Io Hvac Controls LD-1612 Rectangular Zone Damper 16x12

Product Description

The IO HVAC CONTROLS LD-1612 is a 16 x 12 inch rectangular two-position zone damper designed for forced-air zoning systems in residential and light commercial HVAC applications. It ships with an integrated 3-wire actuator and a status LED for quick visual confirmation of blade position. Two-position dampers operate in fully open or fully closed mode, making them a straightforward solution for zone-controlled duct runs. The actuator is factory-mounted to the damper body, reducing field assembly time. Licensed HVAC technicians and sheet metal contractors are the typical installers for this type of component.

The LD-1612 fits 16 x 12 inch rectangular duct openings, which are common trunk-line branch takeoffs and main supply duct runs in residential split systems and packaged units. It is well-suited for multi-zone forced-air systems where a zone control board or thermostat system switches the damper open or closed based on zone demand. The 3-wire actuator configuration is compatible with standard low-voltage zone control panels that use a spring-return or powered-open, powered-close wiring scheme.

Key Features

• Rectangular two-position blade design for fully open or fully closed zone control
• Fits 16 x 12 inch rectangular duct openings
• Integrated 3-wire actuator eliminates separate actuator mounting
• Status LED provides visual confirmation of damper position without tools
• Factory-assembled actuator and damper body for faster field installation

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for rectangular duct systems requiring a 16 x 12 inch two-position damper with a 3-wire low-voltage actuator.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor. Power down the air handler or furnace and de-energize the zone control panel before making any wiring connections. The damper should be secured to the duct using sheet metal screws around the collar, following standard sheet metal practices. Low-voltage wiring must comply with NEC guidelines for Class 2 circuits and the zone control manufacturer wiring diagram.
