It ships with an integrated 3-wire actuator and a status LED that allows technicians to confirm damper position at a glance without removing covers or using a meter. The bottom-mount actuator configuration suits duct runs where side-access is limited. Licensed HVAC technicians install this damper as part of a zone control system to regulate conditioned airflow to individual areas of a structure, improving comfort and system efficiency.\u003c\/p\u003e\n\u003cp\u003eThis damper is suited for residential and light-commercial forced-air zoning systems. The rectangular 18-by-14-inch blade fits standard duct openings of that nominal size. The two-position design means the actuator drives the blade fully open or fully closed on a call from the zone control board  -  there is no modulating or variable-position function. The bottom-mount actuator orientation is typically chosen when the damper is installed in a horizontal duct section with clearance below.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18-by-14-inch rectangular blade fits nominal duct openings of that size\u003c\/li\u003e\n  \u003cli\u003eTwo-position operation: fully open or fully closed on zone board command\u003c\/li\u003e\n  \u003cli\u003eIntegrated 3-wire actuator for straightforward wiring to zone control panels\u003c\/li\u003e\n  \u003cli\u003eStatus LED provides visual confirmation of damper position during commissioning and service\u003c\/li\u003e\n  \u003cli\u003eBottom-mount actuator configuration for installations with limited side clearance\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 and light-commercial forced-air zoning systems using two-position, 3-wire actuator-compatible zone control boards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a licensed HVAC technician. De-energize the zone control panel and air handler before wiring or mounting. Follow the zone control board manufacturer's wiring diagram for proper 3-wire actuator connections. Verify the damper blade moves freely and the LED indicates correct open and closed positions after power-up before closing the duct access.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Size\u003c\/strong\u003e: 18 x 14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper Type\u003c\/strong\u003e: Rectangular, Two-Position\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Wiring\u003c\/strong\u003e: 3-Wire\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Mount\u003c\/strong\u003e: Bottom Mount\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStatus Indicator\u003c\/strong\u003e: LED\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 21 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 21 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Depth\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 9 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-1814-BM\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67950531477810,"sku":"LD-1814-BM","price":261.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/87434551ce229afb9558d3baad520579_fa0507cd-965c-4204-a41d-9f8544a57f32.png?v=1791720701","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-ld-1814-bm-zone-damper-18x14-bottom-mount","provider":"Voomi Supply","version":"1.0","type":"link"}
