Io Hvac Controls LD-06 Round Zone Damper 6 Inch 3 Wire

Product Description

The IO HVAC CONTROLS LD-06 is a 6-inch round, 2-position zone damper designed for forced-air zoning systems in residential and light commercial HVAC applications. The damper uses a 3-wire actuator to drive the blade fully open or fully closed, with a built-in LED indicator that confirms actuator position at a glance. Licensed HVAC technicians install this damper as part of a multi-zone control system to regulate conditioned airflow to individual spaces, improving comfort and system efficiency. The 2-position design is straightforward to wire and commission with standard zone control boards.

The LD-06 is suited for round ductwork in residential split systems and packaged unit installations where zone control is applied. A 6-inch diameter fits standard trunk-and-branch duct layouts commonly found in single-family and multi-family construction. The integral LED simplifies troubleshooting during commissioning and service calls, allowing a technician to verify damper status without running signal checks at the control board. This damper is typically installed in the supply duct branch serving a single zone.

Key Features

• 6-inch round duct size fits standard residential branch duct runs
• 2-position operation drives blade fully open or fully closed for reliable zone control
• 3-wire actuator wiring is compatible with most residential zone control boards
• Built-in LED indicator confirms open or closed position without board-level diagnostics
• Compact actuator housing minimizes clearance requirements in tight plenum spaces

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for round duct forced-air zoning systems requiring a 6-inch, 2-position, 3-wire actuator damper.

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 inserted into the duct branch and secured per standard sheet metal practice before low-voltage actuator leads are connected to the zone board. Follow NEC guidelines for low-voltage wiring routing and separation from line-voltage conductors.
