Functional description
Decentralised supply and extract air units for room ventilation and for dissipating heat loads. An EC centrifugal fan takes in the outdoor air which then flows through the motorised shut-off damper and the outdoor air filter. The outdoor air then flows through the rotary heat recovery unit, which can be switched off if it is more energy efficient. If necessary, the air is heated by the electric air heater before it is discharged through the supply air grille towards the ceiling (Coanda effect) with a high propulsive force, yet without creating a draught.
The extract air first passes the extract air filter, then flows through the heat recovery unit, the extract air fan and the motorised shut-off damper before it is discharged to the outside as exhaust air. If the indoor air quality is sufficient, FSL-CONTROL III closes the outdoor air dampers and changes to secondary air operation, which is more energy efficient in any case. The control system compares the room air quality setpoint value to the actual value measured by the CO2 sensor and switches automatically between outdoor air and secondary air operation.
If the power fails, the outdoor air and exhaust air dampers are closed to ensure fire protection and frost protection and to avoid draughts. This is ensured by a capacitor in each actuator.
The supply air is discharged near the ceiling with a medium velocity. Rather than flowing immediately downwards, the air moves along the ceiling (Coanda effect) and reaches every corner; this ensures complete ventilation even of large rooms. Once the air reaches the opposite wall, it moves downwards and eventually through the entire space. The airflow reaching the occupied zone has a very low velocity and rises on heat sources, for example on people and devices. This is called natural convection. As a result, the air is exchanged primarily in these areas. The stale air is extracted under the ceiling and led to the outside.

FSL-CONTROL III controller
Including control system FSL-CONTROL III, as described below:
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. You will find related text modules below.
