Io Hvac Controls LD-1410-BM Rectangular Zone Damper

Product Description

The IO HVAC CONTROLS LD-1410-BM is a 14 x 10 inch rectangular two-position zone damper designed for ducted HVAC zoning systems. It uses a 3-wire actuator with an integrated LED status indicator and a bottom-mount configuration. The damper controls airflow within a specific zone by opening and closing on demand from a zone control board or thermostat. This unit is sized for medium-capacity duct runs and is installed by licensed HVAC technicians performing zoning work on residential or light commercial forced-air systems.

This zone damper is suited for rectangular duct applications in split-system or air handler installations where independent zone control is required. The two-position operation means the damper drives fully open or fully closed based on a 24-volt control signal. The bottom-mount actuator placement makes it accessible in tight duct chases and overhead installations. The LED indicator allows technicians to confirm actuator status during commissioning without additional test equipment. It is commonly used in multi-zone residential systems and light commercial retrofit zoning projects.

Key Features

• 14 x 10 inch rectangular form factor fits standard medium duct openings
• Two-position operation provides full open and full closed airflow control
• 3-wire actuator supports standard zone control board wiring
• Integrated LED indicator confirms actuator position during commissioning and service
• Bottom-mount actuator design allows installation in space-constrained duct runs
• Package dimensions of 18 x 17 x 8 inches accommodate the assembled unit with actuator

Compatibility

Designed as an OEM-style replacement or new-install zone damper for rectangular ducted residential and light commercial forced-air HVAC zoning systems using standard 3-wire, 24-volt zone control boards.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with ducted zoning systems. Shut down the air handler and de-energize the control system before mounting the damper or making any wiring connections. Verify that the duct opening matches the 14 x 10 inch damper size before installation. Follow the zone control board manufacturer wiring diagram for the 3-wire actuator connection and confirm LED status after restoring power during system commissioning.
