CoolAutomation CoolMasterNet Daikin outdoor system (PRO) objects - RXTA-A BACnet points list

Updated 12 November 2026

Short answer

With PRO functionality, CoolAutomation gateways publish system-level service data for Daikin RXTA-A outdoor systems over BACnet: system type, AirNet address, system HP, target evaporating and condensing temperatures, error code and subcode, and cooling, heating, ventilation, thermostat and restart stand-by states (12 objects). Monitoring only.

This page lists 12 BACnet objects for the CoolAutomation CoolMasterNet Daikin outdoor system (PRO) objects - RXTA-A — 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 outdoor system (PRO) objects - RXTA-A

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 and the error code.

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 - RXTA-A and exports what it actually has to Excel — free.
