 "summary": "The Airflow-IQ AiQ-TD-xxC pairs a Ruskin TDP05K thermal dispersion airflow probe with a VA*B24-BAC 'RAMS' air measurement actuator that holds an airflow setpoint. The actuator talks BACnet IP on its RJ-45 port or BACnet MS/TP (or Modbus RTU) on the junction-box terminals. The BMS sends an airflow command as a 0-100% setpoint and reads airflow, velocity, damper position and the differential pressure reading.",
