3.1. Introduction

This document describes the integration of Hitachi air conditioning (AC) systems into BACnet or Modbus
installations using the Intesis IN485HIT001R000 gateway.
The aim of this integration is to monitor and control your Hitachi AC system using any BACnet or Modbus
software solution to remotely monitor and control your installation. To do so, the gateway allows BACnet
communication by polling or subscription requests (COV).
The gateway makes Hitachi AC indoor units available through independent BACnet objects/Modbus registers
to set the AC system properties and functionalities. The gateway allows ID mapping of fixed BACnet objects/
Modbus registers. The configuration process is very easy with the built-in DIP switch blocks. For more
information, see Connections and Switches (page
