Io Hvac Controls LD-2408-BM Zone Damper 24x8 2 Position

Product Description

The IO HVAC CONTROLS LD-2408-BM is a rectangular two-position zone damper designed for use in forced-air HVAC zoning systems. Measuring 24 inches wide by 8 inches tall, it uses a three-wire actuator to open and close the blade on demand from a zone control board or thermostat. An integrated LED provides a quick visual confirmation of actuator position, which saves diagnostic time during installation and service calls. The bottom-mount actuator configuration keeps the assembly accessible in tight duct runs. This unit is installed by licensed HVAC technicians building or servicing residential or light commercial zoned duct systems.

The LD-2408-BM fits into rectangular duct systems where individual zones require independent airflow control. It is well suited for residential zoning retrofits and new construction applications where a low-profile bottom-mount actuator is required. The two-position operation integrates directly with standard 24-volt zone control boards, opening fully on a call for conditioned air and closing when the zone is satisfied. The 24-by-8-inch face size accommodates a common rectangular duct dimension found in trunk-and-branch and extended-plenum layouts.

Key Features

• 24 x 8 inch rectangular damper body fits standard duct openings of that dimension
• Two-position operation for straightforward open/closed zone control
• Three-wire actuator compatible with standard 24-volt zone control boards
• Integrated LED indicator allows quick visual confirmation of actuator state
• Bottom-mount actuator placement improves accessibility in confined duct spaces

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for residential and light commercial forced-air zoning systems using standard 24-volt two-position control wiring.

Installation Notes

Installation should be performed by a qualified HVAC technician in accordance with applicable mechanical codes. Shut down the air handler and de-energize the zone control panel before making any wiring connections to the actuator. Verify that the duct opening matches the 24-by-8-inch damper face before securing the unit, and confirm three-wire low-voltage wiring is routed away from sharp duct edges. Consult the zone control board manufacturer's wiring diagram to correctly identify the power, common, and zone-call terminals.
