JUNG 24 volt bus
The JUNG bus is the installation solution using 24 volt technology. The system only needs a few devices and has a low cable requirement. The JUNG bus system enables central control of fundamental building functions and can often be found in repeating building structures such as hotel rooms.
Elementary components of the electrical installation with the JUNG bus are the relay station for controlling lighting, blinds and shutters, and the dimming station for dimming and switching the lamps. For the operating controls, the system uses sensor modules, push-buttons and the key card holder.
Control of lighting, blinds and shutters
The relay station Universal 8-gang has eight floating outputs for controlling various functions, such as blinds including slat adjusting. These functions can be activated in concert, as the practical central function controls the operation of blinds and shutters as well as the lighting. A parallel switching of two relay stations or of a relay station with a dimming station to extend the functions is also possible.
The relay station is controlled using the 2-wire bus technology by the JUNG bus push-buttons or the sensor module. It is also possible to control every output of the relay station using a conventional push-button with the input side of the station for an individual contact for each channel.
Dimming and switching the lighting
The dimming station has four channels for dimming and switching the lighting, offering all the functions of a JUNG dimmer, including a memory function to remember the brightness value. When switching off the lighting, the dim-down function can be used. After the shut-off delay, it will continuously lower the lighting before switching it off completely. The dimming station can also be operated by integrators using the built-in button panel without any control units being connected, which can be helpful when commissioning. In general, it is possible to connect two dimming stations in parallel to extend the channels. If the shading is to be regulated as well, the dimming station can be connected in parallel with the relay station Universal.
Operating controls in the JUNG bus system
For convenient operation of the relay and dimming station, we offer three components: the sensor module, push-buttons and the key card holder.
Sensor module
The operating field of the sensor module is divided into 16 sensor points that can each be allocated a function. In addition, multiple functions can be combined into a scene. In this way you can control four different scenes. A light touch of the sensor operating area is enough to run the allocated function or scene. The flexible allocation offers numerous possibilities to configure the control module alongside the use of images, symbols or text to clearly indicate functions and show the current settings. For easier installation, the electrician can copy the configuration of the module onto other modules.
You have the option to customise the insert for push-buttons by graphically design all 16 sensor pads of the module. If you want to emphasise the scene control in the living room, this area is simply given a larger operating surface on its push-button. This makes it easier for you and your guests to notice the functions and makes the individual sensor areas stand out visually.
Push-button
Using the push-buttons, you can control lighting, blinds and shutters with the large operating controls. A press of the button initiates the desired function, which can also include scenes. Configuration is done by the electrician with key combinations on the device. For more flexibility, the extension module extends a 4-gang push-button, for example, into an 8-gang unit at low cost. The simple set-up allows the configuration of a push-button to be transferred to another device.
Key card holder
In hotel operations, the JUNG bus provides particular convenience for the guests as it is also possible to connect the key card holder to the Universal dimming station. When guests insert the key card, the room lighting switches on automatically as a central function. When the guests take out the card again, the lighting stays on for a minute and the dimming station can still be used. This is followed by a fade-out phase, in which the lighting is dimmed to minimum brightness within three minutes and then switched off.
