Carrier 40VM Series VRF BACnet Interface 40VM900052A (outdoor header unit objects) BACnet points list
Updated 7 November 2026
Through the 40VM900052A interface, each VRF outdoor header unit appears as its own BACnet device with 20 objects: ambient and discharge temperatures, pressures, compressor and fan speeds, malfunction code, on/off, alarm and mode status, plus system-wide multistate outputs (all off, energy limit, fan speed at zero capacity, dry contact 4 settings) that act on every indoor unit of that system. Follower units show only the 13 inputs.
This page lists 20 BACnet objects for the Carrier 40VM Series VRF BACnet Interface 40VM900052A (outdoor header unit objects) — 7 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from Carrier’s own free documentation, linked below.

BMS integration notes: Carrier 40VM Series VRF BACnet Interface 40VM900052A (outdoor header unit objects)
Read outdoor unit status and diagnostics from the header unit device; the SYS_MO outputs give group commands such as turning off all indoor units of the system (MO 11) or an energy limit level (MO 10).
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 | Name | Why | Access |
|---|---|---|---|

| MO 10 | SYS_MO_AllEnergyLimit | System energy limit level (No Limit, Level 1-5) | Write |

Network setup
- Default IP address of the interface is 192.168.1.8; change it in the web interface.
- Indoor unit addresses are 0-95 and outdoor units 96-127 on each XYE port.
- Each outdoor unit system needs a unique network address 0-7, set with the rotary encoder on the outdoor unit.
Watch out for
- MO 11-16 are write-only group commands; reading them does not reflect indoor unit state.
- Group commands act on every indoor unit of the refrigerant system served by that header unit.
- After writing the energy limit (MO 10), the interface must keep talking to the outdoor unit for at least 1 minute or the limit setting is reported invalid.

Integration notes
- Each outdoor unit is a separate BACnet device; outdoor unit addresses are 96-127 in the NNNPAAA device ID rule.
- Follower outdoor units have the same 13 input objects (AI 1-10, BI 1-2, MI 1) and no outputs.
- The SYS_MO objects are group commands for all indoor units of that refrigerant system and only work on the header unit. MO 11-16 are write-only (the value cannot be read back); MO 10 is readable and writable. MO 14-16 state texts are temperature and time steps, not repeated here.
- Access is inferred: inputs read-only, outputs writable.
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 40VM Series VRF BACnet Interface 40VM900052A (outdoor header unit objects) and exports what it actually has to Excel — free.

Questions about the Carrier 40VM Series VRF BACnet Interface 40VM900052A (outdoor header unit objects)
How many BACnet points does the Carrier 40VM Series VRF BACnet Interface 40VM900052A (outdoor header unit objects) have?
This list has 20 BACnet objects: 10 analog inputs, 2 binary inputs, 1 multi-state input, 7 multi-state outputs. The exact set on a given unit depends on its firmware, installed options and configuration.
Which Carrier 40VM Series VRF BACnet Interface 40VM900052A (outdoor header unit objects) BACnet points are writable?
7 of the 20 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 Carrier 40VM Series VRF BACnet Interface 40VM900052A (outdoor header unit objects) BACnet documentation?
The source is 40VM Series VRF System BACnet Interface Installation and Operation Manual, Part Number 40VM900052A (Table 69, BACnet Object List of Outdoor Header Unit) (40VM-52ASI R1), revision 2023-04, published free by Carrier at https://brandportal.carrier.com/asset/e7209642-8ffc-4f1c-a298-cd0941359add/40VM-52ASI-R1.pdf.
What are the minimum BACnet points to integrate the Carrier 40VM Series VRF BACnet Interface 40VM900052A (outdoor header unit objects)?
Start with MO 11 SYS_MO_AllTurnOff (Group command: turn off/on all indoor units); MO 10 SYS_MO_AllEnergyLimit (System energy limit level (No Limit, Level 1-5)); BI 1 ODU_BI_OnOffStatus (Outdoor unit on/off status); MI 1 ODU_MI_ModeStatus (Outdoor unit mode status); AI 1 ODU_AI_AmbientTemp (Outdoor ambient temperature); BI 2 ODU_BI_Alarm (Outdoor unit alarm indication); AI 8 ODU_AI_MalfunctionCode (Outdoor unit malfunction code).
How do I check these points on the real 40VM Series VRF BACnet Interface 40VM900052A (outdoor header unit objects)?
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.
