Fulton Hydronic SOLA Boiler (N54 ProtoNode) BACnet points list
Updated 6 November 2026
Fulton's N54 ProtoNode publishes 41 objects for each hydronic boiler with the SOLA control. They cover water temperatures, active setpoints and operating points, firing rate, fan speed, flame signal, alarm and lockout data, safety input states and pump outputs. The BMS can enable central heat, DHW and lead/lag, send their setpoints, and force the burner on or off with a remote firing rate.
This page lists 41 BACnet objects for the Fulton Hydronic SOLA Boiler (N54 ProtoNode) — 8 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 Hydronic SOLA Boiler (N54 ProtoNode)
Turn central heat on with CH Enable and write the CH setpoint, or let the BMS hold the boiler with Remote Operating Mode and a Remote Firing Rate. Read burner status, outlet temperature, firing rate, the alarm status and the 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 |
|---|---|---|---|
| BV 1032 | Boiler 1 CH Enable | Central heat enable (1 = enable) | Write |
| AV 1033 | Boiler 1 CH Setpoint Input | Central heat setpoint, °F | Write |
| AV 1040 | Boiler 1 Remote Operating Mode | 0 = Auto, 1 = Remote Off, 2 = Remote On | Write |
| AV 1041 | Boiler 1 Remote Firing Rate | Firing rate in remote, 0-100 % | Write |
| AI 1039 | Boiler 1 Burner Status | Burner state code; see states | Read |
| AI 1001 | Boiler 1 Outlet Temperature | Outlet water temperature, °F | Read |
| AI 1013 | Boiler 1 Firing Rate | Actual firing rate, % | Read |
| BI 1016 | Boiler 1 Alarm Status | Alarm active (1 = active) | Read |
| AI 1017 | Boiler 1 Lockout Code | Lockout code; 0 = no lockout | Read |
Enable & remote start
BV (X)032 CH Enable turns central heat on; AV (X)033 CH Setpoint Input sets the CH target. AV (X)040 Remote Operating Mode (0 Auto, 1 Remote Off, 2 Remote On) and AV (X)041 Remote Firing Rate let the BMS force the burner. DHW and lead/lag have their own enable and setpoint objects.
Network setup
- Object ID = boiler Modbus address followed by the three-digit point number: (X)001-(X)041. Boiler 1 = 1001-1041, boiler 2 = 2001-2041.
- The sheet gives no device instance, MAC address or baud rate; those are set on the ProtoNode gateway.
Watch out for
- Lockout codes (1-4096) are decoded with the SOLA control manual.
- The safety input BIs report the circuit (0 = open, 1 = made), not a fault flag; check which way each switch fails.

Integration notes
- Object IDs are written (X)001-(X)041, where (X) is the boiler's Modbus address on the ProtoNode. This list shows boiler address 1 (1001-1041).
- 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.
- Fan Speed range depends on user settings.
- Burner Demand Source and Burner Status are analog inputs carrying a code; the codes are in the states.
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 Hydronic SOLA Boiler (N54 ProtoNode) and exports what it actually has to Excel — free.

Questions about the Fulton Hydronic SOLA Boiler (N54 ProtoNode)
How many BACnet points does the Fulton Hydronic SOLA Boiler (N54 ProtoNode) have?
This list has 41 BACnet objects: 21 analog inputs, 5 analog values, 12 binary inputs, 3 binary values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Fulton Hydronic SOLA Boiler (N54 ProtoNode) BACnet points are writable?
8 of the 41 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 Hydronic SOLA Boiler (N54 ProtoNode) BACnet documentation?
The source is Hydronic SOLA - 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-sola-BACnet-list_2020-0408.pdf.
What are the minimum BACnet points to integrate the Fulton Hydronic SOLA Boiler (N54 ProtoNode)?
Start with BV 1032 Boiler 1 CH Enable (Central heat enable (1 = enable)); AV 1033 Boiler 1 CH Setpoint Input (Central heat setpoint, °F); AV 1040 Boiler 1 Remote Operating Mode (0 = Auto, 1 = Remote Off, 2 = Remote On); AV 1041 Boiler 1 Remote Firing Rate (Firing rate in remote, 0-100 %); AI 1039 Boiler 1 Burner Status (Burner state code; see states); AI 1001 Boiler 1 Outlet Temperature (Outlet water temperature, °F); AI 1013 Boiler 1 Firing Rate (Actual firing rate, %); BI 1016 Boiler 1 Alarm Status (Alarm active (1 = active)); AI 1017 Boiler 1 Lockout Code (Lockout code; 0 = no lockout).
How do I enable BMS control of the Fulton Hydronic SOLA Boiler (N54 ProtoNode)?
BV (X)032 CH Enable turns central heat on; AV (X)033 CH Setpoint Input sets the CH target. AV (X)040 Remote Operating Mode (0 Auto, 1 Remote Off, 2 Remote On) and AV (X)041 Remote Firing Rate let the BMS force the burner. DHW and lead/lag have their own enable and setpoint objects.
How do I check these points on the real Hydronic SOLA Boiler (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.
