Io Hvac Controls LD-0806-BM Zone Damper 8x6 2 Position

Product Description

The IO HVAC CONTROLS LD-0806-BM is a rectangular two-position zone damper designed for ducted HVAC zoning systems. Measuring 8 inches by 6 inches, it controls airflow through a specific zone by opening or closing on command from a zone control board or thermostat. The unit uses a 3-wire actuator with an integrated LED indicator, allowing technicians to confirm damper state at a glance during commissioning or service calls. The bottom-mount actuator configuration positions the motor assembly below the duct for installations where clearance above the duct is limited. Licensed HVAC technicians typically install this damper as part of a multi-zone forced-air system.

This damper is suited for residential and light commercial forced-air zoning applications where individual rooms or areas require independent temperature control. It fits into rectangular duct runs and is installed in line with the supply duct feeding a specific zone. The bottom-mount actuator design makes it a practical choice for tight attic, basement, or mechanical closet installations where overhead access is restricted. The LED indicator aids in quick visual verification of open or closed position without requiring a test instrument.

Key Features

• 8 x 6 inch rectangular damper body sized for standard residential supply duct
• Two-position operation: fully open or fully closed for reliable zone control
• 3-wire actuator compatible with standard zone control boards
• Integrated LED indicator for visual confirmation of damper position
• Bottom-mount actuator for installations with limited overhead clearance

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for residential and light commercial rectangular duct zoning systems.

Installation Notes

Installation should be performed by a licensed HVAC technician. Power down the zone control system and set the thermostat to the off position before wiring or mounting the damper. The unit mounts in line with the supply duct and is typically secured with sheet metal screws before low-voltage wiring is connected to the zone board. Refer to local mechanical codes and the zone control manufacturer wiring diagram to ensure correct terminal connection of the 3-wire actuator circuit.
