Modes of Operation

Cello Inline Damper position is manually controlled from either the Cello app or cloud.

The Cello Inline 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 Inline 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. No additional room sensors needed to achieve airflow balance.

Room-by-Room Temperature Control

For room by room temperature control, Cello PoE Brick units are installed in each of the room’s returns behind the grille.

Occupancy Based Air Quality Control

For air quality control, Cello PoE Brick units are installed in each of the room’s returns behind commercial off the shelf grilles with replaceable dust filters. In addition, a properly sized HEPA filter is installed close to the furnace return intake with the addition of a Cello controlled booster fan to compensate for static pressure loss.
