CoolAutomation CoolMasterNet Daikin VRV outdoor unit (PRO) objects - mini-VRV, VRV-M BACnet points list

Updated 11 November 2026

Short answer

With PRO functionality, CoolAutomation gateways publish service data from each Daikin VRV outdoor unit over BACnet: ambient, suction, evaporating, condensing and discharge temperatures, EV openings, CT and inverter currents, fan step, compressor, heater and valve states, and protection-control flags such as retries and stepping-down or drooping control (55 objects for this series group). Monitoring only.

This page lists 55 BACnet objects for the CoolAutomation CoolMasterNet Daikin VRV outdoor unit (PRO) objects - mini-VRV, VRV-M — 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 Daikin VRV outdoor unit (PRO) objects - mini-VRV, VRV-M

Integration in brief

Use these objects to monitor Daikin 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 Daikin VRV outdoor unit (PRO) objects - mini-VRV, VRV-M and exports what it actually has to Excel — free.
