Cleaver-Brooks HSC Pump Interface Module (ProtoNode) BACnet points list
Updated 7 November 2026Unofficial source
The ProtoNode maps the HSC pump interface module to BACnet: input and output words, pump count, scaled analog inputs, PID process variable, setpoint and output, lead/lag pump numbers and pump run/auto inputs and outputs. Three AVs take a remote setpoint, a modulation override and a heartbeat.
This page lists 47 BACnet objects for the Cleaver-Brooks HSC Pump Interface Module (ProtoNode) — 3 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from a copy of Cleaver-Brooks’s documentation hosted by watmfg.com, not by Cleaver-Brooks itself, so treat it as unofficial.

BMS integration notes: Cleaver-Brooks HSC Pump Interface Module (ProtoNode)
Write the remote setpoint (AV 1) and keep the heartbeat (AV 3) updated. Read the run request, pump run outputs, PID process variable and the alarm output.
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 1 | Remote Setpoint Write | Remote setpoint | Write |
| AV 3 | Heartbeat Write Tag | Heartbeat written by the BMS | Write |
| BI 9 | Pump Run Request | Pump run request | Read |
| BI 17 | Pump 1 Run Output | Pump 1 run output | Read |
| AI 7 | PID PV Scaled Value | PID process variable | Read |
| BI 21 | Alarm Output | Alarm output | Read |
Heartbeat & communication loss
AV 3 Heartbeat Write Tag is written by the BMS; the guide does not state the timeout.
Network setup
- BACnet Device Instance = the controller's Modbus Node-ID + Node_Offset (default 50,000), so Node-ID 1 = 50001. Change Node_Offset in the ProtoNode web configurator to pick other instances.
- The ProtoNode RER does BACnet MS/TP or BACnet IP, selected on its S bank DIP switches.
- BACnet MS/TP: one MAC address (1-127) for the whole ProtoNode on the A bank DIP switches; baud on B0-B3 (38400 factory default).
- BACnet IP: default ProtoNode address 192.168.1.24; change it in the web configurator.
Cleaver-Brooks HSC Pump Interface Module (ProtoNode) 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.

Integration notes
- Each Cleaver-Brooks controller on the ProtoNode is its own BACnet device; the object instances below are the same on every device.
- The guide prints no write-point stars for this profile; the AV/BV objects map to Metasys N2 outputs and Modbus output registers or coils, so they are taken as writable. Access is inferred from object type.
- The guide gives no engineering units or state texts; units appear only where the object name carries them (DEG F / DEG C).
- Where a description is filled in, it gives the register from the guide's Modbus column.
- BIs named after a register and bit (e.g. 30021_9) are spare bits in the profile.
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 HSC Pump Interface Module (ProtoNode) and exports what it actually has to Excel — free.

Questions about the Cleaver-Brooks HSC Pump Interface Module (ProtoNode)
How many BACnet points does the Cleaver-Brooks HSC Pump Interface Module (ProtoNode) have?
This list has 47 BACnet objects: 12 analog inputs, 3 analog values, 32 binary inputs. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Cleaver-Brooks HSC Pump Interface Module (ProtoNode) BACnet points are writable?
3 of the 47 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 Cleaver-Brooks HSC Pump Interface Module (ProtoNode) BACnet documentation?
Cleaver-Brooks does not publish it on its own website. This list comes from Cloud Enabled ProtoNode Gateway Startup Guide (RER/LER) for interfacing Cleaver-Brooks products (750-426), revision 03/2018, a copy hosted by watmfg.com at https://watmfg.com/watmfg23082016/wp-content/uploads/2016/09/750-426-ProtoNode-Cloud.pdf. Ask Cleaver-Brooks or its representative for the current revision.
What are the minimum BACnet points to integrate the Cleaver-Brooks HSC Pump Interface Module (ProtoNode)?
Start with AV 1 Remote Setpoint Write (Remote setpoint); AV 3 Heartbeat Write Tag (Heartbeat written by the BMS); BI 9 Pump Run Request (Pump run request); BI 17 Pump 1 Run Output (Pump 1 run output); AI 7 PID PV Scaled Value (PID process variable); BI 21 Alarm Output (Alarm output).
Does the Cleaver-Brooks HSC Pump Interface Module (ProtoNode) need a BACnet heartbeat or have a communication timeout?
AV 3 Heartbeat Write Tag is written by the BMS; the guide does not state the timeout.
How do I check these points on the real HSC Pump Interface Module (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.
