AAON VCCX-454 Controller BACnet points list

Updated 12 November 2026

Short answer

The VCCX-454 is the unit controller AAON uses on its R-454B equipment. It has an on-board BACnet port that can be set for MS/TP or BACnet IP. The object map has about 350 read-only analog inputs (temperatures, pressures, airflow, RM454 refrigerant module data, power monitor and fan array data), 99 writable analog values (setpoints, overrides and BAS-written sensor values) and about 150 read-only binary inputs (alarms, A2L leak alarms, module and relay status).

This page lists 602 BACnet objects for the AAON VCCX-454 Controller — 99 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from AAON’s own free documentation, linked below.

BMS integration notes: AAON VCCX-454 Controller

Integration in brief

Connect the on-board BACnet port (MS/TP or IP) and set the MAC address, device ID and baud or IP settings on the LCD BACnet screens. The BAS schedules the unit with AV 67 Schedule Force, adjusts the occupied setpoints and supply air setpoints, and can override HVAC mode, fan VFD and OA damper. Alarms are read from the BI objects.

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

Occupancy comes from AV 67 Schedule Force (0 = controller schedule, 1 = forced occupied, 2 = forced unoccupied) or the controller's own schedule. AV 68, AV 69, AV 70 and AV 71 override HVAC mode, fan VFD, OA damper and supply setpoint; writing Auto (0, or 65535 for the VFD overrides) hands control back. AV 98 locks out the compressors.

Sensors & values from the BMS

If the controller is configured for it, the BAS can write AV 72 Space Temperature Value, AV 73 Space Humidity Value, AV 76 Relief Pressure Value, AV 77 Carbon Dioxide Value, AV 78 Outdoor Air Temperature Value and AV 79 Outdoor Air Humidity Value. No refresh timeout is printed in the points table.

Object ID lookup: AAON VCCX-454 Controller 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 VCCX-454 Controller 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 AAON VCCX-454 Controller

How many BACnet points does the AAON VCCX-454 Controller have?

This list has 602 BACnet objects: 351 analog inputs, 99 analog values, 152 binary inputs. The exact set on a given unit depends on its firmware, installed options and configuration.

Which AAON VCCX-454 Controller BACnet points are writable?

99 of the 602 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 AAON VCCX-454 Controller BACnet documentation?

The source is VCCX-454 Controller Technical Guide (ASM07503 Rev. I), revision 2026-08, published free by AAON at https://www.aaon.com/hubfs/Controls%20Literature/VCCX-454%20Technical%20Guide%20Rev.%20I.pdf.

What are the minimum BACnet points to integrate the AAON VCCX-454 Controller?

Start with AV 67 Schedule Force (Occupancy: 0 auto, 1 occupied, 2 unoccupied); AV 1 Occupied Cooling Setpoint (Cooling starts one deadband above this); AV 2 Occupied Heating Setpoint (Heating starts one deadband below this); AV 10 Supply Air Cooling Setpoint (Discharge air target in cooling); AI 3 Control Status (Current occupancy status); AI 4 HVAC Mode (Current operating mode); AI 5 Control Temperature (Reading from the configured control sensor); AI 9 Supply Air Temperature (Discharge air temperature); AI 144 Alarm Status (Summary alarm).

How do I enable BMS control of the AAON VCCX-454 Controller?

Occupancy comes from AV 67 Schedule Force (0 = controller schedule, 1 = forced occupied, 2 = forced unoccupied) or the controller's own schedule. AV 68, AV 69, AV 70 and AV 71 override HVAC mode, fan VFD, OA damper and supply setpoint; writing Auto (0, or 65535 for the VFD overrides) hands control back. AV 98 locks out the compressors.

Can the BMS supply sensor values to the AAON VCCX-454 Controller?

If the controller is configured for it, the BAS can write AV 72 Space Temperature Value, AV 73 Space Humidity Value, AV 76 Relief Pressure Value, AV 77 Carbon Dioxide Value, AV 78 Outdoor Air Temperature Value and AV 79 Outdoor Air Humidity Value. No refresh timeout is printed in the points table.

How do I check these points on the real VCCX-454 Controller?

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.
