CoolAutomation CoolMasterNet Midea V6 master outdoor unit (PRO) objects BACnet points list

Updated 12 November 2026

Short answer

With PRO functionality, CoolAutomation gateways publish service data from Midea V6 master outdoor units over BACnet: mode, preheat, oil return and defrost states, system demand, HP, fan steps, high pressure, temperatures, compressor frequencies and currents, discharge temperatures, EXV positions, valve states, error code and superheat (40 objects). Monitoring only.

This page lists 40 BACnet objects for the CoolAutomation CoolMasterNet Midea V6 master outdoor unit (PRO) objects — 0 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from CoolAutomation’s own free documentation, linked below.

BMS integration notes: CoolAutomation CoolMasterNet Midea V6 master outdoor unit (PRO) objects

Integration in brief

Use these objects to monitor Midea outdoor equipment only; control stays on the CoolMasterNet indoor-unit objects. Map the master outdoor unit's VA and trend pressure, compressor frequency and error 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.

Type: AI, AO, AV, BI, BO, BV, MI/MO/MV (multi-state) · Access: Read read-only, Write writable, Command writable with a priority array.

Note: the source document has no read/write column, so access here is inferred from the object type (inputs read-only, values writable). Confirm on the live controller before writing.

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 CoolMasterNet Midea V6 master outdoor unit (PRO) objects and exports what it actually has to Excel — free.

Questions about the CoolAutomation CoolMasterNet Midea V6 master outdoor unit (PRO) objects

How many BACnet points does the CoolAutomation CoolMasterNet Midea V6 master outdoor unit (PRO) objects have?

This list has 40 BACnet objects: 6 analog inputs, 2 characterstring values, 32 positive integer values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which CoolAutomation CoolMasterNet Midea V6 master outdoor unit (PRO) objects BACnet points are writable?

None of the listed objects are marked writable in the source documentation. The source has no read/write column, so this is inferred from object type.

Where is the official CoolAutomation CoolMasterNet Midea V6 master outdoor unit (PRO) objects BACnet documentation?

The source is BACnet Integration Guidelines - CoolMaster Product Line, CooLinkNet, CooLinkHub, CooLinkBridge, revision Rev 1.0.4, 2026-07-06, published free by CoolAutomation at https://support.coolautomation.com/hc/en-us/article_attachments/38262832368157.

What are the minimum BACnet points to integrate the CoolAutomation CoolMasterNet Midea V6 master outdoor unit (PRO) objects?

Start with PIV 257 Md (Operating mode code); PIV 274 INV1 (Compressor 1 speed, rps); AI 270 T4 (Outdoor ambient temperature, °C); AI 267 HiPrs (High pressure, MPa); PIV 278 T7C1 (Discharge temperature 1, °C); CSV 293 Err (Error code).

How do I enable BMS control of the CoolAutomation CoolMasterNet Midea V6 master outdoor unit (PRO) objects?

BACnet must be enabled on the gateway; these objects belong to its PRO (service data) functionality.

How do I check these points on the real CoolMasterNet Midea V6 master outdoor unit (PRO) 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.
