Cleaver-Brooks Falcon Hydronic boiler control (ProtoNode) BACnet points list

Updated 7 November 2026Unofficial source

Short answer

The ProtoNode maps the Falcon hydronic control's Modbus RTU registers to a fixed set of BACnet objects: safety and limit inputs, water and stack temperatures, firing rate, flame signal, burner state, lockout and hold codes, pump status and lead/lag data. The BMS can enable the burner and lead/lag and write the CH and lead/lag setpoints in °F or °C.

This page lists 90 BACnet objects for the Cleaver-Brooks Falcon Hydronic boiler control (ProtoNode) — 7 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 Hydronic boiler control (ProtoNode)

Integration in brief

Enable the burner, write the CH setpoint (°F or °C object), and use the lead/lag enable and setpoint if the boilers run lead/lag. Read burner state, outlet temperature, 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.

Object ID lookup: Cleaver-Brooks Falcon Hydronic 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 Falcon Hydronic 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 Hydronic boiler control (ProtoNode)

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

This list has 90 BACnet objects: 61 analog inputs, 7 analog values, 22 binary inputs. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Cleaver-Brooks Falcon Hydronic boiler control (ProtoNode) BACnet points are writable?

7 of the 90 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 Hydronic 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 Hydronic boiler control (ProtoNode)?

Start with AV 1 BOILER BURNER ENABLE (Burner enable from the BMS); AV 21 BOILER CH SETPOINT DEG F (Central heat setpoint, °F); AV 11 BOILER LEAD/LAG ENABLE (Lead/lag enable); AV 31 BOILER LEAD/LAG SETPOINT DEG F (Lead/lag setpoint, °F); AI 16 BURN_CTL_STATE (Burner control state code); AI 2 OUTLET WATER TEMP DEG F (Outlet water temperature, °F); AI 74 FIRING_RATE_PERCENT (Firing rate, %); BI 8 Alarm (Alarm); AI 17 LOCKOUT_CODE (Lockout code).

How do I enable BMS control of the Cleaver-Brooks Falcon Hydronic boiler control (ProtoNode)?

AV 1 BOILER BURNER ENABLE and AV 11 BOILER LEAD/LAG ENABLE are the BMS enables; AV 21 / AV 41 write the CH setpoint in °F / °C.

How do I check these points on the real Falcon Hydronic 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.
