Io Hvac Controls HD-2222-PO Zone Damper 22x22 Powered Open

Product Description

The IO HVAC CONTROLS HD-2222-PO is a 22 x 22 inch rectangular two-position zone damper designed for powered-open operation in forced-air HVAC zoning systems. It controls conditioned airflow to individual zones by opening on command and returning to the closed position when de-energized, making it a standard component in multi-zone residential and light commercial duct systems. The damper ships ready for integration with standard zone control boards and is installed by licensed HVAC technicians during new zoning installations or system retrofits.

This damper is suited for rectangular ductwork applications in residential and light commercial forced-air systems where zone-by-zone temperature control is required. The powered-open, spring-return design means the damper defaults to the closed position on power loss, which supports fail-safe zoning operation. It is a common choice for retrofit zoning projects where existing rectangular duct runs need damper integration without major duct modification.

Key Features

• 22 x 22 inch rectangular form factor fits standard square duct configurations
• Powered-open, spring-return operation defaults to closed on power loss for fail-safe performance
• Two-position actuator provides simple open/closed zone control compatible with standard zoning panels
• Designed for multi-zone forced-air heating and cooling distribution systems
• Packaged dimensions of 26 x 28 x 8 inches accommodate standard freight handling

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for rectangular forced-air duct systems requiring two-position powered-open control.

Installation Notes

Installation should be performed by a qualified HVAC technician. Shut down the air handler and disconnect power to the zone control system before mounting or wiring the damper. Secure the damper to the ductwork using sheet metal screws and seal all edges with foil tape or approved duct sealant to prevent air bypass. Verify actuator wiring connections at the zone control board before restoring power.
