Home » Room control designed for hospitality: Zennio’s CX family




A hotel room is more than a place to stay. It is an experience shaped by light, temperature, atmosphere and the small details that make guests feel comfortable. Zennio’s CX family brings these elements together through a single, elegant interface designed for modern hospitality spaces.
The range includes the CX33, with a 3.3” display, the CX40, with a 4” display, and the CX50, with a 5” display. Each model offers a different scale while maintaining a consistent and intuitive experience throughout the hotel.
Lighting, blinds, climate, audio, scenes and timers can be brought together in one touch controller. The CX33 and CX40 support up to 54 controls, while the CX50 supports up to 96. Functions can be arranged across customisable pages, allowing the interface to adapt to the hotel’s needs and the way guests use each room.
The experience is fully customisable, from the functions and navigation to the appearance of the interface. Light and dark modes, colour icons and user-defined designs allow the screen to become a natural part of the room rather than a purely technical element. A screensaver can display the date and time or a personalised image, adding a more personal touch.
Climate control is integrated across the family, with temperature and humidity. All three models are powered through the KNX bus, feature four inputs and include KNX Secure.
Design is central to the experience. With their full-glass surfaces and reduced frames, the panels are designed to integrate into the interior while retaining a distinctive presence. The CX50 can be installed horizontally or vertically, and the family is available in Anthracite, Silver, Mocha, Champagne and White finishes.
By bringing comfort, atmosphere and control together in a single touchpoint, the CX family gives hospitality projects a more refined way to welcome technology into the guest room. Intuitive to use, effortless to experience and carefully considered down to the last detail.
