Io Hvac Controls SC-ZD-07 Modulating Zone Damper 7 in

Product Description

The IO HVAC CONTROLS SC-ZD-07 is a 7-inch modulating zone damper designed for commercial HVAC zoning applications. It regulates airflow within a duct system by adjusting blade position across a range of positions rather than operating in a simple open-or-closed mode. This modulating design gives the system precise airflow control in multi-zone setups. Licensed HVAC technicians and commercial mechanical contractors install this damper as part of a variable-air-volume or multi-zone control system. At 4.5 pounds and compact overall dimensions, it is sized for integration into standard commercial ductwork runs.

The SC-ZD-07 is suited for commercial HVAC zoning systems where independent temperature control across multiple zones is required. Typical installations include light commercial buildings, office spaces, and multi-room facilities that use a central air handler with zone-based distribution. It fits into a 7-inch round or equivalent duct section and works in conjunction with a zone controller or building automation panel. This damper is intended for modulating control signal inputs, not simple two-position switching applications.

Key Features

• Modulating operation allows proportional airflow control beyond simple open or closed positions
• 7-inch duct size fits standard commercial duct configurations
• Compact form factor at 7.25 x 7.25 x 8.125 inches (W x H x D) simplifies installation in tight plenum spaces
• Lightweight at 4.5 pounds for easier single-technician handling during installation
• Commercial-grade construction suitable for continuous-duty zoning operation

Compatibility

Designed as an OEM-style modulating zone damper for use in commercial HVAC zoning systems with 7-inch duct connections. Consult the zone controller manufacturer specifications to confirm signal type compatibility before installation.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with commercial zoning systems and applicable mechanical codes. Shut down and lock out the air handler before installing or servicing the damper. Verify that the control signal type from the zone controller matches the damper actuator requirements before making low-voltage wiring connections. Seal all duct connections after mounting to prevent air bypass and confirm blade movement through the full modulating range during system commissioning.
