FSL-CONTROL III is described as a stand-alone single room control system with a simple timer. Optional expansions, such as integration into an on-site MCE/BACS via Modbus TCP, Modbus RTU, BACnet MS/TP or BACnet IP, humidity sensors, return temperature sensors, electromotive valve actuators or pressure-independent control valves, are included in the delivery programme, but must be exchanged for the standard components in the following description. A room temperature signal is also required. Various room control panels and sensors are available to provide this signal. Suitable optional equipment can be found after the following standard equipment for stand-alone operation. - please refer to: Optional control accessories. We recommend commissioning by TROX.

Funktionsbeschreibung Dezentrale Zu- und Abluftgeräte be- und entlüften den Raum und decken die Kühl- und Heizlast gemäß den technischen Daten ab. Die Außenluft wird von einem EC‑Radialventilator angesaugt und strömt durch die motorisierte Absperrklappe sowie durch den Außenluftfilter. Danach strömt die Außenluft durch den Rotationswärmerückgewinner, der in energetisch sinnvollen Betriebssituationen abgeschaltet werden kann. Bevor die Zuluft quellluftartig in den Raum strömt, wird sie bei Bedarf im Wärmeübertrager noch geheizt bzw. gekühlt (optional bei 4- Leiter-Geräten). Die Abluft strömt durch den Abluftfilter, bevor sie durch den Wärmerückgewinner, den Abluftventilator und die motorisierte Absperrklappe als Fortluft ins Freie gefördert wird. Bei ausreichend guter Raumluftqualität schaltet die FSL‑CONTROL III Regelung durch Schließen der Außenluftklappen in den energetisch sinnvollen Sekundärluftbetrieb. Die Regelung vergleicht dabei die Sollwerte der Raumluftqualität mit den am CO2‑Sensor gemessenen Istwerten und schaltet automatisch zwischen Außenluft- und Sekundärluftbetrieb um. Zum Brandschutz, Frostschutz und zur Vermeidung von Zugluft werden bei Stromausfall die Außenluft- und Fortluftklappe zugefahren. Hierzu besitzen die Stellantriebe einen Energiespeicher. Die Zuluft strömt mit mittlerer Geschwindigkeit von 1,0 – 1,5 m/s fassadennah in den Raum. Durch die Induktionswirkung werden die Geschwindigkeiten bereits kurz nach dem Lufteintritt in den Raum abgebaut. Dadurch breitet sich die Zuluft im Kühlfall über die gesamte Bodenfläche quellluftartig aus. An Wärmequellen wie Menschen und Geräten bildet sich durch natürliche Konvektion eine Auftriebsströmung, so dass primär in diesen Bereichen die Luft ausgetauscht wird.
