It integrates a 9-inch round 2-position damper with a 120\/24-volt, 20 VA transformer and includes an outdoor temperature (ODT) humidistat. The panel controls fresh air intake by opening and closing the damper based on humidity and temperature conditions. Licensed HVAC technicians install this unit as part of a whole-home ventilation strategy, providing managed fresh air exchange while maintaining indoor comfort levels. The built-in transformer eliminates the need for a separate 24-volt power supply in most installations.\u003c\/p\u003e\n\u003cp\u003eThe io-fav-09-plus is suited for residential forced-air systems where fresh air ventilation control is required. It is typically installed in new construction or retrofit applications where indoor air quality improvements are a priority. The ODT humidistat allows the system to restrict fresh air intake during high-humidity outdoor conditions, helping prevent moisture-related issues inside the home. The 9-inch round damper fits standard round duct connections common in residential HVAC ductwork.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e9-inch round 2-position damper for standard residential duct connections\u003c\/li\u003e\n  \u003cli\u003eIntegrated 120\/24-volt, 20 VA transformer eliminates need for external low-voltage power supply\u003c\/li\u003e\n  \u003cli\u003eIncludes ODT humidistat for humidity-based fresh air control\u003c\/li\u003e\n  \u003cli\u003eRound damper profile compatible with common residential round ductwork\u003c\/li\u003e\n  \u003cli\u003eAll-in-one control panel simplifies fresh air ventilation wiring and commissioning\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation component for residential fresh air ventilation systems using 9-inch round duct connections and 24-volt control circuits.\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 control wiring and residential ventilation system design. Shut off power to the air handler and any connected control circuits before beginning installation. Follow local mechanical and electrical codes, including applicable sections of the IMC and NEC, when routing control wiring and mounting the damper assembly. Do not energize the unit until all duct connections are secured and wiring is verified against the manufacturer wiring diagram.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Round\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDamper Size\u003c\/strong\u003e: 9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTransformer Voltage\u003c\/strong\u003e: 120\/24 volts\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTransformer VA Rating\u003c\/strong\u003e: 20 VA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Residential\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIncluded Accessories\u003c\/strong\u003e: ODT Humidistat\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: io-fav-09-plus\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"IO HVAC CONTROLS","offers":[{"title":"Default Title","offer_id":51268954685746,"sku":"iO-FAV-09-PLUS","price":332.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/308910740.jpg?v=1780710909","url":"https:\/\/voomisupply.com\/products\/io-hvac-controls-io-fav-09-plus-fresh-air-ventilation-panel","provider":"Voomi Supply","version":"1.0","type":"link"}
