Central Forced Air
So you have a Central Forced Air HVAC system
Cello is fully capable of managing all residential central forced air heating systems irrespective of the furnace efficiency; modulating or non-modulating. Cello operates within the furnace manufacturer specifications.

How does it work?
Cello is not a thermostat. It works seamlessly with your existing old or smart (Nest, Ecobee, and Honeywell) thermostat, in addition to a network of optional wireless sensors and inline dampers installed in specific areas of your home.
Cello makes old and smart thermostats smarter.
Airflow is controlled by installing patent-pending, battery-powered in line Cello Dampers in selected register boots based on your desired energy and operational modes. Cello’s inline dampers are easily installed below your existing register grille eliminating the need to change your register covers with plastic motorized dampers, allowing you to maintain your desired aesthetics.
The Cello Damper comes in several duct sizes, ranging from 3 to 6 inches.
Cello monitors the health of your furnace and AC or heat pump, allowing you to continuously receive and view critical performance data on the Cello App or any web browser.
Support and Requirements
The two main Cello components required for any central forced air installations are the Cello Core and Cello Damper.
Cello supports three energy modes; Max Savings, Balanced, and Max Comfort. You can play your Cello in either manual or automatic mode. Cello Sensors are only required if you opt to play your Cello in automatic mode.
