Description
Introduction
IntesisTM KNX – Mitsubishi Heavy Industries AC is a communication gateway for the
integration of Mitsubishi Heavy Industries air conditioning (AC) systems into KNX TP-1
(EIB).
This gateway allows integrating a Mitsubishi Heavy Industries AC system inside a
supervision/control/automation system through PLC, SCADA and, in general, through any
device or system with a KNX TP-1 (EIB) interface.
The aim of this integration is to make accessible several Mitsubishi Heavy Industries air
conditioning indoor units communicating with the Superlink protocol as if they were part of
a KNX TP-1 (EIB) system. Therefore, the IntesisTM KNX acts as a KNX device in the KNX TP1 (EIB) interface, allowing the KNX system read and write in the communication objects.
Moreover, IntesisTM includes all hardware required to manage/control Mitsubishi Heavy
Industries indoor units without extra components needed.
Integration signals
Following is the list of parameters that can be monitored/controlled on the indoor units
using IntesisTM:
▪ For each indoor unit in the system:
o Communication Status (read-only)
o On/Off (R/W)
o Operation Mode (R/W)
o SetPoint Temperature (R/W)
o Fan Speed (R/W)
o Remocon Lock/Unlock (R/W)
o Louver Control (R/W)
o Room Temperature (read-only)
o Filter Sign Status (read-only)
o Error Code (read-only)
o Compressor Status (read-only)
o Filter Sign Reset (write-only)
o Remocon Error Reset (write-only)
o Thermo On/Off Status (read-only)
Apart from these, the IntesisTM also implements some extra signals (functions):
▪ For all indoor units
1
in the system:
o HW Communication Status (read-only)
o On/Off (write-only)
o Operation Mode (write-only)
o SetPoint Temperature (write-only)
o Fan Speed (write-only)
o Remocon Lock/Unlock (write-only)
1
These signals work as master signals controlling all connected units at the same time

Functionality
IntesisTM continuously polls (reads) the Superlink network for all configured signals and
keeps the updated status of all of them in its memory ready to be served when requested
from KNX.
When a change of status is detected in a MHI’s AC signal, a write telegram is sent to the
KNX bus, of the associated KNX Group.
When it is received a telegram from the KNX bus, and if its KNX Group address is associated
to an MHI’s AC signal, a message is sent immediately to the Superlink network to perform
the corresponding action in the MHI’s AC system.
In the continuous polling if no response is detected, the corresponding virtual signal inside
the gateway will be activated indicating communication error. There is a virtual signal for
each AC indoor unit indicating communication error with the indoor unit – this signal will be
normally activated if the indoor unit is not properly setup.
Each of the mentioned signals in section 1.2 has to be associated to a KNX group address,
with this, all the system is seen as another KNX device, with the same configuration and
functioning characteristics. These addresses are not fixed and can be configured using the
LinkBoxEIB tool (see 4.2.2)
IntesisTM includes all hardware needed to connect directly with the Mitsubishi Heavy
Industries indoor units connecting with Superlink network.

* There are two different models of IntesisTM KNX – Mitsubishi Heavy Industries AC each
one with different capacity. The table above shows the capacity for the top model (with
maximum capacity).
Their order codes are:
▪ INKNXMHI048O000:
▪ Model supporting up to 48 indoor units
▪ For Superlink-I (Previous Superlink) or Superlink-II (New Superlink).
▪ Indoor Unit actual address range is 00 to 47
▪ INKNXMHI128O000:
▪ Model supporting up to 128 indoor units
▪ For Superlink-II (New Superlink)
▪ Indoor Unit actual address range is 000 to 127
Check available combination of Mitsubishi Heavy Industries Central Control and BMS
interface units in the next tables.
In the case of SL2NA or SL3NA, it is necessary to erase registration of non-connected indoor
unit. For SL2NA and SL3NA, change is required for the setup deprived of the rights of
instruction of Remocon control Lock/Unlock.

KNX interface of Intesis
TM
Description
IntesisTM KNX - Mitsubishi Heavy Industries supports the KNX TP-1 (EIB) physical layer, as
defined in the KNX standard. It behaves as another device of the KNX system, with the
same configuration and functional characteristics as other KNX devices.
KNX TP-1 (EIB) bus provides a 30V DC current, which can even directly power certain lowconsumption KNX devices. IntesisTM does not drain any significant current from the KNX bus
- it has a separate own power supply. Another important electrical aspect is that the KNX
TP-1 (EIB) port of IntesisTM is optically isolated (~2500Vrms AC) from all its other ports
(EIA232, EIA485, Ethernet) and power supply.
At a logical level, all KNX devices feature an interface of communication objects, by which
their functionality is abstracted. As a basic example, a KNX interface of an AC indoor unit
would typically consist of an interface of datapoints such as “On/Off”, “Setpoint
temperature”, “Operating mode”, etc.
Associations between communication objects from different KNX devices are actually done
by means of so-called group addresses.
KNX telegrams within a working KNX installation are always addressed to a certain KNX
group address. Typically, whenever a communication object on a KNX device changes its
value, the new value is updated to the bus, by sending a “write” telegram addressed to its
associated group address. The rest of KNX devices in the installation that have a
communication object associated to this group address will act accordingly on reception of
the new value.
Other operations are possible. KNX devices can also decide to read the current value of the
communication objects, by sending a “read” telegram to a certain group address (previously
known to be associated to the targeted comm. object). This operation is performed by many
devices on bus start-up or recovery – in this way, the device gets the latest value of the
group addresses it has associated right from its start-up.
Each datapoint defined in IntesisTM KNX configuration needs at least a single KNX group
address associated with it. This group address will be used either for sending updates to
KNX of the datapoint value (that have been generated on the other MHI interface of the
IntesisTM), or receiving updates from KNX of the datapoint value (that will be propagated to
the MHI side in this case)
From the point of view of KNX functionality, each datapoint of IntesisTM can hold following
group address associations:
• A single KNX group address with which update/write telegrams will be sent,
whenever the datapoint changes (as a result of a change coming from the other
interface of IntesisTM, MHI in this case).
• One or more KNX group addresses from which this datapoint of Intesis
TM
will be
updated/written from the KNX installation (resulting in a change to the other side of
IntesisTM, MHI in this case).
A single KNX group address from which IntesisTM will read the object value on KNX bus
recovery / IntesisTM start-up.
