The controller balances supply and extract air or controls airflow at a constant rate. FBLb can also be used only for flow measurement. The integrated flow sensor is factory-calibrated. FBLb is part of airflow control unit DCV-BLb and flow measurement unit DCV-MFb.

Why balance supply and extract air?

• Avoid pushing moist air into the walls (overpressure)
• Avoid drawing in cold or warm air into the building, which increases energy usage for climate control (underpressure)
• Avoid whistling around doors. In protective ventilation, the pressure differential between rooms must be correct to avoid unwanted air movements.

Features

• Used to measure, maintain, sum, or balance airflows in a way that provides great flexibility in designing room climate solutions.
• Can be part of a flow zone that includes up to 100 active supply air diffusers or other control units.
• Can add a positive or negative offset when regulating airflow.
• By selecting a specific function, the unit can act as a slave in relation to another flow control system within the zone.
• Parameters can be read and adjusted via the network and/or directly on the control unit via a connected user panel.
• Can be connected via Node ID to a communication bus (CAN) for access and communication with other cooperating nodes.
• Can communicate with other systems via LINDINTELL or via Gateway NCE with Modbus TCP/RTU.
• Equipped with Bluetooth® for communication via mobile devices using the LINDINSIDE app.
