1 Description
Introduction
This document describes the integration of Mitsubishi Heavy Industries air conditioning systems into BACnet
compatible devices and systems using the MH-RC-BAC-1 gateway.
The aim of this integration is to monitor and control your Mitsubishi Heavy Industries air conditioning system,
remotely, from your Control Center using any commercial SCADA or monitoring software that includes a BACnet
driver, or connect it to other BACnet devices to do any automation. To do it so, IntesisBox allows BACnet
communication allowing polling or subscription requests (COV).
IntesisBox makes available the Mitsubishi Heavy Industries air conditioning system indoor units through independent
BACnet objects.
Abstraction of Mitsubishi Heavy Industries air conditioning system properties and functionalities as fixed BACnet
Objects. IntesisBox allows fixed BACnet object IDs mapping. Simple configuration is needed: just select the
appropriate communication parameters (MAC address, baud rate…).
This document assumes that the user is familiar with BACnet and Mitsubishi Heavy Industries technologies and their
technical terms.

Functionality
IntesisBox continuously reads the Mitsubishi Heavy Industries AC system and keeps the updated status of all objects
in its memory, ready to be served when requested from the BACnet side.
The role of IntesisBox consists in associate the elements of the Mitsubishi Heavy Industries AC system with BACnet
objects.
The control of the indoor units through the MH-RC-BAC-1 is permitted, so commands towards the Mitsubishi Heavy
Industries AC units are permitted too.
The indoor unit is offered in a set of BACnet objects and extra functionalities.
Capacity of IntesisBox
IntesisBox is capable of integrating one or more Mitsubishi Heavy Industries AC units and its associated elements.
Element
Max.
Notes
Number of indoor units
1*
Number of indoor units that can be controlled through
IntesisBox
Number of Objects
32
Number of Mitsubishi Heavy Industries AC signals available as
objects into IntesisBox.
* NOTE: Keep in mind that more than one unit can be connected to the same MH-RC-BAC-1 gateway. You can control then more than one AC
unit, but it will be actuated as a single unit. Different commands to different AC units connected to the same MH-RC-BAC-1 will not be allowed.
Quick Setup
1. Install IntesisBox in the desired installation site (DIN rail mounting inside a metallic industrial cabinet
connected to ground is recommended).
2. Connect the communication cables. Details in section 5.3.29.
3. Connect to the IntesisBox. Details in section 7.5.
4. (Optional) Configure the IntesisBox using the configuration tool. Details in section 7.5.2.
5. Check the BACnet objects list for its integration to your BACnet project. Details in section 5.2.
6. Check if there is communication between BACnet and AC system. Details in section 7.5.3.
7. The IntesisBox is ready to be used in your system.
