Cleaver-Brooks Falcon Steam boiler control (ProtoNode) BACnet points list
Updated 7 November 2026Unofficial source
The ProtoNode maps the Falcon steam control's Modbus RTU registers to a fixed set of BACnet objects: safety and limit inputs, steam pressure and setpoints, firing rate, flame signal, burner state, lockout and hold codes and lead/lag data. The BMS can enable the burner and lead/lag and write the steam pressure and lead/lag setpoints.
This page lists 62 BACnet objects for the Cleaver-Brooks Falcon Steam boiler control (ProtoNode) — 5 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 Falcon Steam boiler control (ProtoNode)
Enable the burner and write the steam pressure setpoint; use the lead/lag enable and setpoint if the boilers run lead/lag. Read burner state, steam pressure, firing rate, the alarm input and the lockout code.
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.

Enable & remote start
AV 1 BURNER ENABLE and AV 11 LEAD/LAG_ENABLE are the BMS enables; AV 21 writes the steam pressure setpoint.
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.

Integration notes
- Each Cleaver-Brooks controller on the ProtoNode is its own BACnet device; the object instances below are the same on every device.
- Access follows the guide's write-point stars: the starred AV/BV objects are writable, everything else is 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.
- The source prints the PumpA row (BI 1) twice; it is listed once here.
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 Falcon Steam 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 Falcon Steam boiler control (ProtoNode)
How many BACnet points does the Cleaver-Brooks Falcon Steam boiler control (ProtoNode) have?
This list has 62 BACnet objects: 33 analog inputs, 5 analog values, 24 binary inputs. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Cleaver-Brooks Falcon Steam boiler control (ProtoNode) BACnet points are writable?
5 of the 62 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 Cleaver-Brooks Falcon Steam 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 Falcon Steam boiler control (ProtoNode)?
Start with AV 1 BURNER ENABLE (Burner enable from the BMS); AV 21 STEAM_PRESSURE_SETPOINT (Steam pressure setpoint); AV 11 LEAD/LAG_ENABLE (Lead/lag enable); AV 31 LEAD/LAG_SETPOINT (Lead/lag setpoint); AI 9 BURN_CTL_STATE (Burner control state code); AI 5 STEAM_PRESSURE (Steam pressure); AI 20 FIRING_RATE_PERCENT (Firing rate, %); BI 8 Alarm (Alarm); AI 10 LOCKOUT_CODE (Lockout code).
How do I enable BMS control of the Cleaver-Brooks Falcon Steam boiler control (ProtoNode)?
AV 1 BURNER ENABLE and AV 11 LEAD/LAG_ENABLE are the BMS enables; AV 21 writes the steam pressure setpoint.
How do I check these points on the real Falcon Steam 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.
