Interface for integration into an on-site MCE/BACS:


Modbus TCP interface including web server (order code .../MT/...)

To increase convenience, we recommend integration into an on-site MCE/BACS or visualisation with X-TAIRMINAL. FSL-CONTROL III can be integrated into an on-site MCE/BACS via the Modbus TCP protocol. Additionally including web server for simplified configuration, commissioning and remote monitoring of the unit. The MCE/BACS is not included in the supply package from TROX GmbH, only the interfaces listed above are available here.

  • Modbus TCP interface (Ethernet)

BACnet IP interface including web server (order code .../BI/...):

To increase convenience, we recommend integration into an on-site MCE/BACS. FSL-CONTROL III offers the option of being integrated into an on-site MCE/BACS via the BACnet IP protocol. Additionally including web server for simplified configuration, commissioning and remote monitoring of the unit. The MCE/BACS is not included in the supply package from TROX GmbH, only the interfaces listed above are available here.

  • BACnet IP interface (Ethernet)

Modbus RTU (order code .../MR/...)

To increase convenience, we recommend integration into an on-site MCE/BACS. FSL-CONTROL III offers the option of being integrated into an on-site MCE/BACS via Modbus RTU. The MCE/BACS is not included in the supply package from TROX GmbH, only the interfaces listed above are available here.

  • Modbus RTU interface (RS485)

BACnet MS/TP (order code .../BM/...)

To increase convenience, we recommend integration into an on-site MCE/BACS. FSL-CONTROL III offers the option of being integrated into an on-site MCE/BACS via BACnet MS/TP. The MCE/BACS is not included in the supply package from TROX GmbH, only the interfaces listed above are available here.

  • BACnet MS/TP interface (RS485)

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.

  • 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
  • Function test of the communication to the MCE/BACS in cooperation with the controls provider:
    • Checking that the on-site settings comply with the specifications in the installation and configuration instructions
    • Input test of the data points sent on site
    • Output test of the output data points
    • Trial operation of the operating states that can be switched by the MCE/BACS
  • 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.


 



Instruction in operation and maintenance



  • One-time instruction for the operation of the decentralised ventilation units consisting of:

    • Description of the equipment functions on the unit that has already been put into operation
    • Description of the room control panel and the room conditions that can be influenced by it
    • Description of the maintenance work
  • Invoicing is done on a flat-rate basis. The instruction is carried out by the responsible sales representative
