Io Hvac Controls LD-2416-BM Zone Damper 24x16 in 3 Wire

Product Description

The IO HVAC CONTROLS LD-2416-BM is a rectangular two-position zone damper designed for ducted HVAC zoning systems. The unit measures 24 x 16 inches and ships with a 3-wire actuator and an integrated LED indicator that provides instant visual feedback on blade position. Bottom-mount actuator placement keeps the unit accessible in tight mechanical spaces. Licensed HVAC technicians install this damper as part of multi-zone forced-air systems where individual zones require independent airflow control. At 11 pounds, the assembly is substantial enough for commercial-grade duct runs while still fitting standard residential trunk and branch configurations.

This damper is suited for rectangular duct applications in residential and light commercial forced-air systems. It functions as a zone control device, opening and closing in response to a 24-volt zone control board or thermostat signal. The two-position operation means the blade moves fully open or fully closed on demand, making it appropriate for straightforward zone isolation rather than modulating airflow control. Typical installations include supply trunk branches, main distribution ducts, and custom zoning retrofits where the 24 x 16 inch duct size is present.

Key Features

• Rectangular 24 x 16 inch duct opening fits standard residential and light commercial trunk sizes
• Two-position operation delivers fully open or fully closed blade control
• 3-wire actuator supports standard 24-volt zone control board wiring
• Integrated LED indicator gives technicians instant visual confirmation of blade position
• Bottom-mount actuator placement improves serviceability in confined duct spaces

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for rectangular ducted forced-air systems using 24-volt 3-wire zone control wiring.

Installation Notes

Installation is performed by licensed HVAC technicians following applicable mechanical codes. Shut down the air handler and de-energize the zone control panel before wiring or mounting the damper. Verify duct dimensions match the 24 x 16 inch opening before installation to ensure a proper seal. Consult the zone control board manufacturer wiring diagram to confirm 3-wire terminal assignments before applying power.
