The IO HVAC CONTROLS bal-1614-bm is an electronic balancing damper designed to regulate airflow in ducted HVAC distribution systems. At 16 x 14 inches, this damper fits larger rectangular duct runs where precise zone control or system balancing is required. The electronic actuator allows the blade position to be adjusted remotely or via a building automation signal, eliminating the need for manual damper adjustment after installation. Licensed HVAC technicians install this type of component during new construction, system retrofits, or zoning upgrades.
This damper is suited for commercial and residential HVAC applications that require controlled airflow distribution across multiple zones or branches. Typical installations include variable air volume systems, zoned forced-air systems, and duct balancing projects where static pressure and airflow must be managed across supply or return trunks. The 16 x 14 inch frame size accommodates high-volume branch or main duct runs commonly found in light commercial and larger residential systems.
Designed as an OEM-style replacement or new-installation electronic balancing damper for rectangular duct systems requiring a 16 x 14 inch opening.
Installation should be performed by a licensed HVAC technician familiar with duct system design and low-voltage control wiring. Disconnect power to the air handler and any associated zone control boards before installing or wiring the actuator. Ensure the duct opening matches the damper frame dimensions and that the actuator control wiring is run in accordance with NEC requirements for low-voltage systems. Do not force the blade past its mechanical stops during initial setup.
