Fulton PURE Control - Endura EDR 750-2000 Single (N54 ProtoNode) BACnet points list
Updated 11 November 2026
Fulton's N54 ProtoNode publishes 50 objects for each boiler (one block of objects per boiler), for Endura (EDR) 750-2000 boilers with the PURE control. It covers burner state, modulation, water temperatures, safety switch states, alarms and pump/isolation valve status. The BMS can enable the boiler, send a water setpoint and a heartbeat, and supply outdoor and header values when the boiler is set up for them.
This page lists 50 BACnet objects for the Fulton PURE Control - Endura EDR 750-2000 Single (N54 ProtoNode) — 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 PURE Control - Endura EDR 750-2000 Single (N54 ProtoNode)
Remove the BMS enable jumper at the boiler, write BMS Enable = 1, send the water setpoint to BMS Network Setpoint and keep writing 1 to BMS Heartbeat at least every 10 s. Check that Current Setpoint Mode reads BMS Network (3), then read status, outlet temperature, modulation rate and the alarm points.
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 1057 | Boiler 1 BMS Enable | Network enable; jumper must be removed first | Write |
| AV 1052 | Boiler 1 BMS Network Setpoint | Water temperature setpoint, 40-185 °F | Write |
| AV 1058 | Boiler 1 BMS Heartbeat | Write 1 at least every 10 s for remote operation | Write |
| AI 1051 | Boiler 1 Current Setpoint Mode | Setpoint source; 3 = BMS Network | Read |
| AI 1001 | Boiler 1 LMV Status | Burner phase; 60 = modulating, 0 = lockout | Read |
| AI 1017 | Boiler 1 Outlet Temperature | Outlet water temperature, °F | Read |
| AI 1005 | Boiler 1 Modulation Rate | Actual modulation rate, % | Read |
| AI 1044 | Boiler 1 Active Alarm | Any alarm active (1 = alarm) | Read |
| AI 1043 | Boiler 1 Current Alarm Index | Alarm number from Fulton's alarm chart | Read |
Enable & remote start
Remove the physical jumper at the boiler, then write BV (X)057 BMS Enable = 1. The setpoint comes from AV (X)052 BMS Network Setpoint (40-185 °F); AI (X)051 Current Setpoint Mode reads 3 when the network setpoint is in use.
Heartbeat & communication loss
AV (X)058 BMS Heartbeat: the BMS must write 1 at least once every 10 seconds for remote operation. What the boiler does when the heartbeat stops is not stated on this sheet.
Sensors & values from the BMS
AV (X)025 outdoor air, (X)026 header supply, (X)027 header return and (X)029 DHW temperature are writable only when the boiler program is set to accept that value from the BMS (°F).
Network setup
- Object ID = boiler Modbus address followed by the three-digit point number: (X)001-(X)058. Boiler 1 = 1001-1058, boiler 2 = 2001-2058.
- The sheet gives no device instance, MAC address or baud rate; those are set on the ProtoNode gateway.
Watch out for
- BMS Enable does nothing until the physical jumper is removed.
- Safety BIs mostly read 0 = Fault, 1 = No Fault; the low water BIs read 1 = Fault.

Integration notes
- Object IDs are written (X)001-(X)058, where (X) is the boiler's Modbus address on the ProtoNode. This list shows boiler address 1 (1001-1058); boiler 2 uses 2001-2058.
- 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.
- The BMS Enable point only works after a physical jumper is removed at the boiler.
- Outdoor and header AVs marked Note 1 are writable only when the boiler program is set to take that value from the BMS.
- Current Alarm Index is decoded with Fulton's alarm chart and is only valid while Active Alarm = 1.
- Points 9-16 (VFD and O2 data on the larger Endura+) are left out on this sheet for the EDR 750-2000 hardware.
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 PURE Control - Endura EDR 750-2000 Single (N54 ProtoNode) and exports what it actually has to Excel — free.

Questions about the Fulton PURE Control - Endura EDR 750-2000 Single (N54 ProtoNode)
How many BACnet points does the Fulton PURE Control - Endura EDR 750-2000 Single (N54 ProtoNode) have?
This list has 50 BACnet objects: 27 analog inputs, 6 analog values, 16 binary inputs, 1 binary value. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Fulton PURE Control - Endura EDR 750-2000 Single (N54 ProtoNode) BACnet points are writable?
7 of the 50 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 PURE Control - Endura EDR 750-2000 Single (N54 ProtoNode) BACnet documentation?
The source is Hydronic PURE Per Boiler - Fulton N54 ProtoNode BACnet Network Addressing (Endura EDR 750-2000), revision 2021-08-18 (file date), published free by Fulton at https://fulton.com/app/uploads/2021/02/N54-PURE-EDR750-2MM-Single-BACnet-list_2021_0818.pdf.
What are the minimum BACnet points to integrate the Fulton PURE Control - Endura EDR 750-2000 Single (N54 ProtoNode)?
Start with BV 1057 Boiler 1 BMS Enable (Network enable; jumper must be removed first); AV 1052 Boiler 1 BMS Network Setpoint (Water temperature setpoint, 40-185 °F); AV 1058 Boiler 1 BMS Heartbeat (Write 1 at least every 10 s for remote operation); AI 1051 Boiler 1 Current Setpoint Mode (Setpoint source; 3 = BMS Network); AI 1001 Boiler 1 LMV Status (Burner phase; 60 = modulating, 0 = lockout); AI 1017 Boiler 1 Outlet Temperature (Outlet water temperature, °F); AI 1005 Boiler 1 Modulation Rate (Actual modulation rate, %); AI 1044 Boiler 1 Active Alarm (Any alarm active (1 = alarm)); AI 1043 Boiler 1 Current Alarm Index (Alarm number from Fulton's alarm chart).
How do I enable BMS control of the Fulton PURE Control - Endura EDR 750-2000 Single (N54 ProtoNode)?
Remove the physical jumper at the boiler, then write BV (X)057 BMS Enable = 1. The setpoint comes from AV (X)052 BMS Network Setpoint (40-185 °F); AI (X)051 Current Setpoint Mode reads 3 when the network setpoint is in use.
Does the Fulton PURE Control - Endura EDR 750-2000 Single (N54 ProtoNode) need a BACnet heartbeat or have a communication timeout?
AV (X)058 BMS Heartbeat: the BMS must write 1 at least once every 10 seconds for remote operation. What the boiler does when the heartbeat stops is not stated on this sheet.
Can the BMS supply sensor values to the Fulton PURE Control - Endura EDR 750-2000 Single (N54 ProtoNode)?
AV (X)025 outdoor air, (X)026 header supply, (X)027 header return and (X)029 DHW temperature are writable only when the boiler program is set to accept that value from the BMS (°F).
How do I check these points on the real PURE Control - Endura EDR 750-2000 Single (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.
