Io Hvac Controls SC-ZD-1212 Modulating Zone Damper 12x12

Product Description

The IO HVAC CONTROLS SC-ZD-1212 is a modulating zone damper designed for commercial HVAC zoning applications. It controls airflow within a duct system by opening and closing to precise positions, allowing independent temperature control across multiple zones. The damper measures 12.125 inches wide by 12.125 inches deep with a 5.875-inch height profile, and weighs 8.1 pounds. It is sized for 12 x 12 duct openings and is installed by licensed HVAC technicians as part of a commercial zoning system paired with a zone controller or building automation system.

This damper is suited for commercial zoning installations where modulating airflow control is required across multiple conditioned spaces. Unlike on/off bypass dampers, a modulating damper moves to intermediate positions, allowing proportional airflow delivery. Typical applications include multi-zone rooftop unit systems, commercial VAV-style zoning setups, and light commercial retrofit zoning projects where precise zone-by-zone airflow management is needed.

Key Features

• Modulating operation allows proportional airflow control rather than simple open/close switching
• Sized for standard 12 x 12 inch duct openings for straightforward installation into existing ductwork
• Compact 5.875-inch depth profile accommodates tight mechanical spaces
• Commercial-grade construction suited for multi-zone commercial HVAC systems
• 8.1-pound unit weight supports secure mounting without excessive structural load on duct

Compatibility

Designed as an OEM-style modulating zone damper for commercial HVAC zoning systems using 12 x 12 inch duct connections.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with commercial zoning systems. Shut down the air handling unit and de-energize all associated controls before installing or servicing the damper. The damper must be wired to a compatible zone controller per the controller manufacturer's wiring diagram and applicable NEC requirements. Confirm airflow direction alignment with the damper's marked orientation before securing to ductwork.
