Io Hvac Controls ZD-2214 Modulating Zone Damper 22x14

Product Description

The IO HVAC CONTROLS ZD-2214 is a modulating zone damper built for commercial HVAC zoning applications. It controls airflow by varying blade position across a continuous range, allowing precise zone-by-zone temperature management rather than simple open/close operation. At 22 inches wide by 14 inches tall, this damper fits standard commercial duct openings in that size class. Weighing 11 pounds, it is a robust unit suited for ducted air distribution systems in light commercial and larger residential installations. Licensed HVAC technicians and sheet metal contractors are the primary installers.

The ZD-2214 is designed for commercial zoning systems where modulating control is required to balance airflow across multiple zones. It fits into ducted supply or return applications where a 22 x 14 inch rough opening is present. Typical installation scenarios include rooftop unit zoning, air handler distribution systems, and multi-zone commercial builds where a zone controller or building automation system drives damper position. The 6-inch depth accommodates standard duct transitions without major modification.

Key Features

Compatibility

Designed as an OEM-style replacement or new-installation damper for commercial ducted HVAC zoning systems requiring a 22 x 14 inch modulating zone damper.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor. Shut down the air handling unit and de-energize all associated control wiring before beginning installation. Verify actuator control signal type and voltage against the zone controller specifications before making electrical connections. Follow local mechanical codes and manufacturer wiring guidelines for low-voltage control circuits.
