3 Description
KNX eTR 205/206 Light push button • Version: 16.12.2020 • Technical changes and errors excepted.
1. Description
The KNX eTR 205/206 Light push button has touch-sensitive buttons with which
functions can be called up in the KNX building bus system. The glass surface is printed
with areas for setting the temperature and light. LEDs are integrated in these areas and
their behaviour can be adjusted.
A temperature sensor is integrated into KNX eTR 205/206 Light. An external tem-
perature reading can be received via the bus and processed with its own data to create
a total temperature (mixed value).
The KNX eTR 205/206 Light has a PI controller for heating and cooling. The setpoint
temperature can be changed using the "+" and "-" touch buttons.
Communication objects can be linked via AND and OR logic gates.
Functions:
•Operating zone for temperature control with 2 areas (warmer, cooler)
•LEDs can be set. All LEDs Off, all LEDs as ambient lighting, all LEDs
individually controllable
•Area function when touching two or more push buttons. Can be configured
as switch, selector switch, as 8 or 16 bit encoder or for scenario recall
•Temperature measurements. Mixed value from own measured value and
external values (proportion can be set by percentage), output of minimum and
maximum values
•PI-controller for heating (one or two-level) and cooling (one or two-level)
according to temperature. Regulation according to separate setpoints or basic
setpoint temperature
•2 AND and 2 OR logic gates each with 4 inputs. 8 logic inputs (in the form
of communications objects) can be used as inputs for the logic gates. The
output from each gate can be configured optionally as 1-bit or 2 x 8-bit
Additional functions KNX eTR 205 Light:
•1 operating zone for light with 2 areas (switching/dimming with short/long
distinction)
Additional functions KNX eTR 206 Light:
•2 operating zones for light with 2 areas (switching/dimming with short/long
distinction)
Configuration is made using the KNX software ETS 5. The product file can be
downloaded from the ETS online catalogue and the Elsner Elektronik website on
www.elsner-elektronik.de in the “Service” menu.
1.0.1. Area function
If the area function in ETS has been activated, another function is available alongside
the regular key functions. This is triggered by touching multiple keys, e.g. if you touch
the sensor with the palm of your hand.

4 Description
KNX eTR 205/206 Light push button • Version: 16.12.2020 • Technical changes and errors excepted.
Using the area function
If a key is pressed and another (different) key is touched within 0.2 seconds, the action
set in the ETS is performed for the area operation (See Fig. 1 a) and b)). The keys are
then blocked for 0.5 seconds.
Using the normal key function
If a key is pressed and no other key is touched within 0.2 seconds, the normal key
function is enabled/provided for 5 seconds (See Fig. 1 c) and d)). This is extended for 5
seconds with each push of the button.
If the area function in the ETS is disabled, the keys can be used normally at any time.

KNX eTR 205/206 Light push button • Version: 16.12.2020 • Technical changes and errors excepted
9. Setting the parameters
9.1. Behaviour on power failure/ restoration of
power
Behaviour following a failure of the bus power supply:
The device sends nothing.
Behaviour on bus restoration of power and following programming or reset:
The device sends all outputs according to their send behaviour set in the parameters
with the delays established in the "General settings" parameter block.
9.2. General settings
Set the basic properties of the data transmission.
9.3. Temperature measured value
Select, whether a malfunction object is to be sent if the sensor is faulty.
Use Offsets to adjust the readings to be sent.
The unit can calculate a mixed value from its own reading and an external value. Set
the mixed value calculation if desired. If an external portion is used, all of the following
settings (threshold values, etc.) are related to the overall reading.

The minimum and maximum readings can be saved and sent to the bus. Use the
"Reset temperature min/max. value" objects to reset the values to the current readings.
The values are not retained after a reset.
9.4. Temperature threshold values
Activate the required temperature threshold values. The menus for the further setting
of the threshold values are then displayed.
9.4.1. Threshold value 1, 2
Threshold value
Decide in which cases threshold values and delay times received are to be kept per
object. The parameter is only taken into consideration if the setting by object is activat-
ed further down. Please note that the setting "After power restoration and program-
ming" should not be used for the initial start-up, as the factory settings are always used
until the first call (setting via objects is ignored).
Set the threshold values directly in the application program using parameters, or de-
fine them via the bus using a communication object.
Threshold value setpoint using parameter:
Set the threshold values and hysteresis directly.
Threshold value setpoint using a communication object:
Beforehand, enter how the threshold value will be received from the bus. Basically, a
new value can be received, or simply a command to increase or decrease.
During initial commissioning, a threshold value must be defined which will be valid un-
til the first call with a new threshold value. For units which have already been taken into
service, the last communicated threshold value can be used. Basically, a temperature
range is given in which the threshold value can be changed (object value limit).
