Io Hvac Controls HD-2414-BM Zone Damper 24x14 Inch

Product Description

The IO HVAC CONTROLS HD-2414-BM is a rectangular two-position zone damper sized at 24 inches by 14 inches, designed for use in forced-air HVAC zoning systems. It ships with a 2-wire actuator mounted on the bottom of the damper assembly. Two-position dampers cycle fully open or fully closed in response to a zone thermostat call, directing conditioned air only where it is needed. The bottom-mount actuator configuration suits duct installations where side access is limited. This damper is installed by licensed HVAC technicians as part of a multi-zone residential or light commercial air distribution system.

This damper fits into rectangular duct runs where zone control is required, typically in residential split systems or light commercial forced-air applications. The 24-by-14-inch nominal duct size accommodates higher-capacity branch or trunk duct runs. HVAC contractors integrate this damper with a zone control board and individual thermostats to balance airflow across multiple zones. The 2-wire actuator simplifies field wiring by requiring only a power and common connection from the zone control panel.

Key Features

• 24 inch by 14 inch rectangular nominal duct size suits larger branch and trunk duct runs
• Two-position operation provides fully open or fully closed airflow control per zone
• 2-wire actuator reduces wiring complexity at the zone control panel
• Bottom-mount actuator placement accommodates installs with limited side clearance
• Compatible with standard residential and light commercial zone control boards

Compatibility

Designed as an OEM-style replacement or new-install zone damper for rectangular duct zoning systems requiring a 24-by-14-inch two-position damper with a bottom-mount 2-wire actuator.

Installation Notes

Installation should be performed by a qualified HVAC technician. Shut down the air handler or furnace and de-energize the zone control panel before wiring or mounting the damper. Secure the damper firmly in the duct run and verify actuator travel is unobstructed before restoring power. Confirm wiring polarity and voltage requirements match the zone control board specifications prior to commissioning.
