Trane Symbio 800 Ascend ACS / ACX BACnet points list

Updated 28 October 2026

Short answer

Ascend ACS/ACX chillers expose about 400 BACnet objects through the Symbio 800. Status values are AI/BI/MI, and the BAS writes a small set of AV/BV/MV objects for chilled and hot water setpoints, demand limit, mode, circuit lockouts and auto/stop. Most binary inputs are individual diagnostic flags.

This page lists 397 BACnet objects for the Trane Symbio 800 Ascend ACS / ACX — 16 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Trane’s own free documentation, linked below.

BMS integration notes: Trane Symbio 800 Ascend ACS / ACX

Integration in brief

Put the chiller on the network (BACnet MS/TP or IP), then write the auto/stop command, chilled water setpoint, demand limit and mode. Read back running state, leaving water temperature and capacity. Check the local-setpoint flag to confirm the BAS setpoints are actually in use. Most remaining objects are read-only status and per-alarm diagnostic flags.

Minimum points to map

The short list most integrators start with — enough to run the unit from a BMS. Map more as the job needs.

Object	Name	Why	Access
BV 10107	BAS Chiller Auto Stop Command	BMS auto/stop (enable) command	Write
MV 10100	Chiller Mode Command BAS	Cool/heat/ice/free-cooling mode command	Write
AV 10100	Chilled Water Setpoint	Chilled water setpoint from the BMS	Write
AV 10101	Demand Limit Setpoint	Capacity (demand) limit from the BMS	Write
BI 10110	Chiller Running State	Chiller on/off status	Read
BI 10104	Local Setpoint Control	Shows if local setpoints override BAS setpoints	Read
AI 10101	Evaporator Leaving Water Temperature	Leaving chilled water temperature	Read
AI 10116	Actual Running Capacity	Actual running capacity in percent	Read
BI 10126	Diagnostic Present	Any active diagnostic (alarm) on the chiller	Read

Enable & remote start

BV 10107 BAS Chiller Auto Stop Command (0 = Stop, 1 = Auto) is the BMS auto/stop; with it at Auto the chiller runs when its own run conditions are met. BI 10130 External Auto Stop reports the hardwired external auto/stop input. The documents don't say how the two combine or how to hand setpoint control to the BAS; BI 10104 Local Setpoint Control shows when the chiller is using local setpoints instead of BAS setpoints, and MI 10102 Chiller Setpoint Source shows BAS, External or Front Panel.

Network setup

With no protocol specified at order, the controller ships as BACnet MS/TP at 76,800 bps with the rotary address at 000, and MS/TP is disabled at 000. Set a rotary address of 001-127 to bring it online.
The rotary address sets the MS/TP MAC and the Device ID and takes effect without a power cycle. A software Device ID (1-4194302) can be set in the web UI, Tracer SC+ or Tracer TU.
The web UI is reached only over USB at http://198.80.18.1/; the Ethernet ports do not serve it.
BACnet IP uses Ethernet port 1 (or the optional USB Wi-Fi adapter); the default UDP port is 47808. Enable BBMD only if this is the only BACnet IP device on the subnet, then fill in the BDT.
MS/TP wiring lands on the P1 link; P2 and P3 are for factory devices only, and Ethernet port 2 is only for the touch-screen display.

Watch out for

Communicated units (I-P or SI) are fixed at the factory; changing them in the field needs a Trane representative. Web UI display units do not change the BACnet values.
Points that don't apply to the unit's configuration are absent, and a technician can 'recycle' (remove) factory points from the interface, so a missing object may have been recycled.
The chiller lists have no read/write column; writability of the AV/BV/MV objects is inferred from Trane's naming convention.
Diagnostic BIs are one object per alarm condition and only exist for the options fitted.

Trane Symbio 800 Ascend ACS / ACX BACnet objects

Type: AI, AO, AV, BI, BO, BV, MI/MO/MV (multi-state) · Access: Read read-only, Write writable, Command writable with a priority array.

Note: the source document has no read/write column, so access here is inferred from the object type (inputs read-only, values writable). Confirm on the live controller before writing.

Integration notes

Only the points that apply to the unit's factory configuration show up; the doc lists every possible point.
The chiller tables have no read/write column: AI/BI/MI are read-only, and AV/BV/MV are the BAS command and setpoint objects, marked writable here per Trane's naming convention.
Units are listed as a quantity (Temperature, Pressure, Percent...); the actual engineering unit follows the controller's display-unit setting.
Binary inputs named 'Diagnostic: ...' are individual alarm flags (0/false = normal, 1/true = in alarm).
The Symbio 800 integration guide (BAS-SVP083) covers BACnet IP and BACnet MS/TP; the rotary address sets the MS/TP MAC and a default Device ID of 1-127, and a software Device ID can be set instead.
The same document also maps every object to a Modbus register; only the BACnet side is listed here.

Check it against the live device. A points list tells you what the controller can expose; the unit in front of you may differ by firmware or installed options. This list is provided as-is for reference only and may contain mistakes — confirming it before you write, map or commission anything is up to you (terms). Easy BACnet scans a network for BACnet IP devices from an Android phone, reads every object on the Symbio 800 Ascend ACS / ACX and exports what it actually has to Excel — free. New to BACnet? Start with what a BACnet points list is and what the object types mean.

Questions about the Trane Symbio 800 Ascend ACS / ACX

How many BACnet points does the Trane Symbio 800 Ascend ACS / ACX have?

This list has 397 BACnet objects: 79 analog inputs, 5 analog values, 292 binary inputs, 10 binary values, 10 multi-state inputs, 1 multi-state value. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Trane Symbio 800 Ascend ACS / ACX BACnet points are writable?

16 of the 397 objects accept a write. Points marked Command have a priority array: a write holds until it is released, so release it back to automatic when you are done. The source has no read/write column, so this is inferred from object type.

Where is the official Trane Symbio 800 Ascend ACS / ACX BACnet documentation?

The source is Symbio 800 Integration Points List BACnet - Ascend Models ACS and ACX (BAS-PTS011A-EN), revision 11/15/2024, published free by Trane at https://elibrary.tranetechnologies.com/public/commercial-hvac/Literature/Points%20List/BAS-PTS011A-EN_11152024.pdf.

What are the minimum BACnet points to integrate the Trane Symbio 800 Ascend ACS / ACX?

Start with BV 10107 BAS Chiller Auto Stop Command (BMS auto/stop (enable) command); MV 10100 Chiller Mode Command BAS (Cool/heat/ice/free-cooling mode command); AV 10100 Chilled Water Setpoint (Chilled water setpoint from the BMS); AV 10101 Demand Limit Setpoint (Capacity (demand) limit from the BMS); BI 10110 Chiller Running State (Chiller on/off status); BI 10104 Local Setpoint Control (Shows if local setpoints override BAS setpoints); AI 10101 Evaporator Leaving Water Temperature (Leaving chilled water temperature); AI 10116 Actual Running Capacity (Actual running capacity in percent); BI 10126 Diagnostic Present (Any active diagnostic (alarm) on the chiller).

How do I enable BMS control of the Trane Symbio 800 Ascend ACS / ACX?

How do I check these points on the real Symbio 800 Ascend ACS / ACX?

Scan the network with a BACnet IP browser such as Easy BACnet, open the device and compare its object list with this table. Anything missing is usually an option that isn't installed or a point that is disabled in the controller's configuration.
