CoolAutomation CoolMasterNet Toshiba SMMS-Mini outdoor unit (PRO) objects BACnet points list

Updated 12 November 2026

Short answer

With PRO functionality, CoolAutomation gateways publish service data from Toshiba SMMS-Mini outdoor units over BACnet: unit HP, compressor speed, fan mode, high and low pressure, discharge, heat exchanger, liquid, suction, outdoor, oil and heat sink temperatures, check codes, compressor current, MCU version, PMV positions and valve states (28 objects). Monitoring only.

This page lists 28 BACnet objects for the CoolAutomation CoolMasterNet Toshiba SMMS-Mini 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 Toshiba SMMS-Mini outdoor unit (PRO) objects

Integration in brief

Use these objects to monitor Toshiba outdoor equipment only; control stays on the CoolMasterNet indoor-unit objects. Map the outdoor block's VA and trend pressures, compressor speed and check 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 Toshiba SMMS-Mini outdoor unit (PRO) objects and exports what it actually has to Excel — free.
