Optimus EDGE KNX Switch Sensor with Display & RTC 2-Gang / 4 Buttons (2-Row)

Part of the Optimus EDGE Automation switch series — a frameless, modular KNX switch sensor for wall installation. This model measures 80 x 120 mm and carries display row plus two rockers, giving 4 functions across 2 gangs.

The integrated display shows room temperature, setpoint and status, and the built-in Room Temperature Controller (RTC) lets the unit run heating or cooling on its own.

Each button can switch, dim, drive blinds, call scenes, send values or run logic. An RGB status LED gives feedback at a glance, and the icons are customisable. Available in white, silver, anthracite and black plastic, or stainless steel with a black matte base.

Compatibility

• Bus system: KNX twisted pair, to EN 50090 and ISO/IEC 14543-3.
• Configuration: ETS 5 or ETS 6. The manufacturer publishes the product database free of charge.
• Interoperable with KNX-certified devices from any manufacturer. ABB, Schneider, Siemens, Gira, Jung and Theben all sit on the same bus, so this unit works inside a mixed-brand installation.
• Bus supply: 21-30 V DC from a standard KNX power supply.
• Room temperature control: the setpoint and the measured value travel over the bus to KNX valve, fan-coil or underfloor heating actuators. No proprietary cabling.
• Not compatible with Zigbee, Z-Wave, Wi-Fi-only or Matter-only devices unless a KNX gateway is added.
