CoolAutomation CoolMasterNet Daikin outdoor system (PRO) objects - VRV-K (RSEYP8-10KJ) BACnet points list

Updated 12 November 2026

Short answer

With PRO functionality, CoolAutomation gateways publish system-level service data for Daikin VRV-K (RSEYP8-10KJ) outdoor systems over BACnet: type, AirNet address, error code, ambient, heat exchanger, discharge, suction, oil, evaporating and condensing temperatures, inverter frequency, current and temperature, EV openings, operating states, compressor, valve and fan states and retry and drooping-control flags (49 objects). Monitoring only.

This page lists 49 BACnet objects for the CoolAutomation CoolMasterNet Daikin outdoor system (PRO) objects - VRV-K (RSEYP8-10KJ) — 0 of them writable — with each object’s type, instance number, name, engineering units and access.

BMS integration notes: CoolAutomation CoolMasterNet Daikin outdoor system (PRO) objects - VRV-K (RSEYP8-10KJ)

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-K (RSEYP8-10KJ) and exports what it actually has to Excel — free.
