Frequently Asked Questions - A1751 JUNG

How do I pair my smartphone with the JUNG A1751 cover?

Press the ✝ button (4b) for more than 4 seconds until the blue LED flashes slowly. Then start the Clever Config app on your smartphone and search for devices. Select the Jung Timer BT cover to complete coupling.

What does the blue flashing LED mean?

Flashing blue indicates Bluetooth coupling mode is active. If it flashes three times repeatedly, the time is not set and will be updated when you connect with the app.

How can I reset the device to factory settings?

Within the first 2 minutes after switching on mains voltage, press and hold buttons (3a) and (3b) for over 20 seconds until the red status LED flashes quickly. Release and press briefly again within 10 seconds. The device resets and the blue LED flashes three times.

How do I save the blind/shutter running time?

Move the blind to the upper end position. Then press (3b) for longer than 1 second to start moving down. Press and hold (3a) and (3b) simultaneously; the blind stops but continues after 4 seconds. When it reaches the lower end position, release and press (3b) within 4 seconds to save.

What is the ventilation position and how do I set it?

The ventilation position is a partial opening of the blind for air flow. From the upper end position, press (3b) for longer than 1 second, then press and hold (3a) and (3b) until the desired position is reached. Release and press (3a) within 4 seconds to save.

How can I activate night mode?

Press and hold buttons (4a) and (4b) for more than 4 seconds. The function LED turns red for 3 seconds to confirm activation. In night mode, LEDs light only for 5 seconds after a button press.

How do I deactivate automatic operation?

Press the ✝ button (4b) briefly. The function LED turns orange, indicating automatic operation is deactivated. Saved switching times will not be executed.

Can I control the device if it has a different insert?

If the cover was previously paired with another insert, the status LED flashes red three times repeatedly. To use it with the new insert, either place the cover back onto the original insert or press (3a) and (3b) for more than 4 seconds.

How many switching times can I program?

You can program up to 40 individual switching times using the Bluetooth app. Each time can include positions for blind/shutter, slat, or dimming values.

What should I do if the blue LED flashes three times repeatedly?

This indicates the time is not set. Connect with the Clever Config app, which will automatically update the date and time via your smartphone. After that, the blue LED should stop flashing.

4 Commissioning

Install app on a mobile end device

Requirement for operation via app is a mobile end device with Bluetooth interface, running the Android operating system or iOS.

■ Download and install the Bluetooth app Google Play Store (Android).

Clever Config from the iTunes App Store (iOS) or

Couple mobile end devices via Bluetooth

Precondition: The insert must be connected and switched off. The cover is placed on the insert and the mobile end device is close to the cover.

■ Activate coupling mode: Press the ✝ button (4b) for more than 4 seconds. The blue LED flashes slowly. The coupling mode is active for one minute.

■ Start the Clever Config app and search for the device to be coupled. The Jung Timer BT cover is displayed in the app.

■ Perform coupling. The coupling mode is automatically exited after successful coupling. The blue LED lights up to confirm an active connection.

A maximum of 8 mobile end devices can be coupled with a cover. When coupling the 9th device, the least used device will be deleted.

To be able to perform position movements of the blind/shutter on a Venetian blind insert, a reference movement is performed in the upper end position after the programming. This reference movement should not be stopped.

5 Operation of Venetian blind and shutters

All settings and operations are also possible via Bluetooth app.

Moving the blind/shutter

- Press button (3a) or (3b) for longer than one second. The blind/shutter moves in the desired direction to the end position or stops when the button is pressed again.

If a ventilation position has been saved, the blind stops in the ventilation position when moving down (see Saving the ventilation position).

Adjusting the slats

■ Press the button (3a) or (3b) for less than one second.

Saving blind/shutter running time

To perform positioning movements, the blind/shutter running time has to be saved beforehand.

To save blind/shutter running time, the Venetian blind must be moved to the upper end position and the status LED (6) switch off automatically.

■ From the top end position, press the button (3b) for longer than second. The blind/shutter moves in the lower end position direction.

■ Press and hold down the button (3a) and (3b).
The blind/shutter remains stopped, but continues to move after 4 seconds.
■ As soon as the blind/shutter has reached the lower end position, release the buttons and press button (3b) within the next 4 seconds.
The running time is saved. The blind/shutter moves back to the upper end position.

Saving the ventilation position

To save the ventilation position, the Venetian blind must be moved to the upper end position and the status LED (6) switch off automatically.

■ From the top end position, press the button (3b) for longer than second.

The blind/shutter moves in the lower end position direction.

■ Press and hold down the button (3a) and (3b).

The blind/shutter remains stopped, but continues to move after 4 seconds.

■ As soon as the desired ventilation position has been reached, release the buttons and press the button (3a) within the next 4 seconds.

The ventilation position is saved. The blind/shutter moves back to the upper end position.

i If the ventilation position is saved again, the old value is overwritten.

6 Operation of lighting

All settings and operations are also possible via Bluetooth app.

Switching the light

■ Press button (3a) or (3b) for less than 0.4 seconds.

With a dimming insert, the light switches to the brightness that was last set or a saved brightness.

Switch light on with minimum brightness

■ Press the button (3b) for longer than 0.4 seconds.

Adjusting the brightness

■ Press button (3a) or (3b) for longer than 0.4 seconds.

Save switch-on brightness

■ Adjusting the brightness

■ Press the buttons (3a) and (3b) for longer than 4 seconds.

Switch-on brightness is saved. For confirmation, the light is switched off briefly and switched on again.

Delete switch-on brightness

■ Press button (3) briefly: Light switches on at the saved switch-on brightness.

■ Press the buttons (3a) and (3b) for longer than 4 seconds.

The switch-on brightness has been deleted.

Switching on takes place at the last brightness value set. For confirmation, the light is switched off briefly and switched on again.

7 Activate functions

Activating / deactivating automatic operation

■ Press button ✝ (4b) briefly.

If automatic operation is deactivated, the function LED (5) turns orange. Saved travelling times are not executed.

Activating / deactivating the disabling function

The disabling function disables extension operation and operation via the app and deactivates automatic operation. Manual operation using the buttons (3a) and (3b) continues to be possible.

With Venetian blinds, extension operation in the "UP" direction (wind alarm) continuous to be possible.

■ Press the button (4a) for longer than 4 seconds.

The disabling function is activated or deactivated.

The function LED (5) turns red if the disabling function is active.

Activating / deactivating night mode

In night mode, the status and function LEDs are not permanently lit, but only for 5 seconds after a button is pressed.

■ Press the buttons (4a) and (4b) for longer than 4 seconds.

Night mode is activated: The function LED turns red for 3 seconds.

Night mode is deactivated: The function LED turns green for 3 seconds.

Resetting the device to the factory setting

■ Press the (3a) and (3b) buttons during the first 2 minutes after switching on the mains voltage for longer than 20 seconds until the red status LED flashes quickly.

■ Release buttons (3a) and (3b) and press briefly once again within 10 seconds.

The red status LED flashes more slowly for approx. 5 seconds.

The device is reset to default setting. The blue function LED flashes three times to indicate that the time is not set.

On a Venetian blind insert, a reference run to the upper end position is performed.

i After resetting the device to the default setting, it has to be removed from the app. On iOS equipment, the device also has to be removed from the list of paired Bluetooth devices (Settings/Bluetooth). Otherwise, re-pairing will not be possible.
