Io Hvac Controls ld-12 Round Zone Damper 12 Inches

Product Description

The IO HVAC CONTROLS ld-12 is a 12-inch round, 2-position zone damper designed for residential HVAC zoning systems. It operates on a 3-wire actuator and includes an LED status indicator for quick visual confirmation of blade position. The damper controls airflow in ductwork by moving between a fully open and fully closed position, allowing zone controllers to direct conditioned air only where it is needed. Licensed HVAC technicians and zoning system installers are the primary trade users for this component.

This damper is intended for residential forced-air zoning applications. It fits 12-inch round duct runs and is suited for new zoning installations or replacement of failed dampers in existing systems. The 2-position, spring-return or power-open design is a common configuration in single-stage and multi-stage residential zoning setups where precise modulation is not required and a simple open-closed operation meets the system design.

Key Features

• 12-inch round blade fits standard 12-inch round ductwork
• 2-position operation: fully open or fully closed for straightforward zone control
• 3-wire actuator compatible with standard residential zone controllers
• Integrated LED indicator confirms damper position at a glance
• Designed for residential HVAC zoning applications

Compatibility

Designed as an OEM-style zone damper for use in residential forced-air HVAC zoning systems requiring a 12-inch round, 2-position damper with a 3-wire actuator.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with residential zoning systems. Shut down the air handler or furnace and de-energize the zone control panel before installing or wiring the damper. Secure the damper in the duct run per the manufacturer direction and connect the 3-wire actuator leads to the appropriate zone controller terminals. Verify LED status after restoring power to confirm proper open and close operation before closing the duct access.
