Trane Tracer UC600 Packaged Outdoor Air Unit BACnet points list

Updated 4 November 2026

Short answer

The Tracer UC600 is a programmable B-AAC controller; on packaged outdoor air units it runs a Trane program exposing about 175 objects with short instances (AI 1, AV 20, BV 16...). The BMS commands occupancy with MV 1 and writes '... BAS' values for sensors and setpoints, which ship Out of Service and must be put In Service first. Which objects are used depends on the unit type and options (space, discharge or VAV control, heat pump, gas heat, ERV).

This page lists 175 BACnet objects for the Trane Tracer UC600 Packaged Outdoor Air Unit — 58 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 Tracer UC600 Packaged Outdoor Air Unit

Integration in brief

Command occupancy with MV 1 Occupancy Request and send setpoints (AV 25 space setpoint, AV 30/AV 32 discharge setpoints, AV 67 on multizone VAV). If the BMS supplies sensor values, put the '... BAS' objects In Service and keep refreshing them. Read MV 2, BI 1, AV 5 and the diagnostic BVs; clear latching lockouts with BV 16 Alarm Reset.

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.

Enable & remote start

No enable point is described. The BAS controls the unit by writing values and putting points In or Out of Service. MV 1 Occupancy Request sets occupancy.

Heartbeat & communication loss

The guide says the BAS must routinely refresh BAS-supplied sensor values to protect against a communication loss, but gives no timeout value.

Sensors & values from the BMS

Space Temperature BAS (AV 20), Space RH BAS (AV 8), Outdoor Air Temperature BAS (AV 75), Outdoor Air Humidity BAS (AV 81) and Discharge Air Temperature BAS (AV 4) are Out of Service from the factory; put them In Service to use them and keep rewriting them. The matching '... Active' AVs show the value in use.

Integration notes

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 Tracer UC600 Packaged Outdoor Air Unit and exports what it actually has to Excel — free.

Questions about the Trane Tracer UC600 Packaged Outdoor Air Unit

How many BACnet points does the Trane Tracer UC600 Packaged Outdoor Air Unit have?

This list has 175 BACnet objects: 23 analog inputs, 9 analog outputs, 66 analog values, 9 binary inputs, 17 binary outputs, 41 binary values, 10 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Trane Tracer UC600 Packaged Outdoor Air Unit BACnet points are writable?

58 of the 175 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 Tracer UC600 Packaged Outdoor Air Unit BACnet documentation?

The source is Integration Guide: Tracer UC600 Programmable Controller, Packaged Outdoor Air Unit (BAS-SVP18E-EN), revision July 2022, published free by Trane at https://elibrary.tranetechnologies.com/public/commercial-hvac/Literature/Integration/BAS-SVP18E-EN_07012022.pdf.

What are the minimum BACnet points to integrate the Trane Tracer UC600 Packaged Outdoor Air Unit?

Start with MV 1 Occupancy Request (Occupancy command (1 = Occupied, 2 = Unoccupied, 5 = Auto)); AV 25 Space Temperature Setpoint BAS (Space setpoint (space control / single zone VAV)); AV 30 Discharge Air Cooling Setpoint (Discharge air cooling setpoint (discharge control)); AV 32 Discharge Air Heating Setpoint (Discharge air heating setpoint (discharge control)); BV 16 Alarm Reset (1 = reset diagnostics and lockouts; return to 0 after); MV 2 Occupancy Status (Confirms the occupancy in effect); BI 1 Supply Fan Status (Supply fan proof (0 = On, 1 = Off)); AV 5 Discharge Air Temperature Active (Discharge air temperature in use); BV 17 System LOCKOUT (Unit locked out; needs Alarm Reset); BV 1 Diagnostic: Supply Fan Failure (Supply fan failure (latching)).

How do I enable BMS control of the Trane Tracer UC600 Packaged Outdoor Air Unit?

No enable point is described. The BAS controls the unit by writing values and putting points In or Out of Service. MV 1 Occupancy Request sets occupancy.

Does the Trane Tracer UC600 Packaged Outdoor Air Unit need a BACnet heartbeat or have a communication timeout?

The guide says the BAS must routinely refresh BAS-supplied sensor values to protect against a communication loss, but gives no timeout value.

Can the BMS supply sensor values to the Trane Tracer UC600 Packaged Outdoor Air Unit?

Space Temperature BAS (AV 20), Space RH BAS (AV 8), Outdoor Air Temperature BAS (AV 75), Outdoor Air Humidity BAS (AV 81) and Discharge Air Temperature BAS (AV 4) are Out of Service from the factory; put them In Service to use them and keep rewriting them. The matching '... Active' AVs show the value in use.

How do I check these points on the real Tracer UC600 Packaged Outdoor Air Unit?

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.
