The Gira Fan Coil Actuator (2163 00) is intended for KNX-based control of compatible fan-coil equipment in building HVAC applications. It allows the room automation system to issue configured control commands to the supported fan-coil functions, helping coordinate HVAC operation with the wider KNX installation. The precise number of outputs, supported fan stages, valve control options and electrical ratings must be confirmed from the manufacturer’s technical data for this article number. Correct application design is important because fan-coil equipment can use different motor, valve and control arrangements. Before procurement, check the wiring diagram, load and supply requirements, operating modes and ETS application, and have the installation commissioned by a qualified professional.
