Setra SRCM Room Condition Monitor (two-room) BACnet points list
Updated 12 November 2026Unofficial source
The SRCM monitors pressure, temperature, humidity and a user-defined value for a primary and a secondary room, with alarm limits per isolation mode. Its BACnet object list gives the eight readings as analog inputs, alarm limits per isolation mode and input ranges as analog values, display and alarm options as binary values, and input sources, isolation modes and banner modes as multistate values. This is a larger, two-room object list than the single-room Siemens RPM map already in the library.
This page lists 100 BACnet objects for the Setra SRCM Room Condition Monitor (two-room) — 48 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from a copy of Setra’s documentation hosted by Kele, not by Setra itself, so treat it as unofficial.

BMS integration notes: Setra SRCM Room Condition Monitor (two-room)
Read the room pressures (AI 1 / AI 2) and the alarm summary (MV 8 / MI 1) for monitoring. Set the isolation mode of each room (MV 2 / MV 13) and the alarm limits for that mode from the BMS only if the monitor is not configured locally. Temperature, humidity and user values can be written from BACnet when their input source is set to BACnet.
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 |
|---|---|---|---|
| MV 2 | Primary Room Pressure Mode | Primary isolation mode: 1 pos, 2 neg, 3 neutral | Write |
| MV 29 | Room Occupancy Status | Occupancy: 1 = Active, 2 = Standby | Write |

| AI 5 | Primary Humidity | Primary room humidity | Read |
| MI 1 | System Operation Status | Room state: normal, door, warning, alarm, ACH | Read |

| MV 8 | Pressure Alarm status | Which room is in pressure alarm | Read |
| BV 1 | Relay Status | Alarm relay state | Read |
Sensors & values from the BMS
Temperature, humidity and user-defined inputs can take their value from BACnet: set the matching input source MV (17, 19, 21, 23, 25, 27) to 3 = BACnet. The document does not say which object the BMS writes the value to.
Network setup
- The secondary room uses an external transducer on an analog channel (MV 9); set the channel ranges with AV 5 / AV 54 and AV 49-52.
Watch out for
- Alarm limits exist per isolation mode (positive, neutral, negative) for each room; write the set that matches MV 2 / MV 13.
- The analog values carry no fixed units; check BV 2-4 / BV 10 for the active unit before scaling.
- Most binary values and several multistate values are display settings; avoid cyclic writes.

Integration notes
- Object names come from the summary table (pp1-5); read/write comes from the Present_Value row of each object's property table (pp6-35). The property pages print some names differently (e.g. 'Primary Room Isolation Mode' for MV 2).
- Twenty Character String Value objects (PCV 1-20: room labels, user-defined names and units, audit trail strings, technical support ID and banner texts) are typed as proprietary objects in the property tables and are left out here.
- The list also has notification classes NC 1-4 and event enrollments EE 1-4 for primary and secondary room pressure warning and alarm.
- Pressure units follow BV 2 / BV 3 and temperature units BV 4 / BV 10; the analog objects carry no fixed units in the document.
- The summary table describes AV 7 as the negative-mode limit; its name and the property page say positive pressure.
- The document does not state the data link (BACnet IP or BACnet MS/TP).
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 SRCM Room Condition Monitor (two-room) and exports what it actually has to Excel — free.

Questions about the Setra SRCM Room Condition Monitor (two-room)
How many BACnet points does the Setra SRCM Room Condition Monitor (two-room) have?
This list has 100 BACnet objects: 8 analog inputs, 42 analog values, 1 binary input, 20 binary values, 1 multi-state input, 28 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Setra SRCM Room Condition Monitor (two-room) BACnet points are writable?
48 of the 100 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 Setra SRCM Room Condition Monitor (two-room) BACnet documentation?
Setra does not publish it on its own website. This list comes from SRCM BACnet Object List, a copy hosted by Kele at https://assets.kele.com/Catalog/19%20Pressure/PDFs/SRCM%20BACnet%20Objects%20List.pdf. Ask Setra or its representative for the current revision.
What are the minimum BACnet points to integrate the Setra SRCM Room Condition Monitor (two-room)?
Start with MV 2 Primary Room Pressure Mode (Primary isolation mode: 1 pos, 2 neg, 3 neutral); MV 29 Room Occupancy Status (Occupancy: 1 = Active, 2 = Standby); AI 1 Primary Pressure (Primary room differential pressure); AI 2 Secondary Pressure (Secondary room differential pressure); AI 3 Primary Temperature (Primary room temperature); AI 5 Primary Humidity (Primary room humidity); MI 1 System Operation Status (Room state: normal, door, warning, alarm, ACH); BI 1 Digital Input Status (Door or valve contact); MV 8 Pressure Alarm status (Which room is in pressure alarm); BV 1 Relay Status (Alarm relay state).
Can the BMS supply sensor values to the Setra SRCM Room Condition Monitor (two-room)?
Temperature, humidity and user-defined inputs can take their value from BACnet: set the matching input source MV (17, 19, 21, 23, 25, 27) to 3 = BACnet. The document does not say which object the BMS writes the value to.
How do I check these points on the real SRCM Room Condition Monitor (two-room)?
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.
