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.

Optional equipment to increase the comfort of the FSL-CONTROL III:



TROX room control panels for FSL-CONTROL III



At least one room temperature signal is required per room. There are several variants of TROX room control panels available, optionally with or without selector switch. Additionally, we offer a room temperature sensor RTF without control elements. Alternative on-site room control panels must be connected via bus communication.





 



Digital room control panels for surface mounting:



For operation and adjustment of the ventilation units.







 



Control panels with selector switch for surface mounting:



Control panel with selector switch, type Thermokon, for surface mounting:







 



Control panels without selector switch for surface mounting:

Version as SLAVE DEVICE



Identical to the MASTER DEVICE, as described above, but with the following deviations:



  • No room air quality measurement in the unit
  • No connection option for room control panels
  • No outdoor temperature detection in the outdoor air
  • No connection to on-site bus communication possible
  • Pre-assembled self-sufficient control system for decentralised façade ventilation units in SLAVE construction


Commissioning of the decentralised ventilation units

Commissioning/parameterisation of the decentralised ventilation units without integration into an on-site MCE/BACS



  • Visual inspection of the device connections on site for compliance with the respective installation specifications from the installation and configuration instructions: air connections, heating/cooling connection, electrical connections, integration into the installed outer casing, connections of external components
  • Checking and, if necessary, adapting the project parameters pre-set in the factory with regard to customer-specific adaptations
  • Functional test of the individual components (control elements, fans, valves, dampers, sensors)
  • Checking the project-specific control functions including any special functions such as volt-free switch contacts
  • Documentation of the device settings and service work in a service report. The service report must be signed by your company or representative as the client.
  • Invoicing is done as a flat rate, derived from the number of units and distance.

Installation and commissioning


  • Installation on the floor in front of the outside wall
  • Level adjustment using the 4 levelling feet (+40 mm)
  • 4 side fixing brackets (supplied loose) for screwing to the building structure, alternatively 2 fixing points below the heat exchanger can be used
  • The outdoor air intake or exhaust air discharge takes place via 2 façade openings. The façade openings must be professionally provided by the customer and ideally have a slope to the outside
  • Free area of ventilation openings: 0.05 m² for each outdoor air opening and exhaust air opening, and 0.16 m² for each supply air opening and extract air opening
  • Weather protection for the outdoor air and exhaust air openings to be provided by others
  • Installation and connections to be performed by others. Fixing, connecting and sealing material not included
  • Water supply and return connections are on the right-hand side of the unit, as seen from the room
  • The customer must ensure that the unit can be drained and vented.
  • The electrical connection is on the right-hand side of the unit, as seen from the room
  • We recommend using flexible hoses to connect the unit to the pipework so that the heat exchanger can be easily removed for cleaning.
  • The under sill trim provided by others must not obstruct maintenance access at the front of the unit or installation and removal of the unit.
