CoolAutomation CoolMasterNet Mitsubishi Electric PUHY-P TGMU-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 PUHY-P TGMU-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, subcooling, superheat, condensing and evaporating temperatures and solenoid valve and demand states (44 objects). Monitoring only.

This page lists 44 BACnet objects for the CoolAutomation CoolMasterNet Mitsubishi Electric PUHY-P TGMU-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 PUHY-P TGMU-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.

Object ID lookup: CoolAutomation CoolMasterNet Mitsubishi Electric PUHY-P TGMU-A outdoor unit (PRO) objects point IDs by name

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 PUHY-P TGMU-A outdoor unit (PRO) objects and exports what it actually has to Excel — free.
