It features a 3-wire actuator and an integrated LED indicator, allowing technicians to confirm damper position at a glance during commissioning and service calls. At 20 inches by 16 inches, this damper fits standard rectangular duct sizes common in residential and light commercial applications. It is installed by licensed HVAC technicians as part of a multi-zone forced-air system to control conditioned airflow to individual zones.\u003c\/p\u003e\n\u003cp\u003eThis damper is suited for residential and light commercial zoning installations where rectangular ductwork is used. The two-position design opens and closes fully in response to a zone controller or thermostat signal, making it a straightforward choice for new installations and retrofit zoning projects. The 3-wire actuator wiring scheme is compatible with most standard zone control boards, simplifying integration into existing or new control systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e20 x 16 inch rectangular form factor fits standard rectangular duct openings\u003c\/li\u003e\n  \u003cli\u003eTwo-position operation provides fully open or fully closed airflow control\u003c\/li\u003e\n  \u003cli\u003e3-wire actuator integrates with standard zone control boards\u003c\/li\u003e\n  \u003cli\u003eIntegrated LED indicator confirms damper status during installation and service\u003c\/li\u003e\n  \u003cli\u003eDesigned for ducted residential and light commercial zoning applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-install zone damper for rectangular duct zoning systems compatible with standard 3-wire zone control boards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed HVAC technician. Power down the air handler and zone control system before wiring or mounting the damper. The damper must be installed in a section of rectangular ductwork matching the 20 x 16 inch opening, with airflow direction observed per the unit markings. Follow applicable mechanical and electrical codes, including NEC low-voltage wiring guidelines, when connecting the 3-wire actuator to the zone controller.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Opening Size\u003c\/strong\u003e: 20 x 16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Type\u003c\/strong\u003e: 3-wire\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper Operation\u003c\/strong\u003e: 2-position (open\/close)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLED Indicator\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit Width\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit Height\u003c\/strong\u003e: 28 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUnit Depth\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 10 pounds\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: LD-2016\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67952904274226,"sku":"LD-2016","price":278.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/87434551ce229afb9558d3baad520579_ce24fef5-c73e-435a-92d9-a896c568cfde.png?v=1791754826","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-ld-2016-rectangular-zone-damper-20x16","provider":"Voomi Supply","version":"1.0","type":"link"}
