Io Hvac Controls LD-2814-BM Zone Damper 28x14 in 2 Position

Product Description

The IO HVAC CONTROLS LD-2814-BM is a rectangular 2-position zone damper designed for residential and light commercial HVAC zoning systems. It accepts a 3-wire actuator with an integrated LED status indicator, giving technicians a quick visual confirmation of damper position during commissioning and service calls. Measuring 28 inches by 14 inches, the damper fits standard rectangular duct openings of that size. The bottom-mount actuator configuration provides clearance in tighter duct chases where side-mount access is restricted. At 10 pounds, it is robust enough for long-term cycling duty in forced-air zoning applications.

This damper is suited for forced-air zoning installations in residential and light commercial buildings where individual zones require independent airflow control. It is typically installed inline within rectangular supply or return ductwork as part of a multi-zone system controlled by a zone control board or thermostat panel. The bottom-mount actuator orientation makes it a practical choice when overhead or side clearances are limited. HVAC technicians handling zoning retrofits or new-construction zoning layouts will find the LED indicator useful for verifying open and closed positions without a separate test tool.

Key Features

• 28 inch by 14 inch rectangular damper blade sized for standard duct openings
• 2-position operation - fully open or fully closed for straightforward zone control
• 3-wire actuator interface compatible with standard zone control boards
• Integrated LED status indicator confirms damper position at a glance
• Bottom-mount actuator design accommodates restricted side and top clearances
• 10-pound construction supports durable, long-cycle zoning duty

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for rectangular forced-air duct systems requiring a 28 inch by 14 inch 2-position damper with a 3-wire actuator interface.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with forced-air zoning systems. Disconnect power to the air handler and zone control board before wiring the actuator to avoid damage to control circuitry. Confirm the damper blade orientation and actuator mounting position prior to securing the unit in the ductwork to ensure proper open and closed travel. Verify LED indicator function after restoring power as part of system commissioning.
