Frequently Asked Questions - BTCA518 JUNG

How do I install the BTCA518 thermostat?

Installation must be carried out by a qualified electrician. Connect the KNX bus wires to the supplied connector (red to +, black to -). Mount the thermostat into a flush-mounted box (Ø60mm) using the frame. After powering the bus, the device will start up automatically.

What is the operating voltage of the BTCA518?

It is powered by the KNX bus with a safety extra-low voltage (SELV) of 30V DC. No separate power supply is required.

Can I use the BTCA518 for both heating and cooling?

Yes, the thermostat supports both heating and cooling modes. You can switch between modes via the touch buttons or configure it through the KNX system.

How do I adjust the temperature setpoint?

Press the up/down touch buttons to increase or decrease the setpoint. The current setpoint will be displayed on the LCD. Adjustments are sent to the bus.

Does the BTCA518 have a presence sensor?

An optional presence sensor can be connected via the KNX bus. The thermostat can then switch between comfort and standby modes based on occupancy.

How do I reset the device to factory settings?

Press and hold the menu button (if available) for 5 seconds or follow the procedure in the user manual. Alternatively, a bus voltage interruption may reset certain parameters.

What does the display show?

The LCD shows the current room temperature, setpoint temperature, operating mode (e.g., comfort, standby, frost protection), and status icons for heating/cooling.

Can I control the BTCA518 via a smartphone app?

The BTCA518 is a KNX device and can be controlled via any KNX-compatible app (e.g., JUNG Smart Control) when connected to a KNX IP interface.

What is the accuracy of the temperature measurement?

The built-in sensor has an accuracy of ±0.5°C within the range of 0°C to 45°C.

How do I clean the thermostat?

Use a soft, dry cloth to wipe the surface. Do not use water, solvents, or abrasive cleaners, as they may damage the device.

USER MANUAL BTCA518 JUNG

Operating instructions

Description of device

The JUNG Bluetooth Connect BTC... consists of an operating cover and a flush-mounted power supply. The audio source (e.g. smartphone or MP3 player) is connected and the device is operated via the operating cover. The device is operated and set up via 8 sensor buttons.

The connections for mains voltage, loudspeakers and audio output are available on the power supply unit. The Bluetooth Connect can be operated with one or two loudspeaker modules LSM....

The music signal is transmitted via Bluetooth, amplified internally and output to loudspeakers or an external amplifier. The tracks and volume can be changed via sensor buttons. Up to 6 audio sources can be taught in, from which one audio source can be connected actively with the Bluetooth Connect.

Safety instructions

Electrical equipment must only be installed and assembled by qualified electricians. Failure to comply with these instructions may result in damage to the device, fire or other hazards. This product is only intended for use in dry rooms.

These instructions are an integral part of the product and must remain with the end customer.

Operation

The lower half of the cover is used for operation. All operations are made via 8 sensor buttons. In standby mode the buttons are hidden and are displayed each time you touch the lower area.

Switching on / Switching off

The Bluetooth Connect is switched on and off here (standby).

Note: After switching on, the Bluetooth Connect connects automatically to the last audio source if it can be reached. If the source is not available, e.g. because it is not within range, the next audio source is connected. The Bluetooth Connect attempts to reach the taught-in audio sources in the sequence they were taught in.

While searching for the connection, the button illumination dims brighter and darker. The playback starts automatically depending on the device type / device software.

Adjusting the volume

The volume is adjusted using the buttons. The Bluetooth Connect always starts with the volume that was last adjusted.

Teaching in the audio source

With a press of a button, the Bluetooth Connect switches to the learn mode and is then visible for a maximum of 30 seconds for audio players with an integrated Bluetooth interface (e.g. smartphone or MP3 player). A connection can now be established via such a device and it can be taught in on the Bluetooth Connect.

Note: During the 30 seconds, the buttons will flash until the connection has been established.

In some operating systems, a device that has previously been taught-in can only be taught-in again if the existing connection was deleted in this device.

Selecting the audio source

With a long press of a button (> 2 s) the connection to the next taught-in and accessible audio source is established. Afterwards, the playback is started. The search is indicated by dimming the button illumination brighter and darker. This procedure can last up to 40 seconds depending on the number of the taught-in devices.

Selecting a track

The last/next track can be selected by a brief press of a button. The track sequence corresponds to the order of the audio source. The sequence can normally be defined there according to albums, artists, genre or playlists.

Pause

With a press of a button, the playback of the connected audio source is interrupted.

Deleting connections

With a long press of a button (> 10 s), all previously taught-in audio sources are deleted from the Bluetooth Connect.

Installation

The Bluetooth Connect BTC... has been designed for installation in device boxes DIN EN 49073.

The connections for mains voltage, loudspeakers and the audio output are located on the flush-mounted power supply unit. The operating cover together with the frame are mounted onto the power supply unit.

Netzanschluss

The Bluetooth Connect requires a permanent mains connection. A loopthrough via the connecting terminals is not permitted.

Before carrying out work on the device, disengage all the corresponding circuit breakers. Cover up live parts in the working environment. Within the device box, all the cables carrying low voltages must have an insulating hose in order to guarantee protective separation.

Connecting an extension unit

The extension unit connection (1) is used to switch the Bluetooth Connect on/off via switches, e.g. together with the light. The extension unit input may only be operated on the same phase.

Before carrying out work on the device, disengage all the corresponding circuit breakers. Cover up live parts in the working environment. Within the device box, all the cables carrying low voltages must have an insulating hose in order to guarantee protective separation.

Connecting a loudspeaker

The device is intended for operation with one or two loudspeaker modules LSM... The connection cable can be up to 5 m long.

In stereo mode, both outputs (L+R) are used. The device detects autonomously if only one loudspeaker is used and then changes its operating mode to mono.

The connection of several loudspeakers per output is not permitted.

Loudspeakers of other manufacturers may only be used if the technical data is identical with the JUNG LSM....

Please observe the polarity.

Mono/Stereo change-over

If two loudspeakers are to be operated in mono, e.g. in separate rooms, it is possible to change over by pressing both buttons simultaneously for 10 seconds. The new mode is indicated by tones. One tone corresponds to the mono mode, and two tones correspond to the stereo mode.

Line-out (AUX)

The Line-out (AUX) is used for connecting to an external amplifier or to the JUNG Smart Radio RAD....

Installing the power supply unit

After connecting all cables, the power supply unit must be mounted in the device box in the correct position.

Installing the operating cover

After installing the power supply unit in the device box, the cover incl. the frame is mounted onto the power supply unit.
