CoolAutomation CoolMasterNet Mitsubishi Electric PURY-M YNW-A/A1 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-M YNW-A/A1 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 current, maintenance and preliminary error codes with detail and source address (65 objects). Monitoring only.

This page lists 65 BACnet objects for the CoolAutomation CoolMasterNet Mitsubishi Electric PURY-M YNW-A/A1 outdoor unit (PRO) objects — 0 of them writable — with each object’s type, instance number, name, engineering units and access.

BMS integration notes: CoolAutomation CoolMasterNet Mitsubishi Electric PURY-M YNW-A/A1 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, pressures and error codes.

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-M YNW-A/A1 outdoor unit (PRO) objects and exports what it actually has to Excel — free.
