written to once every 15 minutes or the point will fail, and the value will be ignored. Once the Occupancy Input BAS point has been written to the value will show up on the Occupancy Input Arbitrator point as a priority 12.
      2. To write a multistate occupancy command to the Symbio™ 700 controller the Building Automation System must write a valid command to the Occupancy Request point. The Occupancy Request point is a commandable point and does not have a heartbeat.
      3. The Building Automation System only needs to write to either the binary point OR the multistate point, not both.
3. After determining the correct input to use the Symbio™ 700 controller will write its decision to the Occupancy Input Active point.
4. The Symbio™ 700 controller will then look at available inputs and determine if a time override is active.
   1. In Enable External/BAS Control the Symbio™ 700 controller will use the Timed Override Status Arbitrator point to determine the active input.
   2. If the Symbio™ 700 controller has a wired sensor it will show as a priority 15 writing to the Timed Override Status Arbitrator point. If the Symbio™ 700 controller has an Air-Fi sensor it will show as a priority 14 writing to the Timed Override Status Arbitrator point.
   3. In order to use communicated value from a Building Automation System, a valid value must be written to the Time Override Request point. Once the Time Override Request point has been written to the value will show up on the Timed Override Status Arbitrator point as a priority 12.
5. After determining the TOV input and applying Occupied Bypass Time the Symbio™ 700 controller will write the TOV status to Timed Override Status Active and Timed Override Timer Is Active points.
6. The Symbio™ 700 controller will then use the three inputs shown in Table 1 along with the Unoccupied Heating/Cooling setpoints to determine the Occupancy Status.

Sensor Complex Method

The Sensor Complex Arbitration Method is used to determine the correct sensor value when you have local inputs, wired or wireless, and the potential for a Building Automation System to communicate a value. This arbitration method uses a heartbeat on the BAS point to help determine the validity of the communicated value.

   1. In Enable External/BAS Control the Symbio™ 700 controller will use the sensor Arbitrator point to determine the active input.
   2. If the Symbio™ 700 controller has a wired sensor it will show as a priority 15 writing to the Arbitrator point. If the Symbio™ 700 controller has an Air-Fi sensor it will show as a priority 14 writing to the Arbitrator point.
   3. In order for the Symbio™ 700 controller to use a communicated sensor value from a Building Automation System a valid sensor value must be written to the sensor BAS point. When a valid communicated sensor value is received it will show as a priority 12 writing to the Arbitrator point.
   4. The BAS point must have a valid value communicated at least once every 15 minutes or the point will fail. If the BAS point fails the priority 12 value will be removed from the Arbitrator point, and it will revert back to the next highest priority available.
3. After determining the correct input to use the Symbio™ 700 controller will write its decision to the sensor Active point.

Setpoint Simple Method

The Setpoint Simple Arbitration Method is used to determine the correct setpoint value when you only have the potential for a Building Automation System to communicate a value.

Standalone Control

1. The Arbitration Method Request point must be set to Standalone Control.
2. The Symbio™ 700 controller will then use the relinquish default set for the BAS point as the active value.
   1. The relinquish default is set from the factory and can be changed by using the display on the Symbio™ 700 controller.
3. The Symbio™ 700 will write the relinquish default value to setpoint Active point.

Enable External/BAS Control

1. The Arbitration Method Request point must be set to Enable External/BAS Control.
2. The Symbio™ 700 controller will then look at available inputs and determine which one to use.
   1. In Enable External/BAS Control the Symbio™ 700 controller will use the setpoint Arbitrator point to determine the active input.
   2. If the Symbio™ 700 controller has a wired setpoint it will show as a priority 15 writing to the Arbitrator point. If the Symbio™ 700 controller has an Air-Fi setpoint it will show as a priority 14 writing to the Arbitrator point.
   3. In order for the Symbio™ 700 controller to use a communicated setpoint value from a Building Automation System a valid setpoint value must be written to the setpoint sensor BAS point. When a valid communicated setpoint value is received it will show as a priority 12 writing to the Arbitrator point.
   4. The BAS point must have a valid value communicated at least once every 15 minutes or the point will fail. If the BAS point fails the priority 12 value will be removed from the Arbitrator point, and it will revert back to the next highest priority available.
3. After determining the correct input to use the Symbio™ 700 controller will write its decision to the setpoint Active point.

Setpoint/Mode Complex Method

The Setpoint/Mode Complex Arbitration Method is used to determine the correct setpoint value when you have local inputs, wired or wireless, and the potential for a Building Automation System to communicate a value. Demand Limit

Standalone Control

1. The Arbitration Method Request point must be set to Standalone Control.
2. The Symbio™ 700 controller will then look at available inputs and determine which one to use.
   1. The Symbio™ 700 controller will use the wired input on the Symbio™ 700 controller to determine the active value if no Air-Fi setpoint is configured.
   2. If the Symbio™ 700 controller has both a wired and an Air-Fi setpoint input it will first use the AirFi setpoint input to determine the active value. If the Air-Fi setpoint fails or loses communication the Symbio™ 700 controller will use the wired setpoint to determine the active value.
   3. The setpoint BAS is ignored during Standalone Control.
3. After determining the correct setpoint input to use the Symbio™ 700 controller will write its decision to the setpoint Active point.

Enable External/BAS Control

1. The Arbitration Method Request point must be set to Enable External/BAS Control.
2. The Symbio™ 700 controller will then look at available inputs and determine which one to use.
   1. In Enable External/BAS Control the Symbio™ 700 controller will use the setpoint BAS point to determine the active input.
   2. If the Symbio™ 700 controller has a wired setpoint it will show as a priority 15 writing to the Arbitrator point. If the Symbio™ 700 controller has an Air-Fi setpoint it will show as a priority 14 writing to the Arbitrator point.
   3. In order for the Symbio™ 700 controller to use a communicated setpoint value from a Building Automation System a valid setpoint value must be written to the setpoint BAS point at a priority higher than 14.
3. After determining the correct input to use the Symbio™ 700 controller will write its decision to the setpoint Active point.
