KNX F 40 push-button – functional diversity with large operating buttons

Great user-friendliness is what the KNX F 40 push-button stands for. Thanks to the large operating areas, the push-button is convenient to use while also offering control of multiple functions with just one switch.

Control smart homes with ease

Not only are the KNX F 40 push-button's square controls optimised for convenient handling, each button can also be synced with multiple functions simultaneously in the KNX system to create a pre-programmed scene.

A wide selection of materials and colours

Either matching or contrasting with interior design styles, the KNX F 40 push-button is available in various high-quality materials and in different colours. From aluminium, stainless steel, chrome and gold-coloured to brass, there is something for every interior.

Choosing the right design

The F 40 push-button is available in the LS, A, AS and CD switch series in a wide range of shapes, materials, colours and finishes. It blends harmoniously into any design concept - from classic to modern.
LS range
Characterised by a narrow frame that gives the switch a large operating surface, the LS range fits superbly into any ambience.
A range
With high-quality plastic or glass frames in various colours, the A range suits a light and youthful atmosphere. 

Manual building control

The F 40 push-button can be fitted both through the KNX bus lines or wirelessly with KNX Radio Frequency (RF), giving you the flexibility to place it in the most convenient location. It is also able to be combined with other push-buttons, room thermostats or sockets in a 2-gang or more frame.

The JUNG KNX push-button F 40 has an integrated temperature sensor and thus contributes to efficient room temperature control. It can also be securely encrypted with KNX Secure.
KNX RF F 40 push-button
The wireless version with KNX RF bypasses structural conditions where no twisted-pair cable can be laid or is not wanted. The battery-operated inserts function as wall transmitters, allowing KNX RF push-buttons to be stuck on anywhere.

F 40 KNX compact room controller

With the KNX compact room controller, lighting, temperature, and blinds can be centrally controlled.
The device has large operating areas that can be imprinted with symbols individually using the JUNG GRAPHICTOOL. The illuminated digital display clearly shows parameters of the room and the current time. In addition, it is possible to expand its functions by adding a universal push-button sensor extension module to include a 1-gang to 4-gang push-button. With the help of the integrated sensor, the compact room controller reliably measures the room temperature. 
 



The advantages at a glance:
  • uniform design that matches with the KNX F 40 push-button
  • demand-based room temperature control through integrated temperature sensor
  • independent control of a second room with an external temperature sensor
  • light, shade and temperature control in one device
  • good readability from every angle because of its backlit LC display
  • cost reduction by up to 30 percent due to individual control of two rooms with a room controller with an extension module
  • individual labelling with the JUNG GRAPHICTOOL

For easy recognition

The multitude of functions allocated to the F 40 push-button can be easily identified with the JUNG GRAPHICTOOL via either high-quality laser engraving or colour printing - making operation easy even for new users. 
Laser
Refine the surfaces of JUNG as desired with high-quality laser engraving.
Digital printing
Designed in abrasion-resistant digital printing, JUNG products are unmistakable.

Dual operation modes

The F 40 can be configured to be operated either with a rocker or push-button function. As a rocker, its operation is divided into two operating pressure points to adjust a single basic function. As a push-button, each operating surface can be configured to manage two individual functions. 

Smart technology for everyone

Storing information on different scenes, supporting cost-efficient extensions of the electrical installation and embodying an installation-friendly concept: the F 40 push-button impresses installers on the site just as much as the owner in the finished home.
Connection of the extension module
Your specialist connects the flat push-button extension module directly to the main module for flexible extension of its functions. With the help of a special supporting metal frame, it is mounted on a 2-gang frame. The advantage for retrofitting is that a separate flush-mounted box is not necessary. 
Covering on construction site
Thanks to the temporary cover, the push-button module is safe in the construction site and can be installed even before the switch design range is selected and fitted on. 
Quick button mounting
Push-button covers come together with a mounting aid that makes its mounting quick. In addition, each cover can be individually replaced at any time with a lasered or printed version for example. 
Temperature sensor
With its temperature sensor, the F 40 is able to measure the temperature in the room and transmit the parameters to the room temperature controller or room controller.
Lighting scene memory
You can store up to 8 different light scenes in its integrated light scene memory. Every scene can be allocated to eight groups.
