CoolAutomation CoolMasterNet Gree GMV5 outdoor unit (PRO) objects BACnet points list

Updated 11 November 2026

Short answer

With PRO functionality, CoolAutomation gateways publish service data from Gree GMV5 outdoor units over BACnet: rated capacity, master/slave status, outdoor temperature, compressor and fan frequencies, module high and low pressure, discharge, shell, defrost, subcooler and separator temperatures, EXV positions, compressor and valve states, and compressor and fan currents, bus voltages and IPM temperatures (42 objects). Monitoring only.

This page lists 42 BACnet objects for the CoolAutomation CoolMasterNet Gree GMV5 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 Gree GMV5 outdoor unit (PRO) objects

Integration in brief

Use these objects to monitor Gree outdoor equipment only; control stays on the CoolMasterNet indoor-unit objects. Map the outdoor block's VA and trend the key temperatures, pressures and compressor data (the guide lists no error object for Gree outdoor units).

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 Gree GMV5 outdoor unit (PRO) objects and exports what it actually has to Excel — free.

Which CoolAutomation CoolMasterNet Gree GMV5 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 Gree GMV5 outdoor unit (PRO) objects BACnet documentation?

The source is BACnet Integration Guidelines - CoolMasterNet, CooLinkNet, CooLinkHub, CooLinkBridge, revision Rev 0.5, 2019-04-29, published free by CoolAutomation at https://coolautomation.com/Lib/doc/CoolMasterNet/manual/CoolMasterNet-BACnet-guidelines.pdf.

What are the minimum BACnet points to integrate the CoolAutomation CoolMasterNet Gree GMV5 outdoor unit (PRO) objects?

Start with BI 282 Comp1Stat (Compressor 1 running); PIV 265 Comp1OpFreq (Compressor 1 frequency, Hz); IV 264 OutT (Outdoor temperature, °C); IV 269 MdlHp (Module high pressure value); IV 270 MdlLp (Module low pressure value); IV 271 Comp1DisT (Compressor 1 discharge temperature, °C); AI 286 Comp1Cur (Compressor 1 current, A).

How do I enable BMS control of the CoolAutomation CoolMasterNet Gree GMV5 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 Gree GMV5 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.
