Io Hvac Controls LD-1210-BM Rectangular Zone Damper

Product Description

The IO HVAC CONTROLS LD-1210-BM is a 2-position rectangular zone damper designed for forced-air zoning systems in residential and light commercial HVAC applications. The damper ships with a 3-wire actuator and an integrated LED status indicator, allowing technicians to confirm blade position at a glance during commissioning and service. The bottom-mount actuator configuration suits installations where duct geometry or plenum clearance restricts side-mount access. At 6 pounds, the unit is straightforward to handle during single-tech installation in overhead or tight-space duct runs.

This damper is sized at 12 inches by 10 inches, fitting standard rectangular duct of the same nominal dimensions. It is suited for ducted zoning layouts where a zone control board or thermostat controller sends a 3-wire signal to open or close the blade. Typical applications include residential split systems, air handlers, and packaged units where independent room-by-room temperature control is required. The bottom-mount actuator position makes this model particularly useful in horizontal duct runs with limited lateral clearance.

Key Features

• 2-position operation: fully open or fully closed blade for straightforward zoning control
• 3-wire actuator interface compatible with standard zone control boards
• Integrated LED indicator for quick visual confirmation of damper position
• Bottom-mount actuator design accommodates restricted side-clearance duct installations
• Nominal 12 inch by 10 inch rectangular duct sizing for a direct-fit installation

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for standard 12 inch by 10 inch rectangular ductwork in residential and light commercial forced-air zoning systems.

Installation Notes

Installation should be performed by a licensed HVAC technician. Power down the air handler and zone control board before connecting or disconnecting actuator wiring. Verify duct dimensions match the nominal damper size before securing to prevent blade binding. Follow local mechanical codes and the zone control system manufacturer wiring diagram when connecting the 3-wire actuator leads.
