Equipped with a 2-wire actuator, it opens and closes on demand from a zone control board or thermostat signal, directing conditioned air to specific zones within a duct system. The damper measures 30 inches wide by 12 inches tall at the duct opening and ships at a weight of 12 pounds. Licensed HVAC technicians and sheet metal contractors are the primary installers of this type of equipment. It is built for reliable on\/off airflow control rather than modulating operation.\u003c\/p\u003e\u003cp\u003eThe HD-3012 is suited for residential and light commercial forced-air zoning applications where rectangular duct runs require individual zone control. It fits into existing rectangular ductwork of the corresponding size and integrates with standard 2-wire zone control systems. Typical installations involve multi-zone split systems, heat pumps, or gas furnace setups where separate thermostats govern individual areas of a structure. The straightforward 2-wire wiring configuration simplifies integration with most common zone control panels.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eTwo-position operation opens and closes the damper blade fully for on\/off zone control\u003c\/li\u003e\n\u003cli\u003e2-wire actuator simplifies wiring to zone control boards\u003c\/li\u003e\n\u003cli\u003eRectangular design fits 30 x 12 inch duct openings\u003c\/li\u003e\n\u003cli\u003eShips at 12 pounds, indicating robust construction for long-term duct installation\u003c\/li\u003e\n\u003cli\u003eSuitable for residential and light commercial forced-air zoning systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation zone damper for rectangular ductwork requiring a 30 x 12 inch two-position damper with a 2-wire actuator interface.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified sheet metal contractor. Power down the air handler and zone control panel before making any wiring connections. Ensure the damper is oriented correctly relative to airflow direction as marked on the unit before fastening to the duct. Follow all applicable local mechanical codes and manufacturer wiring diagrams when connecting the 2-wire actuator leads to the zone control board.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuct Opening Width\u003c\/strong\u003e: 30 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuct Opening Height\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActuator Type\u003c\/strong\u003e: 2-Wire\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOperation Type\u003c\/strong\u003e: Two-Position\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 37 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Depth\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 12 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: HD-3012\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67948337299762,"sku":"HD-3012","price":358.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/e5da16f12b9e92e16483a7f802f4c9e0_b8e69a73-fabd-4cc9-b358-244bfd128d84.jpg?v=1791662371","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-hd-3012-zone-damper-30x12-in-2-wire","provider":"Voomi Supply","version":"1.0","type":"link"}
