Io Hvac Controls HD-2416-BM Zone Damper 24x16 Two-position

Product Description

The IO HVAC CONTROLS HD-2416-BM is a rectangular two-position zone damper sized for 24 x 16 inch duct openings. It uses a 2-wire actuator mounted on the bottom of the damper body, which simplifies wiring in tight plenum or duct shaft installations. Zone dampers of this type open and close in response to a thermostat or zone control board signal, directing conditioned air to specific zones within a forced-air HVAC system. The bottom-mount actuator configuration is suited for installations where side access is restricted. At 11 pounds, this is a solid, duct-ready assembly that installs without additional actuator hardware.

This damper is intended for rectangular supply or return duct runs in residential and light commercial zoned forced-air systems. It fits 24 x 16 inch duct openings and is appropriate for new construction or retrofit zoning projects. HVAC technicians and sheet metal contractors typically install this damper during system commissioning or when adding zone control to an existing ducted system. The 2-wire actuator wires directly into a compatible zone control panel, making field wiring straightforward.

Key Features

• Fits 24 x 16 inch rectangular duct openings for direct drop-in installation
• Two-position operation opens and closes fully for on/off zone control
• 2-wire actuator reduces wiring complexity at the zone control panel
• Bottom-mount actuator placement accommodates restricted side-access duct locations
• Ships as a complete assembly - no separate actuator purchase required

Compatibility

Designed as an OEM-style replacement or new-install zone damper for residential and light commercial forced-air zoning systems using two-position, 2-wire actuator control panels.

Installation Notes

Installation is typically performed by a licensed HVAC technician or qualified sheet metal contractor. Shut down the air handler and de-energize the zone control panel before installing or replacing the damper. Secure the damper into the duct opening using sheet metal screws and seal all seams with approved duct sealant or foil tape per local mechanical codes. Verify actuator wiring matches the zone control board terminals before restoring power.
