Product Description Z35 v3 3.5” Touch Display

The Zennio Z35 v3 is available in four elegant color variants:

• ZVIZ35V3W – White (RAL 9016)
• ZVIZ35V3S – Silver (RAL 9006)
• ZVIZ35V3A – Anthracite (RAL 9004)
• ZVIZ35V3C – Champagne (RAL 1035)

The Zennio Z35 v3 is a modern capacitive touch panel with a clear 3.5” color display (320x240 pixels), designed for advanced KNX-based home and building automation. With built-in sensors and flexible functions, the panel is ideal for controlling multiple features within a KNX system.

The panel includes integrated sensors for temperature, humidity, brightness and proximity. Thanks to the proximity sensor, the menu activates automatically when a user approaches. A screensaver with time, date, and/or temperature appears during inactivity.

The Z35 v3 supports KNX Secure communication for increased protection. It also features 4 analog/digital inputs for potential-free switches, motion sensors, or temperature probes.
