Io Hvac Controls ZD-2412 Modulating Zone Damper 24x12

Product Description

The IO HVAC CONTROLS ZD-2412 is a modulating zone damper built for commercial HVAC zoning applications. It controls airflow within a duct system by adjusting blade position across a range of positions, allowing precise zone-by-zone temperature management rather than simple open/close operation. At 24 inches wide by 12 inches tall with a 6-inch depth, this damper fits standard commercial rectangular duct openings of that size. Weighing 11 pounds, it is a substantial unit suited for the airflow demands of commercial installations. Licensed HVAC technicians and sheet metal contractors are the typical installers.

This damper is designed for commercial zoning systems where modulating control is required to balance airflow across multiple zones. It is installed inline within rectangular ductwork as part of a multi-zone VAV or zoning control system. Typical applications include light commercial buildings, office suites, retail spaces, and similar facilities where individual zone comfort control is required. Its modulating capability makes it appropriate for systems using a zone control panel or building automation controller that outputs a variable control signal to the actuator.

Key Features

• Modulating operation allows variable blade positioning for precise airflow control
• 24 x 12 inch face dimensions fit standard commercial rectangular duct openings
• 6-inch depth accommodates typical duct installation clearances
• 11-pound construction indicates heavy-gauge commercial-grade build quality
• Suited for multi-zone commercial HVAC systems requiring individual zone regulation

Compatibility

Designed as an OEM-style modulating zone damper for commercial rectangular ductwork measuring 24 inches wide by 12 inches tall. Compatible with zoning control panels and building automation systems that provide a modulating control signal output.

Installation Notes

Installation should be performed by a licensed HVAC technician or sheet metal contractor familiar with commercial ductwork and zoning controls. Shut down the air handling unit and de-energize the zone control panel before beginning installation. The damper should be mounted inline with airflow direction as marked and secured to the duct with appropriate sheet metal fasteners and sealant to prevent air bypass. Verify the control signal wiring matches the actuator requirements before restoring power to the system.
