CoolAutomation CoolMasterNet Mitsubishi Electric PURY-P ZKMU-A outdoor unit (PRO) objects BACnet points list

Updated 12 November 2026

Short answer

With PRO functionality, CoolAutomation gateways publish service data from Mitsubishi Electric City Multi PURY-P ZKMU-A outdoor units over BACnet: type, control and operation mode, compressor and fan frequencies, total cooling and heating capacity, LEV positions, compressor currents and bus voltage, 63HS/63LS pressures, thermistor, condensing and evaporating temperatures, operation status and OC/OS attribute, plus dual fan data and solenoid valve states (67 objects). Monitoring only.

This page lists 67 BACnet objects for the CoolAutomation CoolMasterNet Mitsubishi Electric PURY-P ZKMU-A 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 Mitsubishi Electric PURY-P ZKMU-A outdoor unit (PRO) objects

Integration in brief

Use these objects to monitor Mitsubishi Electric equipment only; control stays on the CoolMasterNet indoor-unit objects. Map the block's VA and trend operation mode, compressor frequency and pressures.

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 Mitsubishi Electric PURY-P ZKMU-A 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 Mitsubishi Electric PURY-P ZKMU-A outdoor unit (PRO) objects

How many BACnet points does the CoolAutomation CoolMasterNet Mitsubishi Electric PURY-P ZKMU-A outdoor unit (PRO) objects have?

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 Mitsubishi Electric PURY-P ZKMU-A outdoor unit (PRO) objects?

Start with PIV 258 OpeM (Operation mode code); PIV 289 OpeS (Operation status code); BI 314 CompOn (Compressor on); PIV 260 F1 (Compressor 1 frequency, Hz); AI 275 63HS1 (High pressure, kg/cm2); AI 276 63LS (Low pressure, kg/cm2); AI 293 Tc (Condensing temperature, °C); AI 294 Te (Evaporating temperature, °C).

How do I enable BMS control of the CoolAutomation CoolMasterNet Mitsubishi Electric PURY-P ZKMU-A 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 Mitsubishi Electric PURY-P ZKMU-A 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.
