Io Hvac Controls LD-2216 Zone Damper 22x16 3 Wire

Product Description

The IO HVAC CONTROLS LD-2216 is a rectangular two-position zone damper designed for ducted HVAC zoning systems. It ships with an integrated 3-wire actuator and a status LED, giving installers a visible confirmation of blade position without opening the duct. The damper blade moves between fully open and fully closed, making it a straightforward solution for on/off zone control in forced-air residential and light commercial systems. At 11 pounds, the unit is a substantial assembly suited for larger duct trunk applications. Licensed HVAC technicians and sheet metal contractors are the typical installers.

The LD-2216 fits a 22-inch by 16-inch rectangular duct opening, a common trunk or branch size in multi-zone forced-air systems. It is well suited for new construction zoning installations and retrofit zoning projects where an existing rectangular duct run is being divided into independently controlled zones. The 3-wire actuator configuration is compatible with standard zone control boards that use a power-open, power-close, or spring-return wiring scheme, depending on how the board is configured.

Key Features

• Two-position operation for reliable fully open or fully closed zone control
• Integrated 3-wire actuator eliminates the need for a separate actuator assembly
• Status LED provides visual blade position confirmation at the damper body
• 22-inch by 16-inch rectangular duct size covers large trunk and branch applications
• Robust construction at 11 pounds for stable installation in high-velocity duct systems

Compatibility

Designed as an OEM-style zone damper for rectangular ducted forced-air HVAC systems requiring two-position control. Verify zone control board wiring scheme before installation to confirm 3-wire actuator compatibility.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor. Shut down the air handler and de-energize the zone control panel before wiring the actuator. The damper body must be mounted with adequate clearance on all sides to allow full blade travel and future actuator service. Follow all applicable local mechanical codes and the zone control board manufacturer wiring instructions for 3-wire actuator connections.
