Io Hvac Controls HD-2406-BM Zone Damper 24x6 2 Wire Bottom Mount

Product Description

The IO HVAC CONTROLS HD-2406-BM is a rectangular two-position zone damper designed for ducted HVAC zoning systems. It controls airflow by opening or closing fully in response to a signal from a zone control board, directing conditioned air only where the thermostat calls for it. The damper operates on a 2-wire actuator wired directly to the zone controller, simplifying field installation. The bottom-mount actuator configuration suits duct runs where top or side access is limited. At 7 pounds, the unit is sturdy enough for permanent installation in residential and light commercial ductwork without adding excessive load to the duct system.

This damper is sized at 24 x 6 inches, making it appropriate for rectangular branch or trunk duct sections of matching dimensions. It is typically installed in forced-air residential systems that use zoning to independently condition multiple areas or floors. HVAC technicians install this unit during new zoning system buildouts or when retrofitting an existing forced-air system with zone control. The 2-wire actuator design is compatible with standard zone control boards that provide a 24-volt signal to drive two-position dampers.

Compatibility

Designed as an OEM-style replacement or new-install zone damper for rectangular ducted forced-air HVAC zoning systems requiring a 24 x 6 inch two-position damper with a bottom-mount 2-wire actuator.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with ducted zoning systems. Power down the zone control board and air handler before making any wiring connections to the actuator. Secure the damper to the duct section with sheet metal screws and seal all joints with approved duct tape or mastic to prevent air bypass. Verify correct actuator travel and damper blade position at startup before returning the system to normal operation.
