CoolAutomation CoolMasterNet LG SUPER5 master outdoor unit (PRO) objects BACnet points list

Updated 12 November 2026

Short answer

With PRO functionality, CoolAutomation gateways publish service data from LG SUPER5 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 (59 objects). Monitoring only.

This page lists 59 BACnet objects for the CoolAutomation CoolMasterNet LG SUPER5 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 SUPER5 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 SUPER5 master outdoor unit (PRO) objects 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 CoolAutomation CoolMasterNet LG SUPER5 master outdoor unit (PRO) objects

How many BACnet points does the CoolAutomation CoolMasterNet LG SUPER5 master outdoor unit (PRO) objects have?

This list has 59 BACnet objects: 21 analog inputs, 10 binary inputs, 2 characterstring values, 26 positive integer values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which CoolAutomation CoolMasterNet LG SUPER5 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 LG SUPER5 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 SUPER5 master outdoor unit (PRO) objects?

Start with CSV 257 Mode (Operation mode text); BI 308 CompOper (Compressor running); PIV 266 Inv1TrcFrq (Inverter compressor frequency, Hz); AI 276 AirT (Outdoor air temperature, °C); PIV 262 HiPrsTrc (High pressure, kPa); PIV 263 LoPrsTrc (Low pressure, kPa); AI 280 Inv1DisT (Inverter compressor discharge temp, °C); PIV 258 Err (Error code).

How do I enable BMS control of the CoolAutomation CoolMasterNet LG SUPER5 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 SUPER5 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.
