1. FUNCTIONAL DESCRIPTION
The KNX universal interface can be configured as 2, 4 or 6 channels depending on the application: ITR102,
ITR104 or ITR106. The application program can be loaded with ETS3 or higher and supports the applications
which will be described in this manual:
-Send switching commands - 1 bit.
-Send toggle commands - 1 bit.
-Dimming –1 bit, 4 bit.
-Shutter/Blind control –1 bit.
-Send a value selected previously –1 byte, 2 byte.
-2-Channed Mode –1 bit, 1 byte, 2 byte.
Most of functions only need one input and therefore each input might be assigned a different function. However
there are also some functions which use two inputs such as “Dimming with 2 buttons” and “Shutter/Blinds with
2 buttons”.
The device also allows configuring some safety general parameters. It is possible to set a time to detect the
presence of the signal when its state changes and to activate a sending of the value “true” periodically when the
device is running.

2. GENERAL PARAMETERS
There are some safety general parameters such as
“Debouncing” and “Module Alive Beacon”. Using
these parameters it is possible to know weather the
device is working correctly.
PARAMETER
DESCRIPTION
VALUES
Debouncing
This function set a common debouncing duration
for every channel. The duration of the selected
option will be used to detect the presence of the
signal to chance its state.
50 ms
100 ms
150 ms
200 ms
250 ms
Module Alive Beacon
This parameter allows sending the value “true”
periodically while the module is running.
Disabled
Enabled
Module Alive Beacon Interval
(sec)1
This parameter determines the Module Alive
Beacon sending period.
3600 (1…65535)
1This parameter is only visible when the parameter “Module Alive Beacon” is set to “Enabled”
The following objects can be used through the general function:
OBJ NAME

TYPE
FLAG
General
Alive Beacon
1 bit
CRT
This object is only visible when the “Module Alive Beacon” function is enabled. Via the group address linked,
the value “true” is sent while the module is running.

3. FUNCTIONS
3.1. SWITCHING
3.1.1. Description
This function is used to send switching values (ON
or OFF). Each time when the push button is pressed
and / or released a telegram is sent. The sent value
with every action will depend on the parameters
configurated.
3.1.2. Parameters
PARAMETER
DESCRIPTION
VALUES
On Press / On Release
This parameter determines the behaviour of the
switching button.
ON / - : when the contact is closed the value “on“
is sent.
OFF / - : when the contact is closed the value
“off“ is sent.
ON / OFF: when the contact is closed the value
“on“ is sent and when the contact is opened the
value “off” is sent.
OFF / ON: when the contact is closed the value
“off“ is sent and when the contact is opened the
value “on” is sent.
- / ON: when the contact is opened the value “on“
is sent.
- / OFF: when the contact is opened the value
“off“ is sent.
ON / -
OFF / -
ON / OFF
OFF / ON
- / ON
- / OFF
Sending Delay (sec)
This parameter set a delay between the action
and the sending of telegram to the bus. Value 0
means the immediate emission of the telegram.
0(0…255)
Emission at Initialization
“Used” option allows sending the current values
of the inputs to the bus when the module is
energized. Otherwise, any telegram will be sent
after first powered on.
Not Used

Periodical Sending
Send Always: The current input value will be
periodically sent to the bus.
Don't Send Periodically

PARAMETER
DESCRIPTION
VALUES
Dont Send Periodically: There will not be any
periodical sending to the bus.
Send While Button Pressing: The current input
value will be periodically sent to the bus while
the contact of the input is closed.
Send While Button Not Pressing: The current
input value will be periodically sent to the bus
while the contact of the input is opened.
Send While Button Not
Pressing
Send Always
Periodical Sending Interval
(sec)1
This parameter determines the sending period
of the current input value.
60 (1…65535)
Locking
This parameter determines if the input can be
locked via an additional locking object or not.
Disabled: This option is disabled.
Lock On Value 0: When the locking
communication object takes the value 0, status
changes at the input are not transmitted.
Lock On Value 1: When the locking
communication object takes the value 1, status
changes at the input are not transmitted.
Disabled
Lock On Value 0
Lock On Value 1
1This parameter is only visible when the parameter “Periodical sending” is set to “Send Always”, “Send While
Button Pressing” or “Send While Button Not Pressing”.
3.1.3. Objects
