Io Hvac Controls SC-ZD-08 Modulating Zone Damper 8in

Product Description

The IO HVAC CONTROLS SC-ZD-08 is an 8-inch modulating zone damper built for commercial HVAC zoning applications. It controls airflow within a ducted system by adjusting blade position across a modulating range, allowing precise zone-by-zone temperature management rather than simple open/close switching. The unit measures 8 x 8 x 8 inches and weighs 5.2 pounds. Licensed HVAC technicians and commercial mechanical contractors are the primary installers. Its modulating action suits variable-air-volume and demand-controlled zoning strategies where staged airflow control is required.

The SC-ZD-08 is intended for commercial ducted HVAC systems where zoning control is needed across multiple occupied spaces. Its 8-inch round or rectangular duct interface fits standard commercial trunk-and-branch and plenum-bypass configurations. Typical installations include light commercial buildings, multi-zone rooftop unit systems, and retrofit zoning projects in office or retail environments. The modulating design supports integration with zone controllers or building automation systems that output a modulating control signal rather than a simple two-position command.

Key Features

• Modulating blade control for precise zone-by-zone airflow management
• 8-inch duct size fits standard commercial trunk-and-branch layouts
• Compact 8 x 8 x 8 inch form factor simplifies installation in tight plenum spaces
• Lightweight at 5.2 pounds for overhead and vertical duct mounting
• Compatible with zone controllers and building automation systems using modulating signal outputs

Compatibility

Designed as an OEM-style modulating zone damper for commercial ducted HVAC systems requiring 8-inch damper assemblies with modulating actuator control.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with commercial zoning systems and applicable mechanical codes. De-energize the HVAC system and confirm the supply fan is off before inserting the damper into the duct. Secure the unit per the manufacturer instructions using sheet metal screws appropriate for the duct material, and verify the control wiring to the zone controller is complete and properly routed before restoring power. Refer to local mechanical codes and the zone control system wiring guide for signal type and terminal assignments.
