AAON VCCX-454-GH Controller (grow house) BACnet points list
Updated 12 November 2026
The VCCX-454-GH is a version of the VCCX-454 unit controller for indoor agriculture, with grow, dry, fan, cool, heat and purge modes. Its on-board port connects to a BACnet MS/TP network. The object map is much smaller than the standard VCCX-454: about 50 read-only analog inputs, 7 writable analog values, about 100 read-only binary inputs and two multistate input/value pairs for operating mode and HVAC mode.
This page lists 170 BACnet objects for the AAON VCCX-454-GH Controller (grow house) — 9 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-GH Controller (grow house)
Wire the on-board port to the MS/TP trunk and set address, device ID and baud on the LCD. The BAS writes the space temperature and RH setpoints, can supply space temperature and RH through AV 3 and AV 4 (with AV 7 toggled as a keep-alive), and selects operating and HVAC mode through MV 1 and MV 2.
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
MV 1 Operating Mode (1 = off, 2 = operating) and MV 2 HVAC Mode (grow, dry, fan, cool, heat, purge) are the BACnet mode commands; MI 1 and MI 2 report the active values.
Heartbeat & communication loss
When the controller uses BACnet space temperature and RH (AV 3, AV 4), the BAS must keep toggling AV 7 BACnet Alive Toggle. If it does not change for two minutes the controller falls back to its own sensors (if configured) or raises a space sensor failure alarm.
Sensors & values from the BMS
AV 3 Reference Space Temperature and AV 4 Reference Space RH are used when the controller is configured for BACnet space values; keep AV 7 toggling.
Network setup
- MAC address, device ID (up to seven digits) and baud rate are set on the controller's LCD BACnet screens.
- Supported MS/TP baud rates are 9.6K, 19.2K, 38.4K, 57.6K and 76.8K (from the PICS).
Watch out for
- Stop toggling AV 7 and the controller drops the BAS space values after two minutes.

Integration notes
- AI, BI and MI objects are read-only; AV objects are read/write and only AV 3 and AV 4 are sensor values the BAS may write. MV access is not stated; it is shown as writable here because the values mirror the MI points as commands.
- Instances are grouped per refrigeration circuit A-D (analog inputs in blocks from 50, 60, 70 and 80; binary inputs from 70, 90, 110 and 130), so numbering has gaps.
- Points for refrigeration modules, MHGRV reheat, MODGAS and the 12-relay expansion board only report when fitted.
- Source: Appendix C VCCX-454-GH BACnet, guide pages 79-86.
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-GH Controller (grow house) 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-GH Controller (grow house)
How many BACnet points does the AAON VCCX-454-GH Controller (grow house) have?
This list has 170 BACnet objects: 53 analog inputs, 7 analog values, 106 binary inputs, 2 multi-state inputs, 2 multi-state values. The exact set on a given unit depends on its firmware, installed options and configuration.
Which AAON VCCX-454-GH Controller (grow house) BACnet points are writable?
9 of the 170 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. The source has no read/write column, so this is inferred from object type.
Where is the official AAON VCCX-454-GH Controller (grow house) BACnet documentation?

What are the minimum BACnet points to integrate the AAON VCCX-454-GH Controller (grow house)?
Start with MV 1 Operating Mode (Operating mode: 1 off, 2 operating); MV 2 HVAC Mode (HVAC mode: grow, dry, fan, cool, heat, purge); AV 1 Space Temperature Setpoint (Space temperature setpoint, °F); AV 2 Space RH Setpoint (Space RH setpoint, %); MI 1 Mode of Operation (Current operating state: off or operating); MI 2 HVAC Mode (Current HVAC mode); AI 2 Space Temperature (Space temperature); AI 3 Space Humidity (Space humidity); BI 43 Fan Proving Alarm (Main fan airflow failure); BI 45 Emergency Shutdown Alarm (Emergency shutdown active).
How do I enable BMS control of the AAON VCCX-454-GH Controller (grow house)?
MV 1 Operating Mode (1 = off, 2 = operating) and MV 2 HVAC Mode (grow, dry, fan, cool, heat, purge) are the BACnet mode commands; MI 1 and MI 2 report the active values.
Does the AAON VCCX-454-GH Controller (grow house) need a BACnet heartbeat or have a communication timeout?
When the controller uses BACnet space temperature and RH (AV 3, AV 4), the BAS must keep toggling AV 7 BACnet Alive Toggle. If it does not change for two minutes the controller falls back to its own sensors (if configured) or raises a space sensor failure alarm.
Can the BMS supply sensor values to the AAON VCCX-454-GH Controller (grow house)?
AV 3 Reference Space Temperature and AV 4 Reference Space RH are used when the controller is configured for BACnet space values; keep AV 7 toggling.
How do I check these points on the real VCCX-454-GH Controller (grow house)?
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.
