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.

through the first press, the next value will be “1” and
viceversa. The device is switched on and off
alternately in every press.

3.3. DIMMING
3.3.1. Description
With this function it is possible to dim and switch a
lighting circuit using one or two pushbuttons. There
are two different objects for each function and they
are controlled depending on the duration of the
push button press. A short press is processed as
switching action and the value (1 bit) is sent via
“On/Off” object. Otherwise a longer one is
interpreted as dimming and the value (4 bit) is sent
via “Dimming” object. The minimum period for
detecting a long push button action is
parameterized previously. When the button is
released after a long press a “stop” telegram is sent.
The dimming function can be configured with 1
button or 2 buttons:
Dimming with one button: Just one input is used for
dimming function. Short presses are interpreted as
toggle action (function described above) switching
on and off alternately in every press. For longer
presses the behaviour is similar, each press of the
button sends to the bus 4-bit object with the value
“up” or “down”. If “up” is transmited through the first
long press, the next value will be “down” and
viceversa. The object value can be update via the
bus from others devices thus there is an status
object, only visible with this configuration, which
prevent any incorrect behaviour. This object must
be connected with the state of the actuator via a
group address.
Dimming with two buttons: Two inputs are
necessary for this option. Each input providing the
function of one push button defined as “Up” or
“Down” through the parameter “Direction” . One
input configured as “Up” will send ON and increase
telegrams while another configured as “Down” will
send OFF and decrease telegrams.
3.3.2. Parameters

Selection
This parameter is used to configure whether the

Dimming with 1 Button: when the contact is closed
briefly the inverted value of the status is sent via
“On/Off” object. Otherwise if the the push-button
is pressed longer a dimmer telegram is sent via
“Dimming” object. The dimming telegram can be
“up” or “down”, it depends on the status. When the
button is released after a long press a “stop”
telegram is sent.
Dimming with 2 Buttons: when the contact is
closed briefly the value “on” (corresponding to UP
direction parameter) or “off” (corresponding to
DOWN direction parameter) is sent via “On/Off”
object. Otherwise if the the push-button is pressed

3.4. SHUTTER / BLINDS
3.4.1. Description
The KNX universal interface makes it possible to
control blinds and shutters with one or two buttons.
Shutter/Blinds with one button: You can both raise
and lower the blind with a single push-button. Each
short press will send a value following this
sequence “down”, “start”, “up” and “stop”. The
current direction of movement of the blind, or the
direction of the slat adjustment, always depends on
the previous action. The object value can be update
via the bus line thus there is an status object, which
prevent any incorrect behaviour. This object must
be connected with the state of the actuator via a
group address.
Shutter/Blinds with two buttons: Two inputs are
necessary for this option. With the combination of
both push buttons, the blind can be lowered or
raised with a long push button action, while a short
push button action ends the movement or adjusts
the slats by one step. The minimum period for
detecting a long push button action is
parameterized previously. Each input providing the
function of one push button defined as “Up” or
“Down” through the parameter “Direction” . One
input configured as “Up” will send Up and start
telegrams while another configured as “Down” will
send down and stop telegrams.
