CoolAutomation CoolMasterNet Samsung DVM S outdoor unit (PRO) objects BACnet points list

Updated 7 November 2026

Short answer

With PRO functionality, CoolAutomation gateways publish service data from Samsung DVM S outdoor units over BACnet: operation mode and status, error code, capacity, power, compressor target/order/current frequencies, high, low and mid pressures, discharge and compressor-top temperatures, currents, EEV positions, fan step and compressor and valve states (49 objects). Monitoring only.

This page lists 49 BACnet objects for the CoolAutomation CoolMasterNet Samsung DVM S 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 Samsung DVM S 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 the key temperatures, compressor data and error state.

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