The unit operates on 24 volts and uses a powered motor in both directions — powered open and powered closed — eliminating reliance on spring return. A 3-wire hookup connects via common, power-open, and power-closed legs. Built-in LED indicators display blade position: red signals fully closed and green signals fully open. These LEDs are failsafe-referenced, meaning they illuminate only after the blade reaches its full open or full closed position, giving technicians a reliable visual confirmation during commissioning and service.\u003c\/p\u003e\n\u003cp\u003eThe EURD-14 is suited for residential and light commercial HVAC zoning applications where air quality control and precise damper positioning are required. With a 14-inch round form factor, it fits standard round duct runs in forced-air systems. HVAC technicians typically install this damper as part of a zone control system, integrating it with a zone control board and low-voltage thermostat wiring. The two-position, 24-volt design makes it compatible with most standard zone control panels that support powered-open, powered-closed damper operation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTwo-position motor operation: powered open and powered closed — no spring return required\u003c\/li\u003e\n  \u003cli\u003e24-volt motor compatible with standard low-voltage zone control systems\u003c\/li\u003e\n  \u003cli\u003e3-wire connection: common, power-open leg, and power-closed leg\u003c\/li\u003e\n  \u003cli\u003eLED position indicators — red for closed, green for open\u003c\/li\u003e\n  \u003cli\u003eFailsafe LED logic: indicators illuminate only at full blade travel, confirming complete actuation\u003c\/li\u003e\n  \u003cli\u003e14-inch round single-blade design for standard round duct installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style motorized round damper replacement or new-install component for 24-volt HVAC zone control systems requiring powered-open, powered-closed two-position damper operation.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician. Disconnect and lock out power to the air handler and zone control panel before installing or servicing the damper. Verify that the zone control board supports powered-open, powered-closed operation on the 24-volt damper output before wiring. Follow local mechanical codes and the zone control manufacturer wiring diagram when connecting the 3-wire motor leads.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProduct Type\u003c\/strong\u003e: URD Motorized Damper\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBlade Type\u003c\/strong\u003e: Single blade\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 14 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Voltage\u003c\/strong\u003e: 24 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMotor Operation\u003c\/strong\u003e: Two-position, powered open and powered closed\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWires to Motor\u003c\/strong\u003e: 3\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Air Quality\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: EWC CONTROLS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: EURD-14\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"EWC CONTROLS","offers":[{"title":"Default Title","offer_id":51345783390514,"sku":"EURD-14","price":224.56,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310554877.jpg?v=1782062829","url":"https:\/\/voomisupply.com\/products\/ewc-controls-eurd-14-urd-motorized-round-damper-14-in","provider":"Voomi Supply","version":"1.0","type":"link"}
