Built in a 12-inch by 8-inch duct size, it uses a three-wire actuator to drive the blade between fully open and fully closed positions. An integrated LED indicator allows technicians to confirm actuator status at a glance without additional test equipment. Licensed HVAC technicians install this damper as part of a zoned comfort system controlled by a compatible zone control panel.\u003c\/p\u003e\n\u003cp\u003eThe ld-1208 is suited for residential zoning applications where a single air handler or furnace serves multiple zones through a branched duct layout. The rectangular form factor fits standard rectangular duct trunk lines and branch runs. The three-wire wiring scheme supports spring-return or powered-open and powered-close operation depending on control panel configuration. This damper is sized for common residential duct runs where airflow must be modulated by zone demand.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eRectangular two-position blade for full open or full closed zone control\u003c\/li\u003e\n  \u003cli\u003eThree-wire actuator supports powered-open and powered-close control wiring\u003c\/li\u003e\n  \u003cli\u003eIntegrated LED indicator confirms actuator position status during commissioning and service\u003c\/li\u003e\n  \u003cli\u003e12-inch by 8-inch duct size fits standard residential rectangular duct runs\u003c\/li\u003e\n  \u003cli\u003eDesigned for residential forced-air zoning system installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation zone damper for residential rectangular duct zoning systems using three-wire actuator control panels.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician. Shut down the air handler or furnace and de-energize the zone control panel before wiring or mounting the damper. Verify duct dimensions before installation to confirm a proper fit in the rectangular duct opening. Follow the control panel manufacturer wiring diagram for correct three-wire actuator terminal connections and observe applicable mechanical and electrical codes.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Rectangular\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDuct Size\u003c\/strong\u003e: 12 inches x 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Type\u003c\/strong\u003e: 3-Wire Actuator\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperation\u003c\/strong\u003e: 2-Position (Open\/Closed)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLED Indicator\u003c\/strong\u003e: Yes\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Residential\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-1208\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":51268817715506,"sku":"LD-1208","price":214.77,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308910644.jpg?v=1780706655","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-ld-1208-zone-damper-12x8-in-3-wire","provider":"Voomi Supply","version":"1.0","type":"link"}
