Dwyer Series RSME / RSMC Room Status Monitor BACnet points list
Updated 4 November 2026
Short answer
The RSME/RSMC shows room differential pressure from a built-in sensor and can add two universal inputs (temperature, humidity, pressure or flow), a door/switch input and up to three external BACnet sensors read from other devices. It runs on BACnet MS/TP (or Modbus RTU) and exposes the readings, alarm states, alarm limits, room modes and almost all setup as objects. Up to three rooms can be shown on the display.
This page lists 192 BACnet objects for the Dwyer Series RSME / RSMC Room Status Monitor — 161 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Dwyer’s own free documentation, linked below.

BMS integration notes: Dwyer Series RSME / RSMC Room Status Monitor
Integration in brief
Read the room pressure (AI 1) and its alarm status (MSV 3), plus any universal or external inputs that are in use and their alarm statuses. The BMS can set each room to occupied, unoccupied or cleaning with MSV 36-38, and reset latched alarms with BV 22.
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 36 | Room 1 Mode | Room 1 mode: 1 Occupied, 2 Unoccupied, 3 Cleaning | Write |
| BV 22 | Reset Alarms | Write 1 to reset latched alarms | Write |
| AI 1 | Pressure | Room differential pressure, inWC by default | Read |
| MV 16 | Binary Input Status | Door/switch input status (Door Open/Closed) | Read |
| BV 16 | Relay Status | Alarm relay state | Read |
| MV 3 | Pressure Alarm Status | Pressure alarm: 1 OK, 2 Warning, 3 Alarm | Read |
Enable & remote start
BV 1 Pressure Enable turns monitoring of the built-in sensor on; each universal input and external sensor has its own enable BV.
Sensors & values from the BMS
Up to three external BACnet analog sensors (ES1-ES3) and three digital points (ED1-ED3) are read by the monitor itself: set the remote device instance and object instance (PIV 12/13 for ES1 and so on), the object type, then enable the sensor. The remote device must answer a directed Who-Is. Values appear in AV 26/32/38 and MSV 58/62/66.
Network setup
- BACnet MS/TP or Modbus RTU over 2-wire RS485, chosen in the Network menu (Configuration > Network).
- Optional 120 ohm termination: jumper terminals 9 and 10.
- Default device instance 607127 (vendor ID 607); Max Master default 127.
- DeviceCommunicationControl and ReinitializeDevice need the password given in the manual.
- Time sync from BACnet must be turned on in Maintenance > Date and time.
Watch out for
- No segmentation: the full Object_List cannot be read in one ReadProperty; read it by index.
- Changing MV 1 Pressure Unit changes the units of all pressure limits; COV increments are unit-less and may need adjusting.
- BV 21 Mute and BV 22 Reset act only on writing 1; writing 0 does nothing.
- Most objects are setup values; do not write them cyclically from the BMS.

Integration notes
- Object names come from Table 1 of the manual; access, units and state texts come from the per-object pages (Present Value property access).
- Table 1 and the detail pages disagree on a few names. MSV 16 is printed "Binary Input Alarm Enable" in Table 1 but its detail page, states and siblings (MSV 19, MSV 58) make it the input status, so the detail name "Binary Input Status" is used. BV 11 (detail: "Binary Alarm Enable"), CSV 11 and the MSV 36-38 detail name keep Table 1. The BV 18 text calls Reset Alarms BV21; Table 1 and its own page put it at BV 22.
- AV 18 is printed "U12 Min Scale Value" and AV 41 "ES3 Low Limit"; names are kept as printed.
- Units are defaults: pressure objects follow MV 1 Pressure Unit (default inWC); universal and external sensor values follow their media type and unit setting (default °F); AV 6/7 default to volts for UI1 and AV 15/16 to mA for UI2.
- Multi-state values are typed MSV in the manual and shown here as MV.
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 Series RSME / RSMC Room Status Monitor 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 Dwyer Series RSME / RSMC Room Status Monitor
How many BACnet points does the Dwyer Series RSME / RSMC Room Status Monitor have?
This list has 192 BACnet objects: 3 analog inputs, 43 analog values, 37 binary values, 66 multi-state values, 11 characterstring values, 32 positive integer values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Dwyer Series RSME / RSMC Room Status Monitor BACnet points are writable?
161 of the 192 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 Dwyer Series RSME / RSMC Room Status Monitor BACnet documentation?
The source is Series RSME/RSMC BACnet/Modbus Operating Instructions, published free by Dwyer at https://assets.dwyeromega.com/manuals-do/RSMC_BACnet_and_Modbus_Operation_Instructions.pdf.
What are the minimum BACnet points to integrate the Dwyer Series RSME / RSMC Room Status Monitor?
Start with MV 36 Room 1 Mode (Room 1 mode: 1 Occupied, 2 Unoccupied, 3 Cleaning); BV 22 Reset Alarms (Write 1 to reset latched alarms); AI 1 Pressure (Room differential pressure, inWC by default); MV 16 Binary Input Status (Door/switch input status (Door Open/Closed)); BV 16 Relay Status (Alarm relay state); MV 3 Pressure Alarm Status (Pressure alarm: 1 OK, 2 Warning, 3 Alarm).
How do I enable BMS control of the Dwyer Series RSME / RSMC Room Status Monitor?
BV 1 Pressure Enable turns monitoring of the built-in sensor on; each universal input and external sensor has its own enable BV.
Can the BMS supply sensor values to the Dwyer Series RSME / RSMC Room Status Monitor?
Up to three external BACnet analog sensors (ES1-ES3) and three digital points (ED1-ED3) are read by the monitor itself: set the remote device instance and object instance (PIV 12/13 for ES1 and so on), the object type, then enable the sensor. The remote device must answer a directed Who-Is. Values appear in AV 26/32/38 and MSV 58/62/66.
How do I check these points on the real Series RSME / RSMC Room Status Monitor?
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.
