1. Presentation

INKNXMIT001I000 allows a complete and natural integration of MITSUBISHI ELECTRIC air conditioners with KNX control systems.

Compatible with all Domestic and Mr. Slim models commercialized by MITSUBISHI ELECTRIC.

Main features:

• Reduced dimensions, quick installation.

• Multiple objects for control and status (bit, byte, characters…) with KNX standard

datapoint types.

• Status objects for every control available.

• Control of the AC unit based in the ambient temperature read by the own AC unit, or in

the ambient temperature read by any KNX thermostat.

• AC unit can be controlled simultaneously by the IR remote control of the AC unit and by

KNX.

• Total Control and Monitoring of the AC unit from KNX, including monitoring of AC unit’s

state of internal variables, running hours counter (for filter maintenance control), and error indication and error code.

• Up to 5 scenes can be saved and executed from KNX, fixing the desired combination of

Operation Mode, Set Temperature, Fan Speed, Vane Position and Remote Controller Lock in any moment by using a simple switching.

2. Connection

The interface comes with a cable (1,9 meters long) for direct connection to the internal control board of the AC indoor unit.

o Connection of the interface to the AC indoor unit:

Disconnect mains power from the AC unit. Open the front cover of the indoor unit in order to have access to the internal control board. In the control board locate the socket connector marked as:

CN92 in Mr. Slim models. or CN105 in rest of models.

Using the cable that comes with the interface, insert one of its connectors, the one installed in the shortest uncovered part, into the socket of the INKNXMIT001I000 marked as AC Unit, and the other connector, the one in the largest uncovered part, into the socket CN92 or CN105 of the AC unit's control board. Fix the INKNXMIT001I000 inside or outside the AC indoor unit depending on your needs, remember that INKNXMIT001I000 must be also connected to the KNX bus. Close the AC indoor unit's front cover again.

Important: Do not modify the length of the cable supplied with the interface, it may

affect to the correct operation of the interface

o Connection of the interface to the KNX bus:

Disconnect power of the KNX bus. Connect the interface to the KNX TP-1 (EIB) bus using the KNX standard connector (red/grey) of the interface, respect polarity. Reconnect power of the KNX bus.

o Connections diagram:

3. Configuration and setup

This is a fully compatible KNX device which must be configured and setup using standard KNX tool ETS.

ETS database for this device can be downloaded from:

https://intesis.com/products/ac-interfaces/mitsubishi-electric-gateways/mitsubishi-electric-domestic-mr.slimand-city-multi-to-knx-interface

Please consult the README.txt file, located inside the downloaded zip file, to find instructions on how to install the database.

Important: Do not forget to select the correct settings of AC indoor unit being

connected to the INKNXMIT001I000. This is in "Parameters" of the device in ETS.

4. ETS Parameters

When imported to the ETS software for the first time, the gateway shows the following default parameter configuration:

Figure 4.1 Default parameter configuration

With this configuration it’s possible to send On/Off (Control_ On/Off), change the AC Mode (Control_ Mode), the Fan Speed (Control_ Fan Speed) and also the Setpoint Temperature (Control_ Setpoint Temperature). The Status_ objects, for the mentioned Control_ objects, are also available to use if needed. Also objects Status_ AC Return Temp and Status_ Error/Alarm are shown.

4.1 General dialog

Inside this parameter’s dialog it is possible to activate or change the parameters shown in the Figure 4.1.

The first field shows the URL where to download the database and the user manual for the product.

4.1.1 Send READs for Control_ objects on bus recovery

When this parameter is enabled, INKNXMIT001I000 will send READ telegrams for the group addresses associated on its Control_ objects on bus recovery or application reset/start-up.

o If set to “no” the gateway will not perform any action. o If set to “yes” all Control_ objects with both Transmit (T) and Update (U) flags

enabled will send READs and their values will be updated with the response when received.

Figure 4.3 Parameter detail

➢ Delay before sending READs (sec):

With this parameter, a delay can be configured between 0 and 30 seconds for the READs sent by the Control_ objects. This is to give time enough to other KNX devices on the bus to start-up before sending the READs.

4.1.2 Enable comm obj “Ctrl_ Remote Lock”:

If set to “no” the object will not be shown.

If set to “yes” the Control_ Lock Remote Control object will appear.

• When a “1” value is sent to this communication object, the remote controller is

locked. To be unlocked a “0” value must be sent. The gateway remembers the last value received even if a KNX bus reset/failure happens.

Important: If an initial scene is enabled and it has as Value for Remote Lock

(unchanged) or unlocked, this would unlock the remote controller because the initial scene has priority over the Control_ Lock Remote Control communication object.

4.1.3 Enable func “Control_ Lock Control Obj”

This parameter shows/hide the Control_ Lock Control Obj communication object which, depending on the sent value, locks or unlocks ALL the Control_ communication objects except itself.

o If set to “no” the object will not be shown. o If set to “yes” the Control_ Lock Control Objects object will appear.

• When a “1” value is sent to this communication object, all the Control_

objects will be locked. To unlock a “0” value must be sent, as the gateway remembers the last value received even if a KNX bus reset/failure happens.

4.1.4 Enable func “Operating Hours Counter”

This parameter shows/hides the Status_ Operation Hour Counter communication object which counts the number of operating hours for the INKNXMIT001I000.

o If set to “no” the object will not be shown. o If set to “yes” the Status_ Operation Hour Counter object will appear.

• This object can be read and sends its status every time an hour is counted.

The gateway keeps that count in memory and the status is sent also after a KNX bus reset/failure. Although this object is marked as a Status_ object it also can be written to update the counter when needed. To reset the counter should be written a “0” value.

Important: This object comes by default without the write (W) flag

activated. If is necessary to write on it, this flag must be activated.

Important: This object will also return its status, every time a value is

written, only if it’s different from the existing one.

Important: If the stored value is 0 hours, the gateway will not send the

status to KNX.

4.1.5 Enable object “Error Code [2byte]”

This parameter shows/hides the Status_ Error Code communication object which shows the indoor unit errors, if occurred, in numeric format.

o If set to “no” the object will not be shown.
