BMS integration notes: CoolAutomation CoolMasterNet Daikin outdoor system (PRO) objects - VRV PLUS (RSEYP16-30KJY1)

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 outdoor system (PRO) objects - VRV PLUS (RSEYP16-30KJY1) and exports what it actually has to Excel — free.
