Updated 12 November 2026

Short answer

With PRO functionality, CoolAutomation gateways publish service data from Samsung DVM S Water HR outdoor units over BACnet: type, operation mode and status, error code, capacity, compressor target, order and current frequencies, temperatures, compressor current, EEV positions and compressor and valve states, plus water temperature, flow control and flow switch (54 objects). Monitoring only.

BMS integration notes: CoolAutomation CoolMasterNet Samsung DVM S Water HR outdoor unit (PRO) objects

Integration in brief

Use these objects to monitor Samsung outdoor equipment only; control stays on the CoolMasterNet indoor-unit objects. Map the outdoor block's VA and trend water temperature, pressures, compressor frequency and error code.

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 Samsung DVM S Water HR 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 Samsung DVM S Water HR outdoor unit (PRO) objects and exports what it actually has to Excel — free.
