This Zone One damper controls airflow to a designated zone by moving between a fully open and fully closed position, allowing a zoning control panel to direct conditioned air only where it is needed. Measuring 20 inches wide by 12 inches tall with a depth of 6 inches and weighing 9 pounds, this is a robust, duct-installed assembly suited for rectangular trunk or branch duct applications. Licensed HVAC technicians install this component as part of a multi-zone system build or retrofit.\u003c\/p\u003e\n\u003cp\u003eThis damper assembly is intended for rectangular duct runs in forced-air heating and cooling systems where independent zone temperature control is required. It functions as the Zone One damper in a zoned HVAC layout, responding to signals from a compatible zoning control panel to open or close airflow to that zone. Typical installations include residential systems with multiple thermostats or light commercial applications requiring separate comfort zones. The 20 x 12 inch face size fits a standard 20 x 12 duct opening directly, reducing the need for adapters in new construction or retrofit work.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo-position operation  -  fully open or fully closed for straightforward zone control\u003c\/li\u003e\n  \u003cli\u003e20 x 12 inch face dimensions sized to fit standard rectangular duct openings directly\u003c\/li\u003e\n  \u003cli\u003e6 inch depth accommodates typical duct clearances in residential and light commercial installations\u003c\/li\u003e\n  \u003cli\u003eSolid 9-pound construction provides durability in continuous cycling applications\u003c\/li\u003e\n  \u003cli\u003eDesignated Zone One configuration integrates directly into IO HVAC CONTROLS zoning panel wiring schemes\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style zone damper for rectangular forced-air duct systems requiring two-position zone control. Specific panel and system compatibility should be confirmed against the IO HVAC CONTROLS zoning panel documentation prior to installation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician familiar with forced-air zoning systems. Power the zoning control panel down completely before making low-voltage wiring connections to the damper actuator. The damper must be mounted in the duct with airflow direction matching the arrow or marking on the assembly body. Refer to local mechanical codes and the zoning panel manufacturer wiring diagram to confirm correct Zone One terminal assignments before restoring power.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 20 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDepth\u003c\/strong\u003e: 6 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 9 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperation Type\u003c\/strong\u003e: Two-Position\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: IO HVAC CONTROLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: D-Z1-2012\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67951959114034,"sku":"D-Z1-2012","price":456.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ed39787339732d479be92f2ce474482b_afe89d80-f11c-489f-93cf-56b17c1db98b.png?v=1791742326","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-d-z1-2012-zone-damper-assembly-20x12","provider":"Voomi Supply","version":"1.0","type":"link"}
