BMS integration notes: Cleaver-Brooks Hawk 2000 boiler control (ProtoNode)
Read-only. Map load demand, steam pressure or water temperature, setpoint, firing rate, main fuel valve and the burner control and low water alarms.
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.

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.
Watch out for
- Elapsed time and cycle counts appear twice: as two 16-bit word objects and as single objects.

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 profile has only AI and BI objects and the guide marks none as write points, so all are read-only.
- 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.
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 Hawk 2000 boiler control (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 Cleaver-Brooks Hawk 2000 boiler control (ProtoNode)
How many BACnet points does the Cleaver-Brooks Hawk 2000 boiler control (ProtoNode) have?
This list has 75 BACnet objects: 16 analog inputs, 59 binary inputs. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Cleaver-Brooks Hawk 2000 boiler control (ProtoNode) BACnet points are writable?
None of the listed objects are marked writable in the source documentation.
Where is the official Cleaver-Brooks Hawk 2000 boiler control (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 Hawk 2000 boiler control (ProtoNode)?
Start with BI 57 Boiler Load Demand (Boiler load demand); BI 47 Remote Enable Input (Remote enable input); AI 9 Steam Pres or HW Temp (Steam pressure or hot water temperature); AI 7 Set Point - Steam Pres/ Water Temp (Active setpoint); AI 5 Firing Rate (Firing rate); BI 42 Main Fuel (Main fuel valve open); BI 4 Burner Control Alarm (Burner control alarm); BI 3 Lo Water Cutoff (LWCO) (Low water cutoff).
How do I check these points on the real Hawk 2000 boiler control (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.
