Cleaver-Brooks Hawk ICS boiler control (ProtoNode) BACnet points list

Updated 7 November 2026Unofficial source

Short answer

A read-only ProtoNode profile for the Hawk ICS boiler control: alarm and status bits (limits, actuators, flame safeguard, O2, sensor failures), firing-rate modes, flame strength, firing rate, O2, setpoints, steam pressure or water temperature, stack and economizer temperatures, burner status lines, run time and cycles.

This page lists 140 BACnet objects for the Cleaver-Brooks Hawk ICS boiler control (ProtoNode) — 0 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.

Object ID lookup: Cleaver-Brooks Hawk ICS boiler control point IDs by name

Integration notes

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 ICS 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 ICS boiler control (ProtoNode)

How many BACnet points does the Cleaver-Brooks Hawk ICS boiler control (ProtoNode) have?

This list has 140 BACnet objects: 44 analog inputs, 96 binary inputs. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Cleaver-Brooks Hawk ICS 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 ICS 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 ICS boiler control (ProtoNode)?

Start with BI 57 Boiler Load Demand (Boiler load demand); BI 47 Remote enable input (Remote enable input); AI 9 Steam Pressure or HW Temp (Steam pressure or hot water temperature); AI 7 Set Point Steam Pressure/Water Temp (Active setpoint); AI 5 Firing Rate (Firing rate); BI 42 Main Fuel Valve Open (Main fuel valve open); BI 55 Alarm Output (Alarm output); AI 28 Brnr Control Status Line 1 Honeywell (Burner control status line 1 (Honeywell)).

How do I check these points on the real Hawk ICS 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.
