Precise Climate Management with ABB FCC/S1.1.2.1 Fan Coil Controller
The ABB FCC/S1.1.2.1 (2CDG110211R0011) is a high-performance device engineered to bridge the gap between HVAC systems and KNX automation. Primarily, it is tailored for 2-pipe or 4-pipe fan coil systems, ensuring that heating and cooling are delivered with maximum precision.
Key Features and Functional Benefits:
  • Versatile Fan Control: The controller supports 3-speed fans through integrated relays. Furthermore, it includes programmable dwell times and start-up characteristics. As a result, fan operation becomes smoother, which significantly increases the lifespan of the hardware.
  • Analog Valve Integration: In addition to fan speed management, the device features two analog outputs (0-10 V). Specifically, these outputs allow for the proportional control of valves. Therefore, the system can maintain a much more stable room temperature compared to traditional on/off controllers.
  • Integrated Input Flexibility: Moreover, the FCC/S1.1.2.1 includes four inputs that can be used for room temperature sensors or window contacts. Consequently, the controller can automatically switch to “Economy Mode” when a window is opened, effectively preventing energy waste.
  • Comprehensive Safety Functions: Additionally, the device offers built-in protection against condensation and frost. Because of these automated safety features, the HVAC infrastructure is protected from potential water damage or freezing during extreme weather conditions.
  • Seamless KNX Commissioning: Finally, all parameters are easily configured via the ETS software. Moreover, the device supports the ABB i-bus® Tool, which simplifies the diagnosis and testing process during the installation phase.
Technical Specifications Summary:
  • Mounting: DIN-rail (MDRC), 6 modular units width.
  • Outputs: 3 fan speed relays and 2 analog 0-10 V outputs.
  • Inputs: 4 binary/analog inputs for sensors or dry contacts.
  • Application: Perfect for hotel rooms, offices, and luxury apartments using Fan Coil Units (FCU).
