Lochinvar IPW (ProtoNode FPC-N54) BACnet points list
Updated 6 November 2026
Lochinvar's ProtoNode FPC-N54 start-up guide lists only four BACnet objects for the IPW: outlet temperature, inlet temperature and outlet voltage as analog inputs, and a writable setpoint. The IPW talks to the ProtoNode at 19200 baud, unlike the other Lochinvar products in the guide.
This page lists 4 BACnet objects for the Lochinvar IPW (ProtoNode FPC-N54) — 1 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Lochinvar’s own free documentation, linked below.

BMS integration notes: Lochinvar IPW (ProtoNode FPC-N54)
Write the setpoint to AV 4 and read outlet temperature, inlet temperature and outlet voltage.
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 4 | Setpoint | Setpoint command from the BMS | Write |
| AI 1 | Outlet Temperature | Outlet water temperature | Read |
| AI 2 | Inlet Temperature | Inlet water temperature | Read |
| AI 3 | Outlet Voltage | Outlet voltage reading (not described in the guide) | Read |
Enable & remote start
AV 4 Setpoint is the only writable object. The guide gives no enable object.
Network setup
- ProtoNode FPC-N54 to the IPW: Modbus RTU, 19200 baud, no parity, 8 data bits, 1 stop bit.
- Give each unit a unique Node-ID (1-255). BACnet device instance = Node_Offset (default 50,000) + Node-ID.
- BACnet IP or BACnet MS/TP is chosen in the ProtoNode web configurator.
Watch out for
- Access is inferred: the table has no read/write column.
- The guide gives no units or ranges for these four objects.
Lochinvar IPW (ProtoNode FPC-N54) BACnet objects
Type: AI, AO, AV, BI, BO, BV, MI/MO/MV (multi-state) · Access: Read read-only, Write writable, Command writable with a priority array.
Note: the source document has no read/write column, so access here is inferred from the object type (inputs read-only, values writable). Confirm on the live controller before writing.
| Description | States | |||||
|---|---|---|---|---|---|---|
| AImin | 1 | Outlet Temperature | Read | |||
| AImin | 2 | Inlet Temperature | Read | |||
| AImin | 3 | Outlet Voltage | Read | |||
| AVmin | 4 | Setpoint | Write |
No points match these filters.

Integration notes
- Appendix C.8 of the guide (page 53).
- The guide does not describe the IPW product itself; the equipment type is taken from the object list.
- The table has no read/write column, units or states; access is inferred from the N2 type (AO = writable).
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 IPW (ProtoNode FPC-N54) and exports what it actually has to Excel — free. New to BACnet?

Questions about the Lochinvar IPW (ProtoNode FPC-N54)
How many BACnet points does the Lochinvar IPW (ProtoNode FPC-N54) have?
This list has 4 BACnet objects: 3 analog inputs, 1 analog value. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Lochinvar IPW (ProtoNode FPC-N54) BACnet points are writable?
1 of the 4 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 Lochinvar IPW (ProtoNode FPC-N54) BACnet documentation?
The source is ProtoNode FPC-N54 Start-up Guide For Interfacing Lochinvar Products, Appendix C.8 IPW (Document Revision 5.A (Lochinvar 2000594856 Rev A)), revision 2020-06 (effective date), published free by Lochinvar at https://assets.lochinvar.com/damroot/Original/10014/161357100338377_2000594856_Rev%20A%20(ProtoNode%20FPC-N54%20Start-up%20Guide%20for%20Lochinvar).pdf.
What are the minimum BACnet points to integrate the Lochinvar IPW (ProtoNode FPC-N54)?
Start with AV 4 Setpoint (Setpoint command from the BMS); AI 1 Outlet Temperature (Outlet water temperature); AI 2 Inlet Temperature (Inlet water temperature); AI 3 Outlet Voltage (Outlet voltage reading (not described in the guide)).
How do I enable BMS control of the Lochinvar IPW (ProtoNode FPC-N54)?
AV 4 Setpoint is the only writable object. The guide gives no enable object.
How do I check these points on the real IPW (ProtoNode FPC-N54)?
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.
