Description
The IO HVAC Controls D-12 12″ 2-Wire S/R Round Motorized Damper 24V is a zone control unit that regulates air passage within duct systems by opening or closing a single-blade mechanism based on control signals. It operates using a motor with a spring-return action, allowing automatic positioning during power changes for controlled distribution. In HVAC systems, it is used in zoning and ventilation setups to direct conditioned air to specific areas and maintain balanced temperature control. It is typically connected within ductwork through a two-wire configuration and supports efficient air management, quiet operation, and improved system responsiveness.
