The EAE TD4 KNX Panel is a compact 4-inch room controller with capacitive IPS touch display. It combines lighting, shading, HVAC, and scene control with built-in environmental sensors — temperature, humidity, CO₂, and air quality (PM2.5, AQI, VOC) — in a single flush-mounted unit that fits standard 80 mm or 86 mm wiring boxes.

Unlike bus-only EAE sensors, the TD4 requires both KNX bus power and a 24 – 30 V DC auxiliary supply. Configuration is done entirely in ETS 5.7+ via the TD4x product file — no separate panel configurator software required.

Key Features — 4″ Capacitive Room Controller

Display and Interaction

• 4″ IPS display: 480 × 480 px colour capacitive touch screen.
• Proximity sensor: Wakes the display at 15 cm (standard) or 30 cm (enhanced).
• Touch vibration feedback: Haptic confirmation of commands.
• Colour LED strip: Status indication; red during KNX programming mode.
• Screen saver, password protection, and panel block for security.

Control and Monitoring

• Lighting: Switching, dimming, RGB / RGBW / RGBCW, and tunable white.
• Shading: Curtain and blind control with position feedback.
• Climate: 4-zone thermostat — room temperature, air conditioner, floor heating, ventilation.
• Air quality: PM2.5, AQI, CO₂, VOC display.
• Energy metering: Current, voltage, power, and energy display.
• Logic functions: AND, OR, XOR, gate forwarding, threshold, delay, staircase lighting.
• Scenes and timers: 8 scene groups, 8 time functions, weekly timer editable on screen.

Applications and KNX Integration

• Hotel guest rooms: Compact bedside or entrance control for lighting, HVAC, and scenes.
• Residential apartments: Single-room controller with air-quality feedback.
• Office meeting rooms: 4-zone thermostat and RGB lighting from one panel.
• Larger projects: For whole-building control with intercom and mobile app, step up to the EAE MIOLA 10″ KNX Touch Screen.
• Room actuation: Pair with EAE RCU Room Control Units or separate actuators for load switching.
• Auxiliary power: Supply 24 V DC from an EAE PS640 KNX Power Supply auxiliary output.

Choosing EAE Touch Panels

The TD4 is EAE's compact ETS-configured room panel — ideal where a 4″ display suffices and auxiliary power is available. For multi-room server-style control with SIP intercom, dual LAN, and mobile integration, choose the MIOLA 10″ platform.
