Chapter 1 General
The Universal Interfaces can install to be system with KNX bus and other device, which are mainly
use in building control system. The functions are both simple to operate and intuitive, users can program
it according to the requirement to implement the function systematically.
This manual provides technical information about the Universal Interfaces in detail for users as well
as assembly and programming, and explains how to use the Universal Interfaces by the application
examples.
1.1. Product and functional overview
The Universal Interfaces achieve the functional applications via conventional push buttons/switches,
communicate by technical binary, which are used to control the devices such as the Dimmer Actuator/the
Switch Actuator, to control domestic appliance indirectly. At the same time, they also enable the control
of LEDs. The extremely compact design enables the device to be inserted in a conventional 80mm or
86mm wiring box.
The Universal Interfaces connect to the bus though the KNX connection terminals and have no use
for additional supply voltage. It is available to assign the physical address and set the parameters by
Engineering design tools ETS with VD4 (higher than edition ETS3).
The Universal Interfaces have many functions that can be used in a wide variety of application
areas. The following list provides an overview:
Switching and dimming function.
Control of blinds and shutters.
Sending of values e.g. temperature values、water line.
Recalling and storing of scenes.
Trigger an LED for reporting an operation.
Operation of various loads by multiple push button actions.
Operation of several loads in a fixed switching sequence.
Standard counting and differential counting.
Each channel of a device can adopt any of the functions described above.

The following functions can be set separately for each input:
Switch sensor: For switching the lighting or scanning a floating contact; Distinction between
short/long operation and cyclical sending of the contact state are possible.
Switch/dimming sensor: For switching/dimming the lighting; There are start/stop dimming and
stepwise dimming, as well as dimming via a single push button are possible.
Value/Forced operation: For sending the valued of different data types(e.g. temperature values). It
is possible to send different values or data types for short/long operation, possible to activate/deactivate
the forced operation of actuators.
Control scene: For recalling and storing the states of several actuator groups. The actuator groups
can either be controlled via max. 5 individual objects or via an 8 bit scene object.
Switching sequence: For the operation of several actuator groups in a preselected sequence, e.g. the
latching relay.
Counter: For counting input pulses. Various data types of the counter can be set. It is able to set the
counting rate, whether to sending the current counting values cyclically and the differential counter when
enables an additional counter. The differential counter can be reset and run out in report, thereby, it is
convenient to count the daily consumption.
Push button with multiple operations: For triggering various functions depending on the
frequency of the operation. A long operation can also be detected and a function can be triggered.
Shutter sensor: For movement and adjustment of a shutter or blind. Eight present operation modes
are possible in total.
Control LED: For controlling a light-emitting diode, switching and flashing. As the switch, it is with
time limit that turns off automatically after a preset time; as the flash, it is able to set the flashing rates.

Switching sequence
Counter
Multiple operations
Shutter Control
Parameter “Distinction between long and short operation”
This parameter sets whether the input distinguishes between a short and long operation. If “yes” is
selected, there is a waiting period after the opening/closing of the contact to determine whether the
operation is long or short. Only then is a possible reaction triggered. The following drawing clarifies the
function:
Options:
No
Yes
Note: The long operation in the below chapters are the same with here.
Parameter “Cyclic send Tele. ‘Tele. Switch’”
This parameter is visible if there is no distinction between a short and long operation. It is able to set
whether to send the current value of object “Tele. Switch, X” cyclically on the bus.Options:
No
Always
If switch off
If switch on
If the parameter value “always” is selected, the object sends cyclically on the bus, regardless of its
value is 0 or 1. If the parameter value “if switch off” or “if switch on” is set, only the corresponding object
value is sent cyclically.

Parameter “Reaction on opening the contact (fall edge)”
This parameter is visible if there is no distinction between a short and long operation. It can be set
the operation to open and close the contact.Options:
No action
Off
On
Toggle
Stop cyclic transmission
If the parameter “Toggle” is selected, negate the operation, that means negate the current value. For
example, if “On” is selected, when negate it will carry out “Off” operation. If the parameter “Stop cyclic
transmission” is selected, it will stop the cyclical sending telegram till there is a new object value to be
sent. If the parameter “No action” is selected, it will not implement any operation.

If the parameter “Yes” is selected, it will send the current value of the object “Tele. Switch, X” on the
bus. Only when the value “Toggle” has not been set in either of the two parameters “Reaction on
opening/closing the contact”, the value of the object “Tele. Switch, X” can be send on the bus. If one of
the two parameters has the value “TOGGLE”, no values are sent in general on the bus after bus voltage
recovery. If “No reaction” or “Stop cyclic transmission” is selected, there is no values are sent on the bus
either.
