Io Hvac Controls HD-2216 Zone Damper 22x16 2 Wire

Product Description

The IO HVAC CONTROLS HD-2216 is a rectangular two-position zone damper with a 2-wire actuator, designed for use in residential and light commercial HVAC zoning systems. Zone dampers control airflow through individual duct branches, allowing different areas of a building to be heated or cooled independently. The HD-2216 fits a 22 x 16 inch rectangular duct opening and uses a 2-wire actuator for straightforward open/close operation. Licensed HVAC technicians and zoning system installers are the primary installers of this component.

This damper is suited for rectangular duct systems where independent zone control is required. It operates in a two-position mode, fully opening or fully closing airflow to a designated zone based on a signal from a zone control board or thermostat system. The 2-wire actuator simplifies wiring compared to multi-wire spring-return designs. Typical applications include residential forced-air systems with zone control panels and light commercial multi-zone HVAC installations.

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for rectangular duct systems requiring two-position airflow control in residential or light commercial HVAC zoning applications.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with forced-air zoning systems. Shut down the air handling unit and disconnect power to the zone control board before installing or replacing the damper. Secure the damper to the ductwork using sheet metal screws and seal all joints with foil-backed tape or mastic per applicable mechanical codes. Verify actuator wiring to the zone control panel matches the system wiring diagram before restoring power.
