Model ZTWD
2-Zone Thermostat with Integrated Equipment and Zone Control

New Residential Constuction

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 low cost temperature sensor installed in the upstairs zone and a touchscreen thermostat installed in the downstairs living space zone.

The thermostat monitors the temperature downstairs and the upstairs 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.

Low Cost

Half the cost of traditional zoning.

Simple Installation

Cuts installation time by eliminating the hassles of zoning.

Automatic or Manual Operation

Thermostat automatically controls the distribution of heating or cooling. Or, the homeowner can manually direct more heating or cooling to the upstairs or downstairs zone to improve comfort and save energy.

Night Comfort Option

Saves 30% in energy at night and improves comfort by automatically distributing more heating or cooling to the upstairs zone and 30% less to the unoccupied downstairs zone and uses the upstairs sensor to control the heating and cooling calls.
