Fulton Boiler with Siemens LMV3 and Yokogawa UT32A (N54 ProtoNode) BACnet points list
Updated 6 November 2026
Fulton's N54 ProtoNode reads the boiler's Siemens LMV3 burner control and its Yokogawa UT32A temperature controller over Modbus and publishes 30 objects per boiler. Objects 1-28 are the same burner data as the LMV3-only sheet; 29-30 add the outlet temperature and a writable setpoint from the UT32A.
This page lists 30 BACnet objects for the Fulton Boiler with Siemens LMV3 and Yokogawa UT32A (N54 ProtoNode) — 4 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Fulton’s own free documentation, linked below.

BMS integration notes: Fulton Boiler with Siemens LMV3 and Yokogawa UT32A (N54 ProtoNode)
Put the boiler in remote with the Modbus Mode BV, then run it with Operating Mode In Remote (Auto/On/Off) and the Remote Firing Rate, or write the temperature setpoint to the Yokogawa controller. Monitor burner phase, firing rate, outlet temperature, the alarm output and the LMV error code.
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 1027 | Boiler 1 Operating Mode In Remote | Run command in remote: 0 = Auto, 1 = On, 2 = Off | Write |
| BV 1026 | Boiler 1 Modbus Mode | Set 1 = Remote so network commands take effect | Write |
| AV 1028 | Boiler 1 Remote Firing Rate | Firing rate command, %; 20 % minimum to enable | Write |
| AV 1030 | Boiler 1 Current Setpoint | Temperature setpoint, 0-250 °F | Write |
| BI 1014 | Boiler 1 Controller On/Off Status | Burner controller on/off state | Read |
| AI 1001 | Boiler 1 Burner Control Phase | Burner sequence phase; 60 = operation, 0 = lockout | Read |
| AI 1029 | Boiler 1 Outlet Temperature | Outlet water temperature, °F | Read |
| AI 1005 | Boiler 1 Firing Rate | Actual firing rate, % | Read |
| BI 1020 | Boiler 1 Alarm Status | Boiler alarm active | Read |
| AI 1010 | Boiler 1 Current Error: Error Code | Active LMV error code | Read |
Enable & remote start
Write BV (X)026 Modbus Mode = 1 (Remote). In remote, AV (X)027 Operating Mode In Remote selects 0 = Auto, 1 = On or 2 = Off, and AV (X)028 Remote Firing Rate sets the rate; the boiler is only enabled at 20 % or more. AV (X)030 Current Setpoint is the writable temperature setpoint.
Network setup
- Object ID = boiler Modbus address followed by the three-digit point number: (X)001-(X)030. Boiler 1 = 1001-1030.
- The LMV3 sits at Modbus address X and the Yokogawa UT32A at X+10 on the ProtoNode.
- The sheet gives no device instance, MAC address or baud rate; those are set on the ProtoNode gateway.
Watch out for
- A remote firing rate below 20 % does not enable the boiler.
- Error code points need the Siemens LMV manual to decode.

Integration notes
- Object IDs are written (X)001-(X)030, where (X) is the LMV3's Modbus address. This list shows address 1 (1001-1030).
- The sheet says the Yokogawa control sits at Modbus address X+10 but still prints its two objects as (X)029 and (X)030.
- The sheet does not say which BACnet transport the gateway is set to; ProtoNode gateways are normally configured for BACnet IP or BACnet MS/TP.
- Objects (X)001-(X)028 match the LMV3-only N54 sheet already in the library (fulton/lmv3-protonode-n54).
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 Boiler with Siemens LMV3 and Yokogawa UT32A (N54 ProtoNode) and exports what it actually has to Excel — free.

Questions about the Fulton Boiler with Siemens LMV3 and Yokogawa UT32A (N54 ProtoNode)
How many BACnet points does the Fulton Boiler with Siemens LMV3 and Yokogawa UT32A (N54 ProtoNode) have?
This list has 30 BACnet objects: 14 analog inputs, 3 analog values, 12 binary inputs, 1 binary value. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Fulton Boiler with Siemens LMV3 and Yokogawa UT32A (N54 ProtoNode) BACnet points are writable?
4 of the 30 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 Fulton Boiler with Siemens LMV3 and Yokogawa UT32A (N54 ProtoNode) BACnet documentation?
The source is Hydronic LMV 3 and Yokogawa - Fulton N54 ProtoNode BACnet Network Addressing, revision 2020-04-08 (file date), published free by Fulton at https://fulton.com/app/uploads/2021/02/N54-LMV3-UT32A-BACnet-list_2020-0408.pdf.
What are the minimum BACnet points to integrate the Fulton Boiler with Siemens LMV3 and Yokogawa UT32A (N54 ProtoNode)?
Start with AV 1027 Boiler 1 Operating Mode In Remote (Run command in remote: 0 = Auto, 1 = On, 2 = Off); BV 1026 Boiler 1 Modbus Mode (Set 1 = Remote so network commands take effect); AV 1028 Boiler 1 Remote Firing Rate (Firing rate command, %; 20 % minimum to enable); AV 1030 Boiler 1 Current Setpoint (Temperature setpoint, 0-250 °F); BI 1014 Boiler 1 Controller On/Off Status (Burner controller on/off state); AI 1001 Boiler 1 Burner Control Phase (Burner sequence phase; 60 = operation, 0 = lockout); AI 1029 Boiler 1 Outlet Temperature (Outlet water temperature, °F); AI 1005 Boiler 1 Firing Rate (Actual firing rate, %); BI 1020 Boiler 1 Alarm Status (Boiler alarm active); AI 1010 Boiler 1 Current Error: Error Code (Active LMV error code).
How do I enable BMS control of the Fulton Boiler with Siemens LMV3 and Yokogawa UT32A (N54 ProtoNode)?
Write BV (X)026 Modbus Mode = 1 (Remote). In remote, AV (X)027 Operating Mode In Remote selects 0 = Auto, 1 = On or 2 = Off, and AV (X)028 Remote Firing Rate sets the rate; the boiler is only enabled at 20 % or more. AV (X)030 Current Setpoint is the writable temperature setpoint.
How do I check these points on the real Boiler with Siemens LMV3 and Yokogawa UT32A (N54 ProtoNode)?
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.
