1 Description
Introduction
This document describes the integration of Hitachi VRF air conditioning systems into KNX home automation systems
using gateway IntesisBox KNX – Hitachi VRF.
The aim of this integration is to monitor and control your Hitachi air conditioning system, from your KNX TP-1 installation.
To do it so, IntesisBox performs as a one more KNX device, sending and receiving telegrams to group addresses in the
KNX network.
IntesisBox makes available the Hitachi air conditioning system indoor units’ datapoints through independent KNX
objects.
Up to 64 indoor units supported, depending on product version.
This document assumes that the user is familiar with KNX and Hitachi technologies and their technical terms.

1.1 Functionality
IntesisBox® continuously monitors Hitachi VRF network for all configured signals and keeps the updated status of all of
them in its memory. It triggers updates on configured group addresses to KNX network on value change.
Commands toward the indoor unit communication adaptor are permitted.
Each indoor unit is offered as a set of KNX objects.

2 KNX System
In this section, a common description for all IntesisBox KNX series gateways is given, from the point of view of KNX
system which is called from now on internal system. Connection with the Hitachi system is also called from now on
external system.
Description
IntesisBox KNX connects directly to the KNX TP-1 bus and performs as one more device into the KNX system, with the
same configuration and operational characteristics as other KNX devices.
Internally, the circuit part connected to the KNX bus is opto-isolated from the rest of the electronics.
IntesisBox KNX receives, manages and sends all the telegrams related to its configuration to the KNX bus.
On receiving WRITE telegrams of KNX group addresses associated to communication objects, the corresponding
messages are sent to the external system (Hitachi installation).
When a change in a signal of the external system is detected, a WRITE telegram is sent to the KNX bus (addressed
with the group address associated to the corresponding group object), in order to maintain both systems synchronized
in every moment.
The status of the KNX bus is checked continuously and, if a bus drop-down is detected, for example due to failure in
the bus power supply, after the KNX bus is restored again, IntesisBox will send READ telegrams to group addresses of
all communication objects marked with flag ‘Ri’. The behavior of each individual point into IntesisBox is determined by
the flags configured for the communication object. See details below.
Points definition
Every group object in configuration has following KNX properties:
Property
Description
Description
Descriptive information about the communication object or signal.
Object
function
Information on range of values for the group object.
DPT
Datapoint type. It is the KNX data type used to encode the signal's value. It will depend
on the type of signal associated in the external system in every case.
Group
It is the KNX group to which the point is associated. It is also the group to which the
read (R), write (W), transmit (T), update (U) and read on init (Ri) flags are applied. It is
the sending group.
Listening
addresses
They are the addresses that can write on the group object, a part of the main group
address.
R
Read. If this flag is activated, READ telegrams of this group address will be accepted.
Ri
Read on Init. If this flag is activated, the object will trigger corresponding READ request
(on associated group address) on initialization.
W
Write. If this flag is activated, WRITE telegrams on this group object will be accepted.
T
Transmit. If this flag is activated, when the group object value changes, due to a change
in the external system, a WRITE telegram of the associated group address will be sent
to the KNX bus.
U
Update. If this flag is activated, UPDATE telegrams (response to READ telegrams) on
this group object will be accepted.
Active
If activated, the point will be active in IntesisBox, if not, the behavior will be as if the
point is not defined. This allows deactivating points without the need of delete them for
possible future use.
These properties are common for all IntesisBox KNX series gateways. Although each integration may have specific
properties according to the type of signals of the external system.
See list of communication objects in section 9 APPENDIX A – COMMUNICATION OBJECTS TABLE.

3 Connections
Find below information regarding the IntesisBox connections available.
Power Supply
Must use NEC Class 2 or Limited Power Source (LPS) and SELV rated
power supply.
If using DC power supply:
Respect polarity applied of terminals (+) and (-). Be sure the voltage
applied is within the range admitted (check table below). The power
supply can be connected to earth but only through the negative
terminal, never through the positive terminal.
If using AC power supply:
Make sure the voltage applied is of the value admitted (24 Vac). Do
not connect any of the terminals of the AC power supply to earth, and
make sure the same power supply is not supplying any other device.
Ethernet
Connect the cable coming from the IP network to the connector ETH of
the gateway. Use an Ethernet CAT5 cable. If communicating through the
LAN of the building, contact the network administrator and make sure
traffic on the port used is allowed through all the LAN path (check the
gateway user manual for more information). Default IP is
192.168.100.246. DHCP is enabled by default.
PortA / KNX
Connect the KNX TP1 bus to connectors A3 (+) and A4 (-) of gateway’s PortA. Respect the polarity.
PortB / H-Link Hitachi
Connect the H-Link terminals (TB2) of Hitachi Outdoor Unit to the connectors B1 and B2 of gateway’s
PortB. There is no polarity to be respected.
Console Port
Connect a mini-type B USB cable from your computer to the gateway to allow communication between the Configuration
Software and the gateway. Remember that Ethernet connection is also allowed. Check the user manual for more
information.
USB
Connect a USB storage device (not a HDD) if required. Check the user manual for more information.
Ensure proper space for all connectors when mounted (see section 6)
