FCA 1 Fan Coil Actuator

FCA 1 is a fan coil actuator suitable for operation
on the KNX.
FCA 1 controls the fan coil with up to 3 fan stages. It also controls the heating and cooling valve, whereby 2-way and 3-way valves can be actuated. An additional relay allows the selective control of an electric heater bank or an electric cooler bank. 2-pipe systems and 4-pipe systems are supported.

FCA 1 has 2 free-floating inputs for window contacts and monitoring humidity. The window contact input can be reconfigured as a temperature sensor.

  • The operating state is displayed via 9 LEDs:
  • 3 LEDs (red) for displaying the fan stage
  • 1 red LED for displaying heating mode
  • 1 blue LED for displaying cooling mode
  • 1 red LED for displaying additional relay ON
  • 2 red LEDs for displaying input 1 and/or input 2 closed
  • 1 red LED for displaying manual mode
  • FCA1 has 2 keys for easier set-up. One key selects various fan stages
    The other key enables toggling between heating and cooling modes.
