Contemporary Controls Siemens LMV3 burner management via BASgatewayLX BACnet points list

Updated 12 November 2026

Short answer

Gateway profile for the Siemens LMV3: 246 objects (221 AI, 13 AO, 11 BI, 1 BO), 26 polled by default. Polled objects give burner control phase, fuel and air actuator positions, VSD output, fuel type, output, flame signal, throughput, the current error and the input/output states; BO 14 switches the controller on/off. Remote-mode, preselected output and counter registers are unpolled outputs.

This page lists 246 BACnet objects for the Contemporary Controls Siemens LMV3 burner management via BASgatewayLX — 14 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Contemporary Controls’s own free documentation, linked below.

BMS integration notes: Contemporary Controls Siemens LMV3 burner management via BASgatewayLX

Integration in brief

Use Controller on/off (BO 14) for enable; for BMS modulation, enable and set Modbus mode, the remote operating mode and the preselected output. Read phase, output, flame signal and the current error.

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.

Enable & remote start

Controller on/off (BO 14) is polled by default. Remote output control needs Modbus mode (AO 27), the remote operating mode (AO 29) and the preselected output (AO 30), all unpolled in the published profile.

Object ID lookup: Contemporary Controls BASgatewayLX Siemens LMV3 point IDs by name

Integration notes

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 LMV3 burner management via BASgatewayLX 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 Contemporary Controls Siemens LMV3 burner management via BASgatewayLX

How many BACnet points does the Contemporary Controls Siemens LMV3 burner management via BASgatewayLX have?

This list has 246 BACnet objects: 221 analog inputs, 13 analog outputs, 11 binary inputs, 1 binary output. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Contemporary Controls Siemens LMV3 burner management via BASgatewayLX BACnet points are writable?

14 of the 246 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. The source has no read/write column, so this is inferred from object type.

Where is the official Contemporary Controls Siemens LMV3 burner management via BASgatewayLX BACnet documentation?

The source is BASgatewayLX Modbus device profile Siemens_Combustion_Control_LMV3_a (Siemens_Combustion_Control_LMV3_a_LX.csv), published free by Contemporary Controls at https://www.ccontrols.com/support/dp/Siemens_Combustion_Control_LMV3_a_LX.zip.

What are the minimum BACnet points to integrate the Contemporary Controls Siemens LMV3 burner management via BASgatewayLX?

Start with BO 14 Controller on / off (Controller on/off); AO 27 Modbus mode (Modbus mode (local/remote)); AO 30 Preselected target output modulating / multistage (Preselected output in remote mode); AI 1 Burner control phase (Burner control phase); AI 6 Current output (Current output); AI 7 Flame signal (Flame signal); BI 20 Alarm (AL) (Alarm output); AI 10 Current error: Error code (Current error code).

How do I enable BMS control of the Contemporary Controls Siemens LMV3 burner management via BASgatewayLX?

Controller on/off (BO 14) is polled by default. Remote output control needs Modbus mode (AO 27), the remote operating mode (AO 29) and the preselected output (AO 30), all unpolled in the published profile.

How do I check these points on the real Siemens LMV3 burner management via BASgatewayLX?

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.
