The ABB i-bus® KNX PEONIA thermostat panel is a premium flush-mounted (FM) room interface combining a 2/4/10-fold rocker line (order as 4-fold, 6-fold, or 10-fold — types U2, U3, U5) with an integrated room temperature controller (RTC), 3.5″ TFT display, and capacitive RTC touch button with vibration feedback.

Beyond HVAC setpoint control, rockers support switching, dimming, blind/shutter operation, value sending, step-type switching, light scenes, and fan functions. The display shows operating mode, room temperature, and optional environmental data (time, PM2.5, CO₂, humidity, VOC) where configured. A proximity sensor enables wake-up and energy-saving behaviour when the panel is not in use.

Key Features — Display, RTC, and Control

Room Temperature Control

• Constant room temperature controller for 2-pipe and 4-pipe fan-coil systems and conventional heating/cooling.
• Fan stage control: Manual or automatic fan-speed switching; base-load operation supported.
• Single / Master / Slave configuration for coordinated temperature control across larger zones.
• Integrated temperature sensor and bus coupler — one MDRC position for control and sensing.

Display and Rocker Interface

• 3.5″ TFT display: Operating mode, temperature, and dynamic animations for dimming, blinds, and scenes.
• 2/4/10-fold layouts: 4-fold (2 rockers), 6-fold (3 rockers), or 10-fold (5 rockers — up to 10 functions).
• Replaceable rockers without icons; programmable LED per rocker plus top/bottom ambient LED strips (seven colours).
• Capacitive RTC button with haptic vibration feedback for intuitive setpoint adjustment.

Applications and KNX Integration

• Hotel guest rooms: Combined RTC, lighting, and blind control from one PEONIA plate with proximity wake-up.
• Office perimeter zones: Fan-coil RTC with scene recall and dimming on adjacent rockers.
• Residential living areas: TFT status display and ambient LED feedback for premium interiors.
• ETS configuration: Import the official .knxprod application (Downloads), configure RTC parameters, Master/Slave groups, display pages, and LED colours.
