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.
TROX control module FSL-CONTROL III (order code ...-C3-MA ...):
SEH Single room exhaust air
SRO Single room fresh air
SRS Single room supply air
SET Single room extract air
SEC Single room secondary air
1 Fresh air temperature sensor (optional)
2 Shut-off damper with actuator (exhaust air and fresh air)

4 EC fan (supply air and extract air)
5 Recuperator
6 Sound attenuator
7 Heating coil
8 Cooling coil (optional)
9 Supply air temperature sensor (optional)
10 Bypass damper with actuator (constant)
11 CO2 sensor (optional)
12 Extract air filter ISO coarse 55 %
Decentralised supply and extract air units for room ventilation and for dissipating cooling loads and heat loads. An EC centrifugal fan takes in the fresh air which then flows through the motorised shut-off damper and the fresh air filter. The fresh air then flows through the cross counter flow heat recovery unit that can be switched off to protect the unit and if it is more energy efficient. If necessary, the air is heated or cooled by the heat exchanger before it is discharged to the room as a displacement flow (for 4-pipe systems, this is optional). The extract air first passes through the outdoor 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 room 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 setpoint values of the indoor air quality with the actual values measured with the CO2 sensor and switches automatically between fresh air and secondary air operation. If the power fails, the fresh 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 external wall and with a medium velocity between 1.0 and 1.5 m/s. Due to the induction effect, the supply air velocity is rapidly reduced so that, in cooling mode, the supply air displaces the room air over the entire floor area. The convection from people and other heat sources causes the fresh air from the pool to rise and create comfortable conditions in the occupied zone.
