Io Hvac Controls D-Z1-2212 Zone Damper Assembly 22x12

Product Description

The IO HVAC CONTROLS D-Z1-2212 is a two-position zone one damper assembly designed for use in ducted HVAC zoning systems. It controls airflow to a single zone by opening or closing on demand from a zone control board or thermostat signal. The assembly measures 22 inches wide by 12 inches tall by 6 inches deep and weighs 9.5 pounds. HVAC technicians install this damper as part of a multi-zone forced-air system to direct conditioned air where it is needed while blocking flow to unoccupied or satisfied zones. The two-position operation means the blade is either fully open or fully closed, making it straightforward to wire and commission.

This damper assembly is suited for residential and light commercial zoning applications in rectangular supply or return ductwork. It is a Zone 1 designated damper, meaning it is typically wired to the primary zone output of a compatible zone control panel. Installers use it in new construction zoning layouts or retrofit projects where a single duct run requires independent temperature control. The 22-inch by 12-inch face size accommodates standard rectangular duct openings of that dimension.

Key Features

• Two-position operation: blade is fully open or fully closed for simple, reliable zone control
• Zone 1 designation for direct wiring to primary zone output on a compatible control board
• 22 inches wide by 12 inches tall face size fits standard rectangular ductwork of the same dimension
• 6-inch depth accommodates typical duct installation clearances
• 9.5-pound assembly weight suitable for standard duct hangers and supports

Compatibility

Designed as an OEM-style replacement or new-installation damper for rectangular ducted HVAC zoning systems requiring a two-position Zone 1 damper in a 22-inch by 12-inch duct opening.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with ducted zoning systems and low-voltage control wiring. Shut off power to the air handler and zone control panel before installing or connecting the damper. The damper must be mounted in the duct with airflow direction aligned to the manufacturer arrow on the assembly housing. Low-voltage control wiring should comply with NEC Article 725 requirements for Class 2 circuits.
