Enertex® ViTa KNX
Presence redefined. Invisible within the push button.
The Enertex® ViTa KNX presence detector combines state-of-the-art radar technology with an elegant, unobtrusive push-button design. Unlike conventional presence detectors, the ViTa push-button versions are not installed on the ceiling but replace a classic wall-mounted push button at standard operating height. The familiar push-button function is fully retained. Thanks to its discreet appearance, the ViTa KNX blends harmoniously into any interior design – entirely without the conspicuous lens typical of classic PIR detectors.
Radar detects even vital movements
The name ViTa stands for Vital Movement Detection Push Button. Its high detection performance is based on modern 60 GHz radar technology. The short wavelength enables reliable detection of even millimeter-scale movements. With three detection zones, the ViTa KNX provides easy-to-configure detection. For directional movements, it can identify the direction of motion and distinguish whether a person is approaching or moving away from the detector.
Detection of the push-button versions
Unlike conventional presence detectors, the ViTa KNX exhibits high sensitivity not only horizontally but also vertically – upwards and downwards relative to the installation position. This makes it particularly suitable for stairwells and multi-level areas, as people are reliably detected as soon as they enter the stairwell. As a pure motion detector, it impresses with an exceptionally wide detection angle of nearly 180° (horizontal and vertical). This makes the ViTa KNX ideal for use in door areas: the detector responds immediately when the door is opened and reliably switches on the light.
Movement is detected frontally at distances of up to 10 meters; laterally as well as upwards and downwards, the effective detection distance is up to 4 meters. The presence of a standing person is reliably detected up to approximately 6 meters, while a stationary person is detected up to 3 meters.
Flexible installation, familiar operation
Installation offers a high degree of flexibility. The ViTa KNX push-button versions can be installed at heights of approximately 1.1 m, 1.4 m, or higher or lower without impairing detection quality. As these detectors are wall-mounted, complex ceiling installation is completely eliminated, while they remain fully operable as standard wall push buttons.
- Rockers optionally usable as individual push-buttons
- Functions for switching, dimming, colored light control, blinds control, value generation, scene recall
- Compatible with standard flush-mounted boxes
More than presence: temperature, humidity and light
Beyond pure presence and motion detection, the ViTa KNX measures temperature, humidity, and brightness using integrated sensors. In the push-button versions, two additional inputs enable further applications, for example window contacts, external push buttons, or temperature sensors. In addition, a status LED can be controlled via KNX for indication purposes (light sensor function significantly impaired). An additional logic module provides further flexibility for system integration.
Flexible evaluation and secure KNX integration
- Alarm for motion detection with filter and time window function
- Three separately configurable channels for motion/presence detection
- Counter for incoming and outgoing movements (people counting in passage areas) as well as differential counting
- Supports up to eight logic functions
- Built-in bus coupler for power supply via the KNX bus (no additional power supply required)
- KNX Data Secure
- Option to fully deactivate the radar sensor
Enertex® ViTa KNX Präsenzmelder UNI
Variant 1181-01-UNI is supplied with a pure white single rocker. The rocker and support ring are compatible with numerous 55 mm frame systems from established manufacturers such as Gira, Busch-Jaeger, Merten and Berker. This allows the presence detector to blend seamlessly into many existing switch ranges without disrupting the overall design.
Order number: 1181-01-UNI
Enertex® ViTa KNX Präsenzmelder LS
Variant 1181-02-LS is designed for rockers and frames from the JUNG LS series. It can be fitted with a single or double rocker, each available with or without a viewing window (dome). For rockers and frames from the JUNG A series as well as frames from the Enertex “AluRa” series, the separate hardware variant 1181-02-AR is available.
Order number: 1181-02-LS
Enertex® ViTa KNX Präsenzmelder AR
The high-quality solid aluminum frames from the Enertex “AluRa” series harmonize perfectly with the sophisticated design of the Enertex ViTa KNX. The rocker switches used are from the JUNG A series. Alternatively, frames from the JUNG A series or inserts for the JUNG LS series can be used (separate order number for the LS series).
Order number: 1181-02-AR
Enertex® ViTa KNX Präsenzmelder DK
Variant 1181-DK is designed for surface mounting on the ceiling. Its compact housing, measuring Ø 45 × 21 mm, can be easily planned or retrofitted on almost any type of ceiling. Thanks to its seamless, entirely lens-free surface, the presence detector remains discreet and unobtrusive.
Motion is detected at distances of up to 6 m. Standing persons are reliably detected up to 4 m away and stationary persons up to 3 m away.
The ceiling variant has no push-button function and no multifunctional inputs.
