Io Hvac Controls LD-1206 Rectangular Zone Damper 12x6

Product Description

The IO HVAC CONTROLS LD-1206 is a 12 x 6 inch rectangular two-position zone damper designed for forced-air HVAC zoning systems. It includes a 3-wire actuator and an LED indicator that confirms damper position at a glance. The damper opens and closes on demand from a zone control board, directing conditioned air to specific zones within a residential or light commercial duct system. Licensed HVAC technicians install this damper as part of a multi-zone system to balance airflow, improve comfort, and reduce energy waste. The LED simplifies commissioning and troubleshooting without removing the unit from the duct.

The LD-1206 is suited for rectangular supply or return duct branches in residential and light commercial forced-air systems. Its 12 x 6 inch duct opening fits standard sheet metal trunk-and-branch layouts. The two-position design keeps installation straightforward: the damper is either fully open or fully closed based on the zone controller signal. It is a common choice for retrofit zoning projects where duct infrastructure already exists and new zone control hardware is being added.

Key Features

• 12 x 6 inch rectangular duct opening fits standard sheet metal branch ducts
• Two-position operation for simple open/closed zone control
• 3-wire actuator connects directly to most residential zone control boards
• Integrated LED indicator confirms open or closed position for fast commissioning and diagnostics
• Compact actuator profile: 9 inches wide, 6.75 inches tall, 18.5 inches deep

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for rectangular forced-air duct systems requiring a 12 x 6 inch two-position damper with a 3-wire actuator interface.

Installation Notes

Installation is performed by a licensed HVAC technician. Power down the air handler and zone control panel before wiring the actuator. The damper is typically fastened into an inline duct section using sheet metal screws, and the 3-wire harness is routed back to the zone control board per the board manufacturer wiring diagram. Follow local mechanical codes and SMACNA duct construction standards for support and sealing of the installed damper.
