CoolAutomation CoolMasterNet Toshiba SMMSe header outdoor unit (PRO) objects BACnet points list

Updated 12 November 2026

Short answer

With PRO functionality, CoolAutomation gateways publish service data from Toshiba SMMSe header outdoor units over BACnet: unit HP, compressor speeds, fan mode, high and low pressure, discharge, heat exchanger, liquid, suction, outdoor and oil temperatures, check codes, compressor currents, PMV positions and valve states, plus IGBT temperatures, heaters and forced-stop flags (57 objects). Monitoring only.

BMS integration notes: CoolAutomation CoolMasterNet Toshiba SMMSe header 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 header unit'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.

Object ID lookup: CoolAutomation CoolMasterNet Toshiba SMMSe header 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 Toshiba SMMSe header outdoor unit (PRO) objects and exports what it actually has to Excel — free.

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 Toshiba SMMSe header outdoor unit (PRO) objects?

Start with AI 259 Comp(1) (Compressor 1 speed, Hz); AI 278 TO (Outdoor air temperature, °C); AI 263 Pd[psi] (High pressure, psi); AI 264 Ps[psi] (Low pressure, psi); AI 265 TD1 (Discharge temperature 1, °C); PIV 287 CheckCd1 (Check (error) code 1).

How do I enable BMS control of the CoolAutomation CoolMasterNet Toshiba SMMSe header 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 Toshiba SMMSe header 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.
