Half the Cost and Labor of Traditional Zoning

How It Works

A typical installation includes two modulating zoning dampers installed in the trunks feeding the upstairs and downstairs zones, a wireless damper control module installed near the equipment, a wireless temperature sensor installed in the upstairs zone and a touchscreen  thermostat installed in the downstairs living space zone using the existing thermostat cable.

The thermostat monitors the upstairs and downstairs temperatures during heating and cooling calls. If the temperatures differ by 2 degrees or more, the thermostat automatically distributes 2% more heating or cooling to the zone that needs it every 2 minutes. When more heating or cooling is distributed upstairs, the upstairs damper fully opens and the downstairs damper partially closes, forcing more heating or cooling to the upstairs zone.

When more heating or cooling is distributed downstairs, the downstairs damper fully opens and the upstairs damper partially closes, forcing more heating or cooling to the downstairs zone.

Modulating Zoning dampers never close but dynamically adjust to find the right distribution to provide a comfortable home and save energy in every season.
