FBLb - Airflow controller

FBLb is used with a damper, a damper actuator and a measuring flange for balancing supply and extract air or for maintaining a constant airflow. The controller is also used for flow measurement. The integrated air flow sensor is factory calibrated. FBLb is included in airflow control unit DCV-BLb and in flow measurement unit DCV-MFb, see the product category Smart Dampers. The controller is connected to 24 VAC and a communication loop (CAN)
via a common 4-wire.


  • Used in combination with a damper, a damper actuator and a measuring flange to either measure, keep constant, sum or balance air flows in a way that allows great flexibility when designing room climate solutions.
  • Can be part of a flow zone that includes up to 100 active supply air devices or other control units.
  • Can add a positive or negative airflow offset.
  • By making a function selection, the device can act as a slave in relation to another flow control in the zone.
  • The controller is programmable and its parameters can be read or set locally via handset or centrally over the network.
  • Connects via Node-ID to a local area network (CAN) for stable communication between cooperating units.
  • Equipped with Bluetooth® for communication via mobile application LINDINSIDE.
User interface
  • Login localy directly to the controller via a smart phone with the LINDINSIDE app.
  • TCP/IP networking over Gateway NCE and Lindinvents central unit and system software LINDINSPECT.
  • Other external parent system via Gateway NCE and ModbusRTU or ModbusTCP.
  • Fixed user panel FLOCHECK P, which can be wired directly to the controller.
