Fulton Siemens LMV5 Steam Boiler with BACnet Interface BACnet points list
Updated 6 November 2026
Fulton lists 26 Analog Value objects (integer values) for a steam boiler with a Siemens LMV5 burner control on a BACnet interface. Objects 1-19 are read-only: fuel, output, setpoint, actual pressure, flame signal, units, error code and modes. Objects 20-26 are the writable copies of the mode, output and setpoint values.
This page lists 26 BACnet objects for the Fulton Siemens LMV5 Steam Boiler with BACnet Interface — 7 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 Siemens LMV5 Steam Boiler with BACnet Interface
Write Modbus Mode = Remote (AV 21), then use Operating Mode in Remote (AV 22: Auto, Remote On, Remote Off) and the setpoint or output objects. Read current output, actual pressure, flame signal and the error code. AV 1-19 are read-only copies; the writable versions are AV 20-26.
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 22 | Operating Mode in Remote | 0 = Auto, 1 = Remote On, 2 = Remote Off | Write |
| AV 21 | Modbus Mode | Set 1 = Remote so network commands take effect | Write |
| AV 25 | Setpoint W1 | Steam pressure setpoint W1, psi | Write |
| AV 23 | Predefined Output Modulation (Modulation Rate) | Output in remote, 200-1000 | Write |
| AV 2 | Current Output | Current burner output, % | Read |
| AV 4 | Actual Value / Current Temperature | Actual steam pressure, psi | Read |
| AV 5 | Flame Signal | Flame signal, % | Read |
| AV 9 | Current Error: Error Code | Active LMV error code | Read |
Enable & remote start
AV 21 Modbus Mode = 1 (Remote) hands control to the network; AV 22 Operating Mode in Remote then selects 0 = Auto, 1 = Remote On or 2 = Remote Off. AV 23 Predefined Output Modulation sets the output (200-1000) and AV 24-26 are the writable setpoints W3, W1 and W2.
Network setup
- Object IDs 1-26 are fixed.
- The sheet gives no device instance, MAC address or baud rate.
Watch out for
- Every object is an Analog Value carrying integers, including on/off and mode codes.
- AV 1-19 are read-only; write to AV 20-26 instead.
- Pressure units on the setpoints follow AV 8 Unit of Pressure (0 = bar, 1 = psi); the sheet labels them psi.

Integration notes
- All objects are Analog Values with integer values; on/off and mode values are codes.
- Objects 10 and 11 are printed with the names "35" and "37" and no range; object 11 has no read/write mark (listed here as read-only).
- The sheet does not say which gateway or transport is used.
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 Siemens LMV5 Steam Boiler with BACnet Interface and exports what it actually has to Excel — free.

Questions about the Fulton Siemens LMV5 Steam Boiler with BACnet Interface
How many BACnet points does the Fulton Siemens LMV5 Steam Boiler with BACnet Interface have?
This list has 26 BACnet objects: 26 analog values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Fulton Siemens LMV5 Steam Boiler with BACnet Interface BACnet points are writable?
7 of the 26 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 Siemens LMV5 Steam Boiler with BACnet Interface BACnet documentation?
The source is Network Addressing For Standard Configurations - LMV5 Steam with A BACnet Interface, published free by Fulton at https://fulton.com/app/uploads/2021/03/BACnet_PointsList_LMV5-1.pdf.
What are the minimum BACnet points to integrate the Fulton Siemens LMV5 Steam Boiler with BACnet Interface?
Start with AV 22 Operating Mode in Remote (0 = Auto, 1 = Remote On, 2 = Remote Off); AV 21 Modbus Mode (Set 1 = Remote so network commands take effect); AV 25 Setpoint W1 (Steam pressure setpoint W1, psi); AV 23 Predefined Output Modulation (Modulation Rate) (Output in remote, 200-1000); AV 2 Current Output (Current burner output, %); AV 4 Actual Value / Current Temperature (Actual steam pressure, psi); AV 5 Flame Signal (Flame signal, %); AV 9 Current Error: Error Code (Active LMV error code).
How do I enable BMS control of the Fulton Siemens LMV5 Steam Boiler with BACnet Interface?
AV 21 Modbus Mode = 1 (Remote) hands control to the network; AV 22 Operating Mode in Remote then selects 0 = Auto, 1 = Remote On or 2 = Remote Off. AV 23 Predefined Output Modulation sets the output (200-1000) and AV 24-26 are the writable setpoints W3, W1 and W2.
How do I check these points on the real Siemens LMV5 Steam Boiler with BACnet Interface?
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.
