Updated 12 November 2026

Short answer

With PRO functionality, CoolAutomation gateways publish service data from LG Multi V III HR master outdoor units over BACnet: type, operation mode, error code, target and current high and low pressure, compression ratio, superheat and subcooling, compressor and fan speeds, EEV positions, refrigerant and outdoor temperatures, inverter currents, voltages and IPM temperatures, and valve and compressor states, plus constant-speed compressor and oil supply temperatures (69 objects). Monitoring only.

This page lists 69 BACnet objects for the CoolAutomation CoolMasterNet LG Multi V III HR 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 LG Multi V III HR master outdoor unit (PRO) objects

Integration in brief

Use these objects to monitor LG outdoor equipment only; control stays on the CoolMasterNet indoor-unit objects. Map the master outdoor unit's VA and trend pressures, compressor speed 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.

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 LG Multi V III HR master outdoor unit (PRO) objects and exports what it actually has to Excel — free.

Where is the official CoolAutomation CoolMasterNet LG Multi V III HR 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 LG Multi V III HR master outdoor unit (PRO) objects?

Start with CSV 257 Mode (Operation mode text); PIV 271 InvTrcFrq (Inverter compressor frequency, Hz); AI 280 AirT (Outdoor air temperature, °C); PIV 263 HiPrsTrc (High pressure, kPa); PIV 264 LoPrsTrc (Low pressure, kPa); AI 284 InvDisT (Inverter compressor discharge temp, °C); PIV 258 Err (Error code).

How do I enable BMS control of the CoolAutomation CoolMasterNet LG Multi V III HR 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 LG Multi V III HR 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.
