CoolAutomation CoolMasterNet Mitsubishi Electric CMB-WP/CMB-WM branch controller (PRO) objects BACnet points list

Updated 12 November 2026

Short answer

With PRO functionality, CoolAutomation gateways publish service data from Mitsubishi Electric CMB-WP V-GA1 and CMB-WM V-AA controllers over BACnet: refrigerant, bypass and water outlet temperatures of the heating-main and cooling-main heat exchangers, branch thermistors TH31a-TH31p, high and low pressure, superheat and subcooling, power failure, float switch, debris removal and air vent states, pump speeds, control signals to and from the outdoor unit, total capacities, liquid level controls and 3-way valve positions VB3a-VB3p (70 objects). Monitoring only.

This page lists 70 BACnet objects for the CoolAutomation CoolMasterNet Mitsubishi Electric CMB-WP/CMB-WM branch controller (PRO) objects — 0 of them writable — with each object’s type, instance number, name, engineering units and access.

BMS integration notes: CoolAutomation CoolMasterNet Mitsubishi Electric CMB-WP/CMB-WM branch controller (PRO) objects

Integration in brief

Use these objects to monitor Mitsubishi Electric branch controller equipment only; control stays on the CoolMasterNet indoor-unit objects. Map the block's VA and trend water outlet temperatures, pressures and the power-failure and float switch states.

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 Mitsubishi Electric CMB-WP/CMB-WM branch controller (PRO) objects and exports what it actually has to Excel — free. New to BACnet? Start with what a BACnet points list is and what the object types mean.

Questions about the CoolAutomation CoolMasterNet Mitsubishi Electric CMB-WP/CMB-WM branch controller (PRO) objects

How many BACnet points does the CoolAutomation CoolMasterNet Mitsubishi Electric CMB-WP/CMB-WM branch controller (PRO) objects have?

This list has 70 BACnet objects: 34 analog inputs, 8 binary inputs, 1 characterstring value, 18 integer values, 9 positive integer values. The exact set on a given unit depends on its firmware, installed options and configuration.

Which CoolAutomation CoolMasterNet Mitsubishi Electric CMB-WP/CMB-WM branch controller (PRO) objects BACnet points are writable?

None of the listed objects are marked writable in the source documentation. The source has no read/write column, so this is inferred from object type.

Where is the official CoolAutomation CoolMasterNet Mitsubishi Electric CMB-WP/CMB-WM branch controller (PRO) objects BACnet documentation?

The source is BACnet Integration Guidelines - CoolMaster Product Line, CooLinkNet, CooLinkHub, CooLinkBridge, revision Rev 1.0.4, 2026-07-06, published free by CoolAutomation at https://support.coolautomation.com/hc/en-us/article_attachments/38262832368157.

What are the minimum BACnet points to integrate the CoolAutomation CoolMasterNet Mitsubishi Electric CMB-WP/CMB-WM branch controller (PRO) objects?

Start with AI 273 TH32 (Heating-main HX water outlet temperature); AI 274 TH33 (Cooling-main HX water outlet temperature); AI 277 PS1 (High pressure, liquid side); AI 278 PS3 (Low pressure); IV 305 QjC (Total cooling capacity); IV 306 QjH (Total heating capacity); BI 291 PS (Power failure detected); BI 292 Float (Float switch).

How do I enable BMS control of the CoolAutomation CoolMasterNet Mitsubishi Electric CMB-WP/CMB-WM branch controller (PRO) objects?

BACnet must be enabled on the gateway; these objects belong to its PRO (service data) functionality.

How do I check these points on the real CoolMasterNet Mitsubishi Electric CMB-WP/CMB-WM branch controller (PRO) objects?

Scan the network with a BACnet IP browser such as Easy BACnet, open the device and compare its object list with this table. Anything missing is usually an option that isn't installed or a point that is disabled in the controller's configuration.
