AERCO C-More boilers with ACS / BMS II (ProtoNode RER) BACnet points list

Updated 28 October 2026

Short answer

The AERCO ProtoNode RER reads C-More boiler controllers and an ACS or BMS II sequencer over Modbus RTU and serves them as one BACnet IP or BACnet MS/TP device, using a DIP-selected profile for 4, 8 or 12 C-Mores. This file follows the 12-boiler profile: 11 values per boiler plus 30 plant values from the ACS/BMS II. All objects are analog values; only the network setpoints are writable.

This page lists 162 BACnet objects for the AERCO C-More boilers with ACS / BMS II (ProtoNode RER) — 13 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from AERCO’s own free documentation, linked below.

BMS integration notes: AERCO C-More boilers with ACS / BMS II (ProtoNode RER)

Integration in brief

Set the ProtoNode S-bank DIP switches to the BACnet profile for the number of C-Mores, give each C-More a Comm Address (1-12) and the ACS/BMS II Modbus address 128, then write the setpoint: 03-Net Header Set Temp on the ACS/BMS II for plant control, or each boiler's 03-Net Remote Setpt. The BAS must keep rewriting the setpoint, at least three times per network timeout.

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

No start/stop object. For plant control set the ACS/BMS II to Header Set Mode = Remote Setpt and Remote Signal = Network, then write AV 33. For a single C-More set Boiler Mode = Remote Setpt and Remote Signal = Network, then write its 03-Net Remote Setpt. Monitor-only needs just the Modbus address and 9600 baud.

Heartbeat & communication loss

The BAS must write the setpoint at least three times within the unit's Network Timeout or the unit stops using it. Defaults are 30 s on C-More (5-999 s, Configuration menu), ACS (5-240 s) and BMS II (5-240 s, RS-232 menu).

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. Easy BACnet scans a network for BACnet IP devices from an Android phone, reads every object on the C-More boilers with ACS / BMS II (ProtoNode RER) 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 AERCO C-More boilers with ACS / BMS II (ProtoNode RER)

How many BACnet points does the AERCO C-More boilers with ACS / BMS II (ProtoNode RER) have?

This list has 162 BACnet objects: 162 analog values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which AERCO C-More boilers with ACS / BMS II (ProtoNode RER) BACnet points are writable?

13 of the 162 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 AERCO C-More boilers with ACS / BMS II (ProtoNode RER) BACnet documentation?

The source is AERCO ProtoNode Gateway User Manual (ProtoNode-RER / ProtoNode-LER), GF-129 (OMM-0080_0H), revision 2014-11-06, published free by AERCO at https://www.aerco.com/dfsmedia/0533dbba17714b1ab581ab07a4cbb521/58249-source/637395359810000000/omm-0080-0h-gf-129-protonode-ler-rer-11-06-14.pdf.

What are the minimum BACnet points to integrate the AERCO C-More boilers with ACS / BMS II (ProtoNode RER)?

Start with AV 33 03-Net Header Set Temp (Plant header setpoint via ACS/BMS II, 40-220 °F); AV 24 03-Net Remote Setpt (Boiler 1 network setpoint, 40-220 °F); AV 23 08-Unit Status (Boiler 1 status; 5 = Fault); AV 34 04-Header Temp (Header water temperature, °F); AV 29 06-Outlet Temp (Boiler 1 outlet water temperature, °F); AV 26 01-Fire Rate Out (Boiler 1 fire rate, %); AV 22 07-Display Code (Boiler 1 status/fault message code); AV 36 06-Display Code (ACS/BMS II fault bit field).

How do I enable BMS control of the AERCO C-More boilers with ACS / BMS II (ProtoNode RER)?

No start/stop object. For plant control set the ACS/BMS II to Header Set Mode = Remote Setpt and Remote Signal = Network, then write AV 33. For a single C-More set Boiler Mode = Remote Setpt and Remote Signal = Network, then write its 03-Net Remote Setpt. Monitor-only needs just the Modbus address and 9600 baud.

Does the AERCO C-More boilers with ACS / BMS II (ProtoNode RER) need a BACnet heartbeat or have a communication timeout?

The BAS must write the setpoint at least three times within the unit's Network Timeout or the unit stops using it. Defaults are 30 s on C-More (5-999 s, Configuration menu), ACS (5-240 s) and BMS II (5-240 s, RS-232 menu).

How do I check these points on the real C-More boilers with ACS / BMS II (ProtoNode RER)?

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.
