CoolAutomation CoolMasterNet Gree GMV5C outdoor unit (PRO) objects BACnet points list

Updated 12 November 2026

Short answer

With PRO functionality, CoolAutomation gateways publish service data from Gree GMV5C outdoor units over BACnet: rated capacity, protocol versions, outdoor temperature, compressor and fan frequencies, module high and low pressure, discharge, defrost, subcooler and separator temperatures, EXV positions, compressor and valve states and drive currents, voltages and module temperatures (41 objects). Monitoring only.

This page lists 41 BACnet objects for the CoolAutomation CoolMasterNet Gree GMV5C 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 GMV5C 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 compressor, pressure and temperature data.

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 GMV5C outdoor unit (PRO) objects and exports what it actually has to Excel — free.

Questions about the CoolAutomation CoolMasterNet Gree GMV5C outdoor unit (PRO) objects

How many BACnet points does the CoolAutomation CoolMasterNet Gree GMV5C outdoor unit (PRO) objects have?

This list has 41 BACnet objects: 5 analog inputs, 4 binary inputs, 1 characterstring value, 15 integer values, 16 positive integer values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which CoolAutomation CoolMasterNet Gree GMV5C 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 GMV5C 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 Gree GMV5C outdoor unit (PRO) objects?

Start with BI 282 Comp1 (Compressor 1 running); PIV 265 Comp1OpFreq (Compressor 1 frequency, Hz); IV 264 AmbT (Outdoor temperature, °C); IV 269 MdlHiPrs (Module high pressure value); IV 270 MdlLoPrs (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 GMV5C 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 GMV5C 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.
