Product DescriptionThe IO HVAC CONTROLS SC-ZD-06 is a 6-inch modulating zone damper designed for commercial HVAC zoning applications. It regulates airflow within ductwork by opening and closing in variable increments rather than operating in a simple open/closed mode. This modulating action allows precise control over conditioned air distribution across multiple zones. Licensed HVAC technicians install this damper as part of a zoned forced-air system, typically paired with a zone control panel and low-voltage actuator signals. The unit measures 6.25 inches wide by 6.125 inches high by 8 inches deep and weighs 4.1 pounds.The SC-ZD-06 is suited for commercial zoning systems where individual zone temperature management is required. It fits into standard 6-inch round or compatible rectangular duct configurations and is appropriate for light commercial and larger residential forced-air installations. Its modulating design supports variable air volume (VAV) style control strategies where supply air delivery must be adjusted continuously rather than switched on and off.Key FeaturesModulating operation allows variable airflow control rather than simple open/closed switching6-inch duct size suits common commercial and large residential duct trunk and branch configurationsCompact footprint at 6.25 x 6.125 x 8 inches fits in tight plenum and duct chase installationsLightweight construction at 4.1 pounds simplifies overhead and in-duct mountingCommercial-grade designation supports demanding multi-zone system requirementsCompatibilityDesigned as an OEM-style replacement or new-installation modulating zone damper for 6-inch commercial forced-air zoning systems.Installation NotesInstallation should be performed by a licensed HVAC technician familiar with commercial zoning systems and low-voltage control wiring. Shut down the air handler and de-energize all control circuits before installing or servicing the damper. Secure the damper to the duct using approved fasteners and seal all joints per local mechanical code requirements. Verify actuator signal compatibility with the zone control panel before restoring power.Technical SpecificationsDuct Size: 6 inchesWidth: 6.25 inchesHeight: 6.125 inchesDepth: 8 inchesWeight: 4.1 poundsOperation Type: ModulatingApplication: CommercialStandard InformationBrand: IO HVAC CONTROLSManufacturer Part Number: SC-ZD-06
