Trane Symbio 800 RTHD (UC800) BACnet points list
Updated 28 October 2026
A Symbio 800 list of about 245 objects for RTHD chillers marked UC800, with small instance numbers. About 170 are diagnostic binary inputs (BI 500 and up); the rest cover water temperatures and flows, refrigerant pressures, starter and drive data and heat recovery. The BAS writes setpoints (AV), base loading, heat recovery and reset (BV) and auto/stop and mode (MV).
This page lists 244 BACnet objects for the Trane Symbio 800 RTHD (UC800) — 10 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 RTHD (UC800)
Put the chiller on the network (BACnet MS/TP or IP), then write the auto/stop command, chilled water setpoint, current 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. The alarm-present flag gives a single summary alarm.
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 |
|---|---|---|---|

Enable & remote start
MV 1 BAS Chiller Auto Stop Command (1 = Stop, 2 = Auto; relinquish default Auto) is the BMS auto/stop. BI 1 Run Enable shows stop/auto. The document doesn't say how to hand setpoint control to the BAS; BI 2 Local Setpoint Control shows when the chiller is using local setpoints instead of BAS setpoints.
Heartbeat & communication loss
No timeout or heartbeat is described. MI 3 BAS Communication Status (established/lost/never established/starting) and the diagnostic flags BI 510 BAS Communication Loss, BI 511 and BI 512 report the BAS link; the document doesn't say what the chiller does on loss.
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.
- This list has no read/write column; writability of the command and setpoint objects is inferred from their object type and relinquish defaults.
- Relinquish defaults: AV 1 44 °F (6.7 °C), AV 2 100 % RLA, AV 3 120 °F (48.9 °C), AV 4 50 %, MV 1 Auto, MV 2 Cool. Releasing MV 1 leaves the chiller in Auto.
- MI 2 is named Chiller Mode Command but is a read-only input; write MV 2 BAS Chiller Mode Command.
- Diagnostic BIs are one object per alarm condition and only exist for the options fitted.

Integration notes
- Only the points that apply to the unit's factory configuration show up; the doc lists every possible point.
- The tables have no read/write column: AI/BI/MI are read-only, and the AV/BV/MV objects (listed with a relinquish default and valid range) are the BAS setpoints and commands, marked writable here.
- The analog tables give only the data type (Real) instead of engineering units, so units are blank here.
- BI 500 and up are diagnostic flags, one per alarm condition; the document lists their names only, with no state text.
- 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.
- Trane titles this list 'RTHD (UC800)' and does not explain the suffix in the document. Its objects use short instance numbers (AI 1, BI 4...) instead of the 5-digit numbering in the standard Symbio 800 RTHD list (BAS-PTS015), so check which list matches the controller on site.
- The same document also has a Modbus register map; 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 RTHD (UC800) 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 RTHD (UC800)
How many BACnet points does the Trane Symbio 800 RTHD (UC800) have?
This list has 244 BACnet objects: 45 analog inputs, 5 analog values, 182 binary inputs, 3 binary values, 7 multi-state inputs, 2 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Trane Symbio 800 RTHD (UC800) BACnet points are writable?
10 of the 244 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 RTHD (UC800) BACnet documentation?
The source is Symbio 800 Integration Points List BACnet - RTHD (UC800) (BAS-PTS034A-EN), revision 12/6/2024, published free by Trane at https://elibrary.tranetechnologies.com/public/commercial-hvac/Literature/Points%20List/BAS-PTS034A-EN_12062024.pdf.
What are the minimum BACnet points to integrate the Trane Symbio 800 RTHD (UC800)?
Start with MV 1 BAS Chiller Auto Stop Command (BMS auto/stop command (1 = Stop, 2 = Auto)); MV 2 BAS Chiller Mode Command (Cool/heat/ice mode command); AV 1 BAS Chilled Water Setpoint (Chilled water setpoint from the BMS); AV 2 BAS Current Limit Setpoint (Current limit from the BMS, % RLA); BI 4 Chiller Running (Chiller on/off status); BI 2 Local Setpoint Control (Shows if local setpoints override BAS setpoints); AI 13 Evaporator Leaving Water Temperature (Leaving chilled water temperature); AI 4 Actual Running Capacity (Actual running capacity in percent); BI 12 Alarm Present (Any active alarm on the chiller).
How do I enable BMS control of the Trane Symbio 800 RTHD (UC800)?
MV 1 BAS Chiller Auto Stop Command (1 = Stop, 2 = Auto; relinquish default Auto) is the BMS auto/stop. BI 1 Run Enable shows stop/auto. The document doesn't say how to hand setpoint control to the BAS; BI 2 Local Setpoint Control shows when the chiller is using local setpoints instead of BAS setpoints.
Does the Trane Symbio 800 RTHD (UC800) need a BACnet heartbeat or have a communication timeout?
No timeout or heartbeat is described. MI 3 BAS Communication Status (established/lost/never established/starting) and the diagnostic flags BI 510 BAS Communication Loss, BI 511 and BI 512 report the BAS link; the document doesn't say what the chiller does on loss.
How do I check these points on the real Symbio 800 RTHD (UC800)?
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.
