Paragon Controls MicroTransII flow / pressure transmitter-controller (BACnet MS/TP) BACnet points list
Updated 12 November 2026
The MicroTransII is a flow or pressure transmitter with a built-in loop controller, on BACnet MS/TP through an add-on communication board. Besides the measurements and alarm settings it exposes the controller setpoints, tuning, output and the system start / hold input status.
This page lists 31 BACnet objects for the Paragon Controls MicroTransII flow / pressure transmitter-controller (BACnet MS/TP) — 20 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Paragon Controls’s own free documentation, linked below.

BMS integration notes: Paragon Controls MicroTransII flow / pressure transmitter-controller (BACnet MS/TP)
Write the controller setpoint (AV 8 for flow, AV 7 for pressure) and read the measurement, the controller output AO 1, the system start status and the alarm status multistates. Set MSV 8 to Network to feed temperature from the BMS through AI 3.
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 |
|---|---|---|---|
| AV 8 | Flow Controller Setpoint | Controller setpoint in flow mode | Write |
| AV 7 | Pressure Controller Setpoint | Controller setpoint in pressure mode | Write |
| AI 3 | Temperature | Temperature; BMS writes it when MSV 8 = Network | Write |
| BI 1 | Sys Start In Status | System start input, 1 = run | Read |
| AI 2 | Flow | Flow or velocity reading | Read |
| AI 1 | Pressure | Pressure reading | Read |
| AO 1 | Controller Output | Controller output | Read |
| MV 2 | Hi Alarm Status | High alarm, 2 = alarm | Read |
| MV 4 | Lo Alarm Status | Low alarm, 2 = alarm | Read |
Enable & remote start
Run/stop comes from the hard-wired system start input; BI 1 only reports it.
Sensors & values from the BMS
Temperature can come from the BMS: set MSV 8 Temperature Source to 3 (Network) and write AI 3.
Network setup
- MS/TP MAC address 2-127, unique on each trunk; set at the device (see the device O&M).
- Baud 9600, 19200, 38400 or 76800.
- Device instance 1,002 to 4,194,302.
- Turn the BACnet terminator switch ON only on the two end devices of the trunk.
Watch out for
- MSV 6 state meanings change with the process type (flow, velocity or pressure).
- The controller output AO 1 is read-only.

Integration notes
- The manual gives each object as '<object type> <number> - <label>'; the label is used here as the object name.
- Units of the process values follow the engineering-units multistate; they are not printed per object.
- MSV 6 state text depends on MSV 9 / MSV 10 (flow, velocity or pressure); all three sets are given in the states field.
- AV 7 and AV 11 labels are cut off in the printed table; the full names were read from the PDF text layer.
- Device instance range 1,002 to 4,194,302 per the manual.
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 MicroTransII flow / pressure transmitter-controller (BACnet MS/TP) and exports what it actually has to Excel — free.

Where is the official Paragon Controls MicroTransII flow / pressure transmitter-controller (BACnet MS/TP) BACnet documentation?
The source is BACnet Communication Operation & Maintenance Manual (MicroTransEQ, MicroTransII, SPM-3000, SPM-4000), revision Revision Level 003, published free by Paragon Controls at https://paragoncontrols.com/wp-content/uploads/2021/03/BACnet-IOM.pdf.
What are the minimum BACnet points to integrate the Paragon Controls MicroTransII flow / pressure transmitter-controller (BACnet MS/TP)?
Start with AV 8 Flow Controller Setpoint (Controller setpoint in flow mode); AV 7 Pressure Controller Setpoint (Controller setpoint in pressure mode); AI 3 Temperature (Temperature; BMS writes it when MSV 8 = Network); BI 1 Sys Start In Status (System start input, 1 = run); AI 2 Flow (Flow or velocity reading); AI 1 Pressure (Pressure reading); AO 1 Controller Output (Controller output); MV 2 Hi Alarm Status (High alarm, 2 = alarm); MV 4 Lo Alarm Status (Low alarm, 2 = alarm).
How do I enable BMS control of the Paragon Controls MicroTransII flow / pressure transmitter-controller (BACnet MS/TP)?
Run/stop comes from the hard-wired system start input; BI 1 only reports it.
Can the BMS supply sensor values to the Paragon Controls MicroTransII flow / pressure transmitter-controller (BACnet MS/TP)?
Temperature can come from the BMS: set MSV 8 Temperature Source to 3 (Network) and write AI 3.
How do I check these points on the real MicroTransII flow / pressure transmitter-controller (BACnet MS/TP)?
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.
