Functional description
Each decentralised ventilation unit has its own controller. This controls all functions that are necessary for operation, e.g. providing the control signal for fans and actuators. Through configuration and special software and hardware extensions, the existing controller is converted into a master controller that is required at least once in the room. Additional inputs and interfaces allow for the connection of components that are required for room control. The master controller can be extended using the RTC interface with a timer or Modbus RTU, Modbus TCP, BACnet MS/TP or BACnet IP interface for connection to a central BMS provided by others.
Operating temperature | -20 – 60 °C |
Relative humidity | 5 – 95%, no condensation |

Storage temperature | -30 to 70 °C |
Power consumption (depending on equipment) | 14 W |
FSL-CONTROL III is described as stand-alone single room control equipment with a simple timer. Optional expansions, such as connection to the central BMS (provided by others) via Modbus or NACnet, humidity sensors, return flow temperature sensors, electromotive valve actuators or pressure-independent control valves are included in the product range, but must be replaced with the standard components in the following description. A room temperature signal is also required. Various room control panels and sensors are available for this purpose. The corresponding optional equipment can be found in the appendix of the following standard equipment for room-autonomous operation.
TROX control module FSL-CONTROL III (order code ... -C3-MA ...)
Single room controller for DIN rail assembly in the device or in a separate control casing. 42 digital or analogue inputs and outputs. A MicroSD card is integrated flash memory. The trend data is stored here and can be accessed via the RJ45 service socket or optionally via Ethernet. Equipped at the factory with a software package for master units specially developed for decentralised ventilation units. The software enables simple master-slave communication via Modbus RTU. Up to 10 slave devices can be connected to one master device. The software provides 3 operating modes (Off, Automatic and Manual), 3 operating modes (Present, Absent and Standby) and 4 operating mode overrides (Boost, Ward, Night Ventilation and Fan Forced Circuit).
Basic distinction between room temperature control by controlling heating and cooling valves or continuous bypass damper or supply air temperature control for isothermal ventilation. CO2- or VOC-guided air quality control. Year-round heat recovery use.
Integrated web server for simple configuration, commissioning and remote monitoring of the unit.
Filter monitoring
Configurable digital inputs (DI), e.g. for connection (by others) of PIR sensor, window contacts, holiday switching, etc. Alarm signals type A (switch-offs) and type B (notifications).
Real-Time-Clock (RTC / real-time clock) (order code ...-T/...)
Component of the Master Software Package. Enables a simple timer, 7 days with 10 switching points each. Automatic summer/winter time changeover. Temporal activation of night purge.
CO2sensor (order code .../C/...)
Sensor arranged in the extract air intake of the master unit for recording the indoor air quality and corresponding control of the fresh air flow rate. Measurement via an NDIR sensor, which works on an infrared basis and compensates for any contamination by its 2-beam measurement principle. Measuring range 0 – 2000 ppm.
VOC sensor (order code .../V/...)
Sensor arranged in the extract air intake of the master unit for recording the indoor air quality and corresponding control of the fresh air flow rate. Measurement via a micro metal oxide sensor with regular automatic calibration. Measuring range 0 – 2000 ppm CO2-equivalent.
Supply air temperature sensor (order code .../Z/...)
Supply air temperature sensor with NTC thermistor as sensing element, resistance 10 kΩ at 25 °C, measuring range 0 – 50 °C. Especially fast response time due to perforated measuring tip.
Outdoor air temperature sensor (order code .../A/...)
Outdoor air temperature sensor with NTC thermistor as sensing element, resistance 10 kΩ at 25 °C, measuring range -30 – 50 °C.

General information
Use only cables that are designed for the supply voltage for which they will be used. The length and cross section as well as any contact resistance may increase voltage losses. The power rating of each decentralised ventilation unit in accordance with the following table must also be considered.
The selection of cable types and the sizing of the cables must be carried out by the electrician laying the cables. This job must only be carried out by specialist electrical companies. For the sizing of the cables, the connecting cables are listed below.
