ABB I BUS KNX RM/S3.1 Room Master 2CDO110165R0011 ABB STOTZ

ABB I BUS  KNX RM/S3.1  Room Master 2CDO110165R0011 ABB STOTZ

The ABB I-BUS KNX RM/S 3.1 Room Master is a sophisticated, multi-functional touch sensor and control unit designed for intelligent building automation via the KNX standard. It serves as the primary user interface for occupants in a room, allowing intuitive control over lighting, shading, temperature, and ventilation, all from a single, elegant device.

It is part of ABB’s popular STOTZ-KONTAKT series, known for its reliability and high-quality design.

Key Features

• Multifunctional Control: Integrates control for lighting (on/off, dimming, scenes), blinds/shutters (up/down, stop, slat adjustment), and room temperature (setpoint adjustment, operating mode selection).

• Elegant Touch Interface: Features a sleek, glass-fronted design with a capacitive touch surface for modern and intuitive operation.

• Integrated Sensors:

  • Temperature Sensor: For precise room temperature monitoring.

  • Brightness Sensor: For constant light control (maintaining a constant illuminance level by adjusting artificial light based on daylight).

• 4 Programmable Buttons: Four physical buttons with integrated LED status indicators. These can be freely programmed for any function, such as scenes, individual switching commands, or panic functions.

• Clear Visual Feedback: The central ring and buttons feature RGB LEDs, providing clear status feedback (e.g., red for heating, blue for cooling, green for preset temperature, or custom colors for lighting scenes).

• Room Master Functionality: Acts as the central control point for a “room,” often linking together various KNX actuators and sensors for a cohesive user experience.

• Modern Design: Frameless design that fits perfectly with standard mounting boxes and ABB’s future linear and pure design frames.

Main Functions and Applications

1. Lighting Control:

   • On/Off switching and dimming (via touch ring rotation or swipe gestures).

   • Direct activation of predefined lighting scenes (e.g., “Reading”, “Relax”, “Off”).

   • Control of multiple lighting groups.

2. Shading Control:

   • Control of blinds, awnings, and shutters (Up, Down, Stop).

   • Adjustment of slat angles.

   • Activation of sun protection or weather scenarios (e.g., “All Blinds Up”).

3. Room Climate Control:

   • Display and adjustment of the current room temperature.

   • Setting the desired temperature setpoint.

   • Switching between operating modes (Comfort, Standby, Economy, Frost/Heat Protection).

   • Control of fan coils and ventilation units.

4. Ventilation Control:

   • Switching ventilation systems on/off or adjusting fan speeds.

5. Status Indication:

   • Visual confirmation of commands via the LED ring.

   • Alarm signaling (e.g., flashing red for a burglar alarm).

   • Indication of system status (e.g., “Away” mode active).
