Modes of Operation

Cello Air damper position is manually controlled from either the Cello app or cloud.

The Cello Air damper position changes based on a schedule entered by the end user. The schedule can be entered via the Cello app or cloud.

All installed Cello Air dampers are synchronized and intelligently controlled via the Cello cloud. Airflow balancing is achieved using built in sensors and AI algorithms running on the Cello cloud. There are no additional room sensors needed to achieve airflow balance.

Exposed Duct Runs

Exposed duct runs can now be controlled with damper actuators from Belimo, Honeywell, and other manufacturers. The actuators are controlled via the Cello cloud in tandem with the Cello Stealth Dampers.
