Intesis IntesisBox HI-AC-BAC-8 / HI-AC-BAC-64 (Hitachi HC-A8MB / HC-A64MB adaptor) BACnet points list

Updated 12 November 2026Unofficial source

Short answer

An older IntesisBox BACnet IP server that polls one Hitachi HC-A8MB or HC-A64MB adaptor and publishes each indoor unit as a fixed block of 33 objects. HI-AC-BAC-8 handles up to 8 indoor units and HI-AC-BAC-64 up to 64. Instances are (unit number x 100) + offset, so unit 1 uses 101-133. Setup is done with the LinkBoxBACnet tool.

This page lists 35 BACnet objects for the Intesis IntesisBox HI-AC-BAC-8 / HI-AC-BAC-64 (Hitachi HC-A8MB / HC-A64MB adaptor) — 13 of them writable — with each object’s type, instance number, name, engineering units and access. It is re-typed from a copy of Intesis’s documentation hosted by Chipkin Automation Systems, not by Intesis itself, so treat it as unofficial.

BMS integration notes: Intesis IntesisBox HI-AC-BAC-8 / HI-AC-BAC-64 (Hitachi HC-A8MB / HC-A64MB adaptor)

Integration in brief

Connect the IntesisBox to the HC-A8MB/HC-A64MB adaptor and the BACnet IP LAN, set the IP and number of indoor units in LinkBoxBACnet, then map each unit's _command and _status objects from its (unit x 100) block.

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 IntesisBox HI-AC-BAC-8 / HI-AC-BAC-64 (Hitachi HC-A8MB / HC-A64MB adaptor) and exports what it actually has to Excel — free.

Questions about the Intesis IntesisBox HI-AC-BAC-8 / HI-AC-BAC-64 (Hitachi HC-A8MB / HC-A64MB adaptor)

How many BACnet points does the Intesis IntesisBox HI-AC-BAC-8 / HI-AC-BAC-64 (Hitachi HC-A8MB / HC-A64MB adaptor) have?

This list has 35 BACnet objects: 11 analog inputs, 1 analog output, 1 analog value, 4 binary inputs, 1 binary output, 7 binary values, 1 device, 6 multi-state inputs, 3 multi-state outputs. The exact set on a given unit depends on its firmware, installed options and configuration.

Which Intesis IntesisBox HI-AC-BAC-8 / HI-AC-BAC-64 (Hitachi HC-A8MB / HC-A64MB adaptor) BACnet points are writable?

13 of the 35 objects accept a write. Points marked Command have a priority array: a write holds until it is released, so release it back to automatic when you are done.

Where is the official Intesis IntesisBox HI-AC-BAC-8 / HI-AC-BAC-64 (Hitachi HC-A8MB / HC-A64MB adaptor) BACnet documentation?

Intesis does not publish it on its own website. This list comes from IntesisBox BACnet/IP - Hitachi AC User Manual r1.1, revision r1.1 (PICS 2016-11-10), a copy hosted by Chipkin Automation Systems at https://cdn.chipkin.com/assets/uploads/2018/feb/01-01-25-53_intesisbox_hi-ac-bac-8-64_user_manual_en.pdf. Ask Intesis or its representative for the current revision.

What are the minimum BACnet points to integrate the Intesis IntesisBox HI-AC-BAC-8 / HI-AC-BAC-64 (Hitachi HC-A8MB / HC-A64MB adaptor)?

Start with BO 105 IUxxx_OnOff_command (Start/stop indoor unit); MO 107 IUxxx_Mode_command (Mode command); AO 111 IUxxx_Settemp_command (Setpoint command, 17-30 °C); MO 109 IUxxx_Fan_command (Fan speed command (5 = auto)); BI 104 IUxxx_OnOff_status (Run status); AI 110 IUxxx_Settemp_status (Setpoint in use); AI 119 IUxxx_InletTemperature (Return air temperature); BI 101 IUxxx_IU_Exist (Unit found on the adaptor); MI 123 IUxxx_ErrorCode (Alarm code (255 = off)); BI 0 Communication error Hitachi GW (Adaptor communication lost).

How do I enable BMS control of the Intesis IntesisBox HI-AC-BAC-8 / HI-AC-BAC-64 (Hitachi HC-A8MB / HC-A64MB adaptor)?

No enable point is documented. Remote-controller permissions can be locked per unit with the CentralSet BVs (BV 114-118).

How do I check these points on the real IntesisBox HI-AC-BAC-8 / HI-AC-BAC-64 (Hitachi HC-A8MB / HC-A64MB adaptor)?

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.
