Io Hvac Controls LD-2216-BM Zone Damper 22x16 Inch

Product Description

The IO HVAC CONTROLS LD-2216-BM is a rectangular two-position zone damper sized at 22 x 16 inches, designed for forced-air zoning applications in residential and light commercial HVAC systems. It uses a 3-wire actuator with a built-in LED indicator, allowing the technician to confirm damper position at a glance without removing covers or tracing signals. The bottom-mount actuator configuration makes it accessible in tight duct runs where side access is restricted. HVAC technicians install this damper to control airflow in individual zones, balancing comfort and efficiency across a ducted system.

This damper fits into rectangular duct installations where zoning controls divide a single air handler or furnace into independently controlled areas. It is suited for new construction and retrofit zoning projects in residential homes and light commercial buildings. The two-position operation means the damper drives fully open or fully closed on command from a zone control board, making it straightforward to wire and commission in standard zoning setups. The LED indicator on the actuator gives installers and service techs a fast visual status check during startup and troubleshooting.

Key Features

• 22 x 16 inch rectangular form factor fits standard duct openings of that size
• Two-position operation drives fully open or fully closed for simple zone control
• 3-wire actuator wiring integrates with most residential and light commercial zone control boards
• Built-in LED indicator provides at-a-glance damper position confirmation
• Bottom-mount actuator placement improves access in confined duct installations

Compatibility

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

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with forced-air zoning systems. Power down the air handler and zone control board before making any wiring connections. Secure the damper firmly in the duct opening and verify the actuator is fully seated in the bottom-mount position before restoring power. Confirm LED indicator status during system startup to verify proper operation before closing out the installation.
