User interfaces
Look for details about a specific interface via its product name and product description.

• Login localy directly to the controller via mobile phone with the LINDINSIDE app
• Via Gate way NCE and Lindinventʼs central unit running LINDINSPECT®
• Other parent system via Gateway NCE and Modbus-RTU or ModbusTCP
• Fixed panel FLOCHECK P, wired directly to SPLb

Troubleshooting and Alarm Notification

Systems with LINDINSPECT® log and set alarm flags in case of deviations. Alarms can also be indicated both acoustically and optically by connecting user panel FLOCHECK P to the controller.

Functional chart
DCV-SPb on main duct for supply air:
Cell offices with supply air via active diffusers and extract air to a common corridor. Two fixed extract airflows with supply air from the corridor.

Active diffusers

• Controls the climate in each office according to setpoints

• Notifies collaborating nodes of their current airflow
  DCV-SPb

• Continuously measures the pressure in the duct section

• Maintains the duct pressure according to setpoints via damper control

• DCV-SPb is commissioned for pressure control
  DCV-CFb

• Maintains a constant duct pressure to maintain the fixed set extract airflow

• Measures and reports via CAN the fixed airflow

• Note: DCV-CFb is always commissioned for pressure control and flow measurement
  DCV-BLb

• Measures the extract airflow from the corridor

• Reads the reported DCV-CFb airflow

• Sums its own measured airflow with the measured flow from DCV-CFb

• Maintains the desired balancing of the supply air-flow through damper control

DCV-BLb is commissioned for flow balancing.
