Trane BCI2-I (IntelliPak) BACnet points list

Updated 4 November 2026

Short answer

The BCI2-I is a non-programmable BACnet MS/TP card for IntelliPak rooftops and Commercial Self-Contained units. It scans the unit at first power-up and creates only the objects that match the installed options, so the full table is a superset. The BAS writes AO/BO/MO output objects (commands, setpoints, BAS sensor values) and reads AI/BI/MI status and diagnostics. This is the older IntelliPak interface, not the Symbio 800 IntelliPak controller.

This page lists 331 BACnet objects for the Trane BCI2-I (IntelliPak) — 54 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 BCI2-I (IntelliPak)

Integration in brief

Set Unit Control to BAS/NETWORK at the unit's Human Interface, then set BO 1 System Control Command to Active (BAS Control). Put each output object the BMS will drive in service (Out_Of_Service = FALSE). Schedule with MO 7 Occupancy Request, set the mode with MO 8 and the space setpoint with AO 2 (or the discharge air setpoints on VAV units). Keep rewriting BAS sensor values.

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.

ObjectNameWhyAccess
BO 1System Control CommandActive = BAS control; Inactive = standalone, monitor onlyCommand
MO 7Occupancy RequestOccupancy command (1 = Occupied, 2 = Unoccupied)Command
MO 8Heat Cool Mode Request BASHeat/cool mode command (1 = Auto)Command

BI 165Alarm Relay Output StatusUnit alarm relay; Active = energizedRead

Enable & remote start

At the unit Human Interface, BAS Communication Module must read Installed and Setup > Unit Control must be BAS/NETWORK. Then BO 1 System Control Command must be Active (BAS Control); while Inactive the unit runs on local sensors and setpoints and ignores BAS values. Output objects ship with Out_Of_Service = TRUE, so the unit uses its local value until the BMS sets Out_Of_Service to FALSE on each output it will write.

Heartbeat & communication loss

BAS-supplied sensor objects with a 900 s refresh rate (AO 10-15, AO 17, AO 18, AO 25) must be rewritten within that time. If not, the BCI2-I puts the object in fault and the unit reverts to its own sensor. At power-up these objects stay in fault until the first write. Setpoints and commands have no refresh limit (AO 22 is printed with a 5 s refresh rate).

Sensors & values from the BMS

Write BMS sensor values to the '... BAS' AOs (AO 11 Space Temperature BAS, AO 12 Discharge Air Temperature BAS, AO 13 Duct Static Pressure BAS, AO 14 Outdoor Air Temperature BAS, AO 15 Outdoor Air Humidity BAS, AO 17 Outdoor Air Flow BAS, AO 18 Space CO2 Concentration BAS, AO 25 Space Humidity BAS, AO 10 Space Static Pressure BAS) with the object in service, and keep refreshing them. The matching '... Active' AIs 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 BCI2-I (IntelliPak) 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 BCI2-I (IntelliPak)

How many BACnet points does the Trane BCI2-I (IntelliPak) have?

This list has 331 BACnet objects: 82 analog inputs, 33 analog outputs, 3 analog values, 161 binary inputs, 11 binary outputs, 34 multi-state inputs, 7 multi-state outputs. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Trane BCI2-I (IntelliPak) BACnet points are writable?

54 of the 331 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 BCI2-I (IntelliPak) BACnet documentation?

The source is Integration Guide: BACnet Communication Interface (BCI2-I) for IntelliPak and Commercial Self-Contained (BAS-SVP054B-EN), revision September 2023, published free by Trane at https://elibrary.tranetechnologies.com/public/commercial-hvac/Literature/Integration/BAS-SVP054B-EN_09222023.pdf.

What are the minimum BACnet points to integrate the Trane BCI2-I (IntelliPak)?

Start with BO 1 System Control Command (Active = BAS control; Inactive = standalone, monitor only); MO 7 Occupancy Request (Occupancy command (1 = Occupied, 2 = Unoccupied)); MO 8 Heat Cool Mode Request BAS (Heat/cool mode command (1 = Auto)); AO 2 Space Temperature Setpoint BAS (Space setpoint; occupied/standby offsets apply to it); AO 6 Discharge Air Cooling Setpoint BAS (Supply air cooling setpoint on VAV units); BI 1 System Control Status (Confirms the unit is under BAS control); MI 20 Occupancy Status (Confirms the occupancy the unit is running in); MI 41 Supply Fan Status (Supply fan on/off (2 = On)); AI 15 Space Temperature Active (Space temperature the unit is controlling to); BI 165 Alarm Relay Output Status (Unit alarm relay; Active = energized).

How do I enable BMS control of the Trane BCI2-I (IntelliPak)?

At the unit Human Interface, BAS Communication Module must read Installed and Setup > Unit Control must be BAS/NETWORK. Then BO 1 System Control Command must be Active (BAS Control); while Inactive the unit runs on local sensors and setpoints and ignores BAS values. Output objects ship with Out_Of_Service = TRUE, so the unit uses its local value until the BMS sets Out_Of_Service to FALSE on each output it will write.

Does the Trane BCI2-I (IntelliPak) need a BACnet heartbeat or have a communication timeout?

BAS-supplied sensor objects with a 900 s refresh rate (AO 10-15, AO 17, AO 18, AO 25) must be rewritten within that time. If not, the BCI2-I puts the object in fault and the unit reverts to its own sensor. At power-up these objects stay in fault until the first write. Setpoints and commands have no refresh limit (AO 22 is printed with a 5 s refresh rate).

Can the BMS supply sensor values to the Trane BCI2-I (IntelliPak)?

Write BMS sensor values to the '... BAS' AOs (AO 11 Space Temperature BAS, AO 12 Discharge Air Temperature BAS, AO 13 Duct Static Pressure BAS, AO 14 Outdoor Air Temperature BAS, AO 15 Outdoor Air Humidity BAS, AO 17 Outdoor Air Flow BAS, AO 18 Space CO2 Concentration BAS, AO 25 Space Humidity BAS, AO 10 Space Static Pressure BAS) with the object in service, and keep refreshing them. The matching '... Active' AIs show the value in use.

How do I check these points on the real BCI2-I (IntelliPak)?

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.
