This automatic damper integrates seamlessly with Resideo TrueZONE zoning systems to divide your home into separate comfort zones, allowing independent temperature control for different areas. The motorized damper blade opens and closes automatically based on thermostat demand, directing conditioned air only where needed to reduce energy waste and improve overall system efficiency. The spring-return mechanism ensures the damper closes in the event of power loss, preventing unwanted airflow.

Ideal for retrofit applications or new construction, the ZD20X12TZ installs directly into rectangular ductwork with minimal modifications. The damper's low electrical draw makes it suitable for use with standard residential zone control boards and transformers.
