What type of VAV terminals is this controller designed for?

It is designed for fan‑powered VAV terminal units requiring pressure‑independent airflow control.

Does the controller require a separate actuator?

No. The actuator is integrated and factory‑mounted, simplifying installation.

Does it support demand‑controlled ventilation?

Yes. Demand‑controlled ventilation is supported when a field‑installed IAQ sensor is connected.

How does the controller simplify commissioning?

Automatic airflow transducer calibration and built‑in balancing tools significantly reduce commissioning time.
