3 Safety and operating instructions

KNX eTR 208 Light/Sunblind push button • Version: 11.07.2023 • Technical changes and errors excepted.

1. Safety and operating instructions

Installation, testing, operational start-up and troubleshooting should

only be performed by an authorised electrician.

CAUTION!

Live voltage!

• Inspect the device for damage before installation. Only put undamaged

devices into operation.

• Comply with the locally applicable directives, regulations and provisions for

electrical installation.

• Immediately take the device or system out of service and secure it against

unintentional switch-on if risk-free operation is no longer guaranteed.

Use the device exclusively for building automation and observe the operating

instructions. Improper use, modifications to the device or failure to observe the

operating instructions will invalidate any warranty or guarantee claims.

Operate the device only as a fixed-site installation, i.e. only in assembled condition and

after conclusion of all installation and operational start-up tasks, and only in the

surroundings designated for it.

Elsner Elektronik is not liable for any changes in norms and standards which may occur

after publication of these operating instructions.

For information on installation, maintenance, disposal, scope of deliv-

ery and technical data, please refer to the installation instructions.

2. Description

The KNX eTR 208 Light/Sunblind 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, light and solar protection. LEDs are in-

tegrated in these areas and their behaviour can be adjusted.

A temperature sensor is integrated into KNX eTR 208 Light/Sunblind. An external

temperature reading can be received via the bus and processed with its own data to

create a total temperature (mixed value).

The KNX eTR 208 Light/Sunblind 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)

•Operating zone for light with 2 areas (switching and dimming)

4 Description

KNX eTR 208 Light/Sunblind push button • Version: 11.07.2023 • Technical changes and errors excepted.

•Operating zone for blinds, awnings, shutters or windows with 2 areas (up/

down with short/long distinction)

•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

2.0.1. 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.

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.

5 Commissioning

KNX eTR 208 Light/Sunblind push button • Version: 11.07.2023 • Technical changes and errors excepted.

If the area function in the ETS is disabled, the keys can be used normally at any time.

3. Commissioning

Configuration is made using the KNX software as of ETS 5. The product file can be

downloaded from the ETS online catalogue and the Elsner Elektronik website on

www.elsner-elektronik.de.

After the bus voltage has been applied, the device will enter an initialisation phase last-

ing approx. 5 seconds. During this phase no information can be received or sent via the

bus.

4. Addressing the device

The device is delivered ex works with the bus address 15.15.255. You program a differ-

ent address in the ETS by overwriting the address 15.15.255 or teach the device using

the programming button.

The programming button is located at the bottom outer side of the front panel of the

device and is recessed. Use a thin object to reach the button, e. g. a 1.5 mm² wire.

When the button is pressed, the temperature display on the front flashes.

6 Display and operation at the device

KNX eTR 208 Light/Sunblind push button • Version: 11.07.2023 • Technical changes and errors excepted.

5. Display and operation at the device

5.1. Adjust room temperature

Depending on the setting of the "Display mode" parameter in the device application,

the KNX eTR 208 Light/Sunblind push button displays the current room

temperature value (or mixed value), the target value or the shift in relation to the basic

setpoint. The display can be dimmed and switched off via the bus so that no value is

displayed.

Option A: Display of actual temperature (room temperature)

The current room temperature is displayed. It is not possible to change the room

temperature manually using the +/- buttons.

Option B: Display of target temperature or basic setpoint shift

Depending on the setting, the current target value or the shift relative to the base

setpoint is displayed. The temperature can be changed by touching the +/- buttons.

Target value display (absolute value):

7 Display and operation at the device

KNX eTR 208 Light/Sunblind push button • Version: 11.07.2023 • Technical changes and errors excepted.

Display of the basic setpoint shift (change compared to the basic setpoint of the

control):

Option C: Display of actual temperature and target temperature/basic

setpoint shift

During normal operation, the current room temperature is displayed. By touching the

buttons, the display jumps to the target temperature or to the basic setpoint shift,

depending on the presetting. Changes with + or - are visible. The display returns to the

room temperature if no button is touched for 7 seconds.

Touch the + or - button briefly: The current target temperature (or the basic setpoint

shift) is displayed.

Tap +: Increase room temperature

(target temperature/basic setpoint shift is increased).

Tap -: Lower room temperature

(target temperature/basic setpoint shift is lowered).

Tap +:

8 Display and operation at the device

KNX eTR 208 Light/Sunblind push button • Version: 11.07.2023 • Technical changes and errors excepted.

General:

The step size for the change and the possible setting range are defined in the device

application (ETS). There you can also define whether the manually changed values are

retained after a mode change (e.g. Eco mode overnight) or reset to the stored values.

The button functions can be disabled in the ETS or locked due to operating mode with

priority 1.
