The unit ships with a Belimo 3-wire actuator mounted to the bottom of the damper body, providing 60-second travel time for reliable zone-by-zone airflow control. The damper opening measures 18 inches wide by 14 inches tall, making it a direct fit for standard rectangular duct runs used in Trane and American Standard zoning installations. Licensed HVAC technicians install this damper as part of a multi-zone control system, typically paired with a zone control panel and zone thermostats.\u003c\/p\u003e\n\u003cp\u003eThe TD-1814-BM is intended for rectangular duct zoning in residential and light commercial forced-air systems. It is specifically designed to match the dimensional and wiring requirements of Trane and American Standard zone control systems. The Belimo 3-wire actuator communicates with zone control boards that issue open and close commands, allowing individual zones to be conditioned independently. Typical installations include split-level homes, additions, and multi-story light commercial buildings where load balancing across zones is required.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e18 inch by 14 inch rectangular damper opening sized for standard duct transitions in Trane and American Standard systems\u003c\/li\u003e\n  \u003cli\u003eBelimo 3-wire actuator included, factory-mounted to the bottom of the damper body\u003c\/li\u003e\n  \u003cli\u003e60-second actuator travel time provides smooth, controlled airflow modulation\u003c\/li\u003e\n  \u003cli\u003eBottom-mount actuator configuration suits installations where side or top access is restricted\u003c\/li\u003e\n  \u003cli\u003eDrop-in replacement form factor reduces field modification time during retrofits\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement zone damper compatible with Trane and American Standard rectangular duct zoning systems requiring an 18 inch by 14 inch damper with a Belimo 3-wire actuator interface.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician familiar with low-voltage zoning controls and duct fabrication. Shut down the air handler and de-energize the zone control panel before cutting into the duct and securing the damper. Verify that the control board is compatible with a 3-wire Belimo actuator signal before making low-voltage wiring connections. Follow local mechanical codes and the zone control panel manufacturer wiring diagram for proper actuator terminal assignments.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper Width\u003c\/strong\u003e: 18 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper Height\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Type\u003c\/strong\u003e: Belimo 3-Wire\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Travel Time\u003c\/strong\u003e: 60 seconds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActuator Mount Position\u003c\/strong\u003e: Bottom Mount\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: 8 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: TD-1814-BM\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":67948872368434,"sku":"TD-1814-BM","price":303.05,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/50bbd6f74b2edbde3fa9d504fe30cd5d_5081c2f9-757d-4b66-8ff9-4ee6f3c2c35c.jpg?v=1791675387","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-td-1814-bm-rectangular-zone-damper-18x14","provider":"Voomi Supply","version":"1.0","type":"link"}
