TSI PresSura RPC30 Room Pressure Controller BACnet points list
Updated 6 November 2026
The RPC30 measures room pressure and drives the exhaust and supply air valves (and optionally reheat) to keep a room positive, negative or at no isolation. Over BACnet MS/TP it exposes room pressure, flows, temperatures, control outputs, the pressure and temperature setpoints, flow limits, alarm limits, the room mode and a Status Index alarm code.
This page lists 81 BACnet objects for the TSI PresSura RPC30 Room Pressure Controller — 51 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from TSI’s own free documentation, linked below.

BMS integration notes: TSI PresSura RPC30 Room Pressure Controller
Write the room mode (MV 11) and, if needed, the negative or positive pressure setpoint (AV 12/13). Read room pressure, flows, the control outputs and the Status Index (MV 16) for alarms. Occupancy is a wired input (BI 4) that switches between the occupied and unoccupied flow and temperature setpoints.
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.

| MV 11 | Room 1 Mode | 1 = positive, 2 = negative, 3 = no isolation | Write |
| AV 12 | Room 1 Neg Setpoint | Negative-mode pressure setpoint, in. W.C. | Write |
| AV 13 | Room 1 Pos Setpoint | Positive-mode pressure setpoint, in. W.C. | Write |
| AI 1 | Room1 Pressure | Room differential pressure | Read |

| AI 6 | Exhaust Flow Rate | Exhaust airflow | Read |
| AI 5 | Room Temperature | Room temperature | Read |
| AI 14 | Exhaust Control Output | Exhaust valve output, % open | Read |
| BI 4 | Room 1 Occupancy | 0 = occupied, 1 = unoccupied | Read |
| MV 16 | Status Index | Active alarm code; 1 = normal | Read |
Sensors & values from the BMS
Relative humidity can come from the BMS: set BV 10 to Enable and write AV 56.
Network setup
- Set Comm Type to BACnet in the Interface menu (Modbus is the default); Address (1-127) is the MS/TP MAC and MAC ID is the BACnet device ID.
- BACnet MS/TP baud: 9600, 19200, 38400, 76800 or AutoBaud.
Watch out for
- Engineering units follow Units Value (MV 18): 1 = in. W.C./cfm/°F (default), 2 = Pa/lps/°C, 3 = Pa/CMH/°C.
- In No Isolation mode the controller holds the No Isolation setpoint (AV 14) by position, flow or pressure, per MV 13.
- Setpoints, flow limits and alarm limits are stored settings; do not write them cyclically.

Integration notes
- From the RPC30 BACnet MS/TP Object Set appendix (manual pages 102-106).
- Access follows the Writable Value column; AI 10 and AI 11 have a writable object name (the room label) and are shown here as read-only values.
- Units shown are the English set; the table lists Pa, l/s, CMH and °C alternatives, chosen with Units Value (MV 18).
- AV 12 and AV 13 (pressure setpoints) and AV 44/45 have no units printed in the table.
- The Revision J link for this manual serves the same file (Revision L).
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 PresSura RPC30 Room Pressure Controller and exports what it actually has to Excel — free.

Questions about the TSI PresSura RPC30 Room Pressure Controller
How many BACnet points does the TSI PresSura RPC30 Room Pressure Controller have?
This list has 81 BACnet objects: 13 analog inputs, 42 analog values, 4 binary inputs, 5 binary values, 17 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which TSI PresSura RPC30 Room Pressure Controller BACnet points are writable?
51 of the 81 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 TSI PresSura RPC30 Room Pressure Controller BACnet documentation?
The source is PresSura Room Pressure Controller Model RPC30 Operation and Service Manual (P/N 6006643), revision Revision L, February 2023, published free by TSI at https://tsi.com/getmedia/a6941791-3bdc-4d01-abe2-b7d1fd9eae4e/RPC30_PresSura_Controller_6006643L-web?ext=.pdf.
What are the minimum BACnet points to integrate the TSI PresSura RPC30 Room Pressure Controller?
Start with MV 11 Room 1 Mode (1 = positive, 2 = negative, 3 = no isolation); AV 12 Room 1 Neg Setpoint (Negative-mode pressure setpoint, in. W.C); AV 13 Room 1 Pos Setpoint (Positive-mode pressure setpoint, in. W.C); AI 1 Room1 Pressure (Room differential pressure); AI 2 Supply Flow Rate (Supply airflow); AI 6 Exhaust Flow Rate (Exhaust airflow); AI 5 Room Temperature (Room temperature); AI 14 Exhaust Control Output (Exhaust valve output, % open); BI 4 Room 1 Occupancy (0 = occupied, 1 = unoccupied); MV 16 Status Index (Active alarm code; 1 = normal).
Can the BMS supply sensor values to the TSI PresSura RPC30 Room Pressure Controller?
Relative humidity can come from the BMS: set BV 10 to Enable and write AV 56.
How do I check these points on the real PresSura RPC30 Room Pressure Controller?
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.
