CoolAutomation CoolMasterNet Daikin VRV outdoor unit (PRO) objects - VRV-2-WATER (RWEYQ10-30MY1) BACnet points list

Updated 12 November 2026

Short answer

With PRO functionality, CoolAutomation gateways publish service data from each Daikin VRV-2-WATER (RWEYQ10-30MY1) water-cooled outdoor unit over BACnet: AirNet address, HP, suction, discharge, coil, subcooling, receiver, evaporating and condensing temperatures, EV openings, inverter frequency, fin temperature and current, compressor, heater, valve and pump states and retry and stepping-down flags (37 objects). Monitoring only.

This page lists 37 BACnet objects for the CoolAutomation CoolMasterNet Daikin VRV outdoor unit (PRO) objects - VRV-2-WATER (RWEYQ10-30MY1) — 0 of them writable — with each object’s type, instance number, name, engineering units and access.

BMS integration notes: CoolAutomation CoolMasterNet Daikin VRV outdoor unit (PRO) objects - VRV-2-WATER (RWEYQ10-30MY1)

Integration in brief

Use these objects to monitor Daikin outdoor equipment only; control stays on the CoolMasterNet indoor-unit objects. Map the block's VA and trend operating states, temperatures, compressor data and the 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 - VRV-2-WATER (RWEYQ10-30MY1) and exports what it actually has to Excel — free.
