Trane Symbio 500 Modular Self-Contained (SCWM) BACnet points list
Updated 28 October 2026
Short answer
The Symbio 500 on modular self-contained units exposes about 510 objects, including hardware AI/AO/BI/BO points. Most writable setpoints are AVs and BVs with relinquish defaults and, for some, heartbeat timeouts. Points depend on the unit's compressor count, economizer and heat options.
This page lists 511 BACnet objects for the Trane Symbio 500 Modular Self-Contained (SCWM) — 111 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 500 Modular Self-Contained (SCWM)
Integration in brief
In the Symbio UI (USB, http://198.80.18.1), use BAS Control Selection to set each sensor and setpoint to BAS or Local. Then schedule with MV 1 Occupancy Request, write the setpoint BAS AVs and use BV 329 Front Panel Auto Stop to run or stop the unit. MV 60/61/62 show whether each value is coming from the BAS, local or default.
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 |
|---|---|---|---|
| MV 1 | Occupancy Request | Occupancy command from the BMS schedule | Write |
| BV 329 | Front Panel Auto Stop | Auto/stop of the unit (relinquish default is Stop) | Write |
| MV 3 | Heat Cool Mode Request | Mode command from the BMS | Write |
| AV 7 | Space Temperature Setpoint BAS | Space setpoint from the BMS | Write |
| AV 24 | Discharge Air Cooling Setpoint BAS | Supply air cooling setpoint from the BMS | Write |
| AV 91 | Duct Static Pressure Setpoint BAS | Duct static setpoint from the BMS | Write |
| MV 2 | Occupancy Status | Confirms the occupancy in effect | Read |
| BV 360 | Supply Fan Calculated Status | Any supply fan running | Read |
| AI 11 | Discharge Air Temperature | Supply air temperature | Read |
| MV 83 | MSC Unit Status | Overall unit status: normal, off, warning, alarm, stops | Read |
Enable & remote start
BAS vs Local is chosen per sensor and setpoint with the BAS Control Selection tool in the Symbio UI. BV 329 Front Panel Auto Stop (Auto/Stop, relinquish default Stop) and BI 10 External Auto Stop Input Status cover unit start/stop. The documents don't spell out how those two interact.
Heartbeat & communication loss
Only AV 77 Space Temperature BAS lists a heartbeat (900 s) in the points list; the other BAS points list 0. The documents don't describe what happens on expiry. BV 11 'Diagnostic: Space Temperature Source Failure' is the related alarm flag.
Sensors & values from the BMS
Set the sensor to BAS in BAS Control Selection, then write AV 77 Space Temperature BAS, AV 75 Outdoor Air Temperature BAS, AV 79 Space Humidity BAS or AV 81 Outdoor Air Humidity BAS. MV 62 Space Temperature Source Status shows BAS/Local/Default, and the 'Source Failure' BVs (BV 11-14, BV 42) flag a lost source.
Network setup
- The three rotary switches set the MS/TP MAC and, by default, the Device ID. Use 001-120 on MS/TP (000 is reserved for Tracer SC+); IP or Zigbee units allow 001-999.
- Set the rotary address before power-up; a change takes effect after a power cycle.
- For a Device ID above 127, enable 'Use Software Device ID' in Symbio UI or Tracer TU (TU needs a power cycle); this disables the rotary method.
- Saving protocol, IP or system-unit settings in Symbio UI restarts the controller, so the unit stops briefly.
- System units (IP/SI) set in Symbio UI change the units sent over BACnet.
Watch out for
- Only the points for the unit's options are present (compressor count, economizer, heat type).
- AO/BO hardware outputs are read-only status in this list; command the unit through the BAS value objects.
- Tracer SC+ sets the software Device ID automatically during discovery; third-party systems must set it themselves.

Integration notes
- Only the points that apply to the unit's factory configuration show up; the doc lists every possible point.
- Name suffixes carry meaning: Status/Local/Active/Input are read-only, BAS/Command/Request/Setpoint value objects are the ones a BAS writes, and Arbitrator objects show which source is winning.
- The Symbio 500 integration guide (BAS-SVP087) centers on BACnet MS/TP (rotary address 001-120) and also mentions BACnet/IP connections.
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. Easy BACnet scans a network for BACnet IP devices from an Android phone, reads every object on the Symbio 500 Modular Self-Contained (SCWM) 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 500 Modular Self-Contained (SCWM)
How many BACnet points does the Trane Symbio 500 Modular Self-Contained (SCWM) have?
This list has 511 BACnet objects: 32 analog inputs, 17 analog outputs, 189 analog values, 30 binary inputs, 18 binary outputs, 178 binary values, 47 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Trane Symbio 500 Modular Self-Contained (SCWM) BACnet points are writable?
111 of the 511 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.
Where is the official Trane Symbio 500 Modular Self-Contained (SCWM) BACnet documentation?
The source is Symbio 500 Integration Point List BACnet - Modular Self-Contained (SCWM) (BAS-PTS037A-EN), revision 07/31/2025, published free by Trane at https://elibrary.tranetechnologies.com/public/commercial-hvac/Literature/Points%20List/BAS-PTS037A-EN_07312025.pdf.
What are the minimum BACnet points to integrate the Trane Symbio 500 Modular Self-Contained (SCWM)?
Start with MV 1 Occupancy Request (Occupancy command from the BMS schedule); BV 329 Front Panel Auto Stop (Auto/stop of the unit (relinquish default is Stop)); MV 3 Heat Cool Mode Request (Mode command from the BMS); AV 7 Space Temperature Setpoint BAS (Space setpoint from the BMS); AV 24 Discharge Air Cooling Setpoint BAS (Supply air cooling setpoint from the BMS); AV 91 Duct Static Pressure Setpoint BAS (Duct static setpoint from the BMS); MV 2 Occupancy Status (Confirms the occupancy in effect); BV 360 Supply Fan Calculated Status (Any supply fan running); AI 11 Discharge Air Temperature (Supply air temperature); MV 83 MSC Unit Status (Overall unit status: normal, off, warning, alarm, stops).
How do I enable BMS control of the Trane Symbio 500 Modular Self-Contained (SCWM)?
BAS vs Local is chosen per sensor and setpoint with the BAS Control Selection tool in the Symbio UI. BV 329 Front Panel Auto Stop (Auto/Stop, relinquish default Stop) and BI 10 External Auto Stop Input Status cover unit start/stop. The documents don't spell out how those two interact.
Does the Trane Symbio 500 Modular Self-Contained (SCWM) need a BACnet heartbeat or have a communication timeout?
Only AV 77 Space Temperature BAS lists a heartbeat (900 s) in the points list; the other BAS points list 0. The documents don't describe what happens on expiry. BV 11 'Diagnostic: Space Temperature Source Failure' is the related alarm flag.
Can the BMS supply sensor values to the Trane Symbio 500 Modular Self-Contained (SCWM)?
Set the sensor to BAS in BAS Control Selection, then write AV 77 Space Temperature BAS, AV 75 Outdoor Air Temperature BAS, AV 79 Space Humidity BAS or AV 81 Outdoor Air Humidity BAS. MV 62 Space Temperature Source Status shows BAS/Local/Default, and the 'Source Failure' BVs (BV 11-14, BV 42) flag a lost source.
How do I check these points on the real Symbio 500 Modular Self-Contained (SCWM)?
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.
