It ships with a 3-wire actuator and an integrated LED indicator, allowing technicians to confirm damper position at a glance without additional test equipment. The damper blade opens or closes fully in response to a zone controller signal, directing conditioned air to occupied zones and shutting off flow to unoccupied ones. At 6 pounds, the unit is sized for duct openings measuring 12 inches wide by 8 inches tall. HVAC technicians and sheet metal installers are the primary trades handling this component.\u003c\/p\u003e\u003cp\u003eThe LD-1208 fits into forced-air duct systems where independent zone temperature control is required. It is suited for new construction zoning installations and retrofit applications where an existing straight duct section can accept a flanged damper insert. The 3-wire actuator configuration is compatible with standard 2-position zone control boards that supply a 24-volt signal to open and a separate signal to close, making wiring straightforward for technicians already familiar with conventional zoning panels.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2-position operation opens or closes fully for precise zone airflow control\u003c\/li\u003e\n\u003cli\u003eIntegrated LED indicator confirms open or closed actuator position without a meter\u003c\/li\u003e\n\u003cli\u003e3-wire actuator wiring matches standard 2-position zone controller outputs\u003c\/li\u003e\n\u003cli\u003e12-inch by 8-inch rectangular blade fits common residential trunk-and-branch duct sizes\u003c\/li\u003e\n\u003cli\u003eCompact actuator package at 6 pounds for easier handling in tight duct chases\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-install zone damper for residential and light commercial forced-air duct systems requiring 2-position rectangular dampers with 3-wire actuator control.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a licensed HVAC technician or qualified sheet metal installer. Always shut off the air handler or furnace and de-energize the zone control panel before wiring or mounting the damper. The unit should be installed in a straight duct section with adequate clearance around the actuator housing to allow full blade travel. Low-voltage wiring connections must comply with applicable NEC requirements and the zone controller manufacturer's wiring diagram.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuct Opening Width\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDuct Opening Height\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 10 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 19 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: 6 pounds\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\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndicator\u003c\/strong\u003e: LED\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBlade Shape\u003c\/strong\u003e: Rectangular\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: LD-1208\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67950400504114,"sku":"LD-1208","price":213.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/87434551ce229afb9558d3baad520579_0f666ea6-b3bb-4953-82b7-31bff15c0a9d.png?v=1791716209","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-ld-1208-rectangular-zone-damper-12x8","provider":"Voomi Supply","version":"1.0","type":"link"}
