Rotary heat exchanger for heat recovery
Function
Decentralised supply and extract air units for room ventilation, isothermal units that compensate for the heat loss due to ventilation according to the technical data. 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 in energy efficient operating situations. If necessary, the air is heated by the heat exchanger before it is discharged towards the ceiling with a high propulsive force. The extract air first passes through 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. In case of a power failure, the outdoor air and exhaust air dampers are closed to ensure fire protection, 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, and the selected air outlet ensures good overall room ventilation.Once the air reaches the opposite wall, it moves downwards and eventually through the entire space. By the time the airflow reaches the occupied zone it has a very low velocity.

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.
