Laars OmniTherm - ProtoNode BACnet points list
Updated 28 October 2026
The ProtoNode reads the OmniTherm control over Modbus RTU and serves 121 objects per unit. Analog inputs cover temperatures, flame signal, 0-10 V inputs and outputs, firing rate, lockout and alarm codes, burner status, history counters and cascade lead/lag states; binary inputs break out the safety chain and output bits. Writable AVs and BVs hold the CH1, CH2, DHW and cascade enables, set points and PID terms plus three demand switches.
This page lists 121 BACnet objects for the Laars OmniTherm - ProtoNode — 28 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Laars’s own free documentation, linked below.

BMS integration notes: Laars OmniTherm - ProtoNode
Enable CH1 with AV 0, set BV 1 CH 1 Demand switch for a call for heat and write the CH1 set point (or the cascade CH set point for a cascade). Read the run contact, Burner Status 2, outlet temperature and firing rate, and watch the alarm contact and lockout 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 0 | CH1 Enable/Disable | CH1 enable (1 = enable) | Write |
| BV 1 | CH 1 Demand switch | CH1 call for heat (1 = heat demand) | Write |
| AV 1 | CH1 Set Point | CH1 water set point | Write |
| AV 27 | Cascade CH Set Point | Set point when units run in cascade | Write |
| BI 11 | Digital Output Status - Run contact | Run output | Read |
| AI 85 | Burner Status 2 | Burner state; 51 = firing, 1 = locked out | Read |
| AI 1 | Outlet sensor | Outlet water temperature | Read |
| AI 33 | Modulating Burner1 Firing rate | Burner 1 firing rate | Read |
| BI 12 | Digital Output Status - Alarm Contact | Alarm output | Read |
| AI 35 | Lockout code | Lockout code (0-29) | Read |
Enable & remote start
AV 0 CH1 Enable/Disable (0 = disable, 1 = enable) and BV 1 CH 1 Demand switch (0 = no heat demand, 1 = heat demand). CH2 and DHW have matching objects.
Network setup
- Device instance = Node_Offset + unit Node-ID. Node_Offset defaults to 50000 and is changed in the ProtoNode web configurator; Node-IDs must be unique, 1-255.
- Unit to ProtoNode: Modbus RTU, 38400 baud, 8 data bits, no parity, 1 stop bit.
- Default ProtoNode IP address 192.168.1.24, mask 255.255.255.0. Choose BACnet IP or BACnet MS/TP with the Protocol Selector, then add one profile per device with its Node-ID.
- With more than one device on a ProtoNode, set BACnet Virtual Server Nodes to Yes. For BACnet MS/TP also set MAC address, baud rate and Max Master.
- Two or more ProtoNodes on the same subnet need different BACnet Network Numbers (default 50).
- A ProtoNode handles 1,500 registers in total; this profile uses 174 per device.
Watch out for
- AI 36 Alarm reason uses codes 30-44, continuing the lockout code list in AI 35.
- PID terms for each circuit are writable AVs; they are tuning values, not BMS commands.

Integration notes
- Each unit on the ProtoNode's RS-485 bus shows up as its own BACnet device, and every one uses the same object IDs. The device instance is Node_Offset (default 50000) plus the unit's Node-ID, so Node-ID 1 = device 50001.
- The mapping has no read/write column. AV, BV and MV objects are mapped to Metasys N2 outputs and LonWorks input variables, so they are listed here as writable; AI, BI and MI objects are read-only.
- The mapping gives no units for temperatures or set points.
- Bit-mapped registers (safety chain, non-safety chain, digital outputs, gas and pilot valve) are split into one BI per bit; the object names here join the register name and the bit label.
- Compared with the MagnaTherm list this one has no DHW recirculation objects but adds the auxiliary 1 output (AI 26) and fan 1 speed (AI 27).
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 OmniTherm - ProtoNode 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 Laars OmniTherm - ProtoNode
How many BACnet points does the Laars OmniTherm - ProtoNode have?
This list has 121 BACnet objects: 72 analog inputs, 25 analog values, 21 binary inputs, 3 binary values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Laars OmniTherm - ProtoNode BACnet points are writable?
28 of the 121 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 Laars OmniTherm - ProtoNode BACnet documentation?
The source is Vendor Protocol Mapping (LAARS Vendor Mappings for the ProtoNode FPC-N34 / FPC-N35) (4404), revision Document Revision 14.B, October 2020, published free by Laars at https://www.laars.com/uploads/products/4404.pdf.
What are the minimum BACnet points to integrate the Laars OmniTherm - ProtoNode?
Start with AV 0 CH1 Enable/Disable (CH1 enable (1 = enable)); BV 1 CH 1 Demand switch (CH1 call for heat (1 = heat demand)); AV 1 CH1 Set Point (CH1 water set point); AV 27 Cascade CH Set Point (Set point when units run in cascade); BI 11 Digital Output Status - Run contact (Run output); AI 85 Burner Status 2 (Burner state; 51 = firing, 1 = locked out); AI 1 Outlet sensor (Outlet water temperature); AI 33 Modulating Burner1 Firing rate (Burner 1 firing rate); BI 12 Digital Output Status - Alarm Contact (Alarm output); AI 35 Lockout code (Lockout code (0-29)).
How do I enable BMS control of the Laars OmniTherm - ProtoNode?
AV 0 CH1 Enable/Disable (0 = disable, 1 = enable) and BV 1 CH 1 Demand switch (0 = no heat demand, 1 = heat demand). CH2 and DHW have matching objects.
How do I check these points on the real OmniTherm - 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.
