Io Hvac Controls ld-2420 Zone Damper 24x20 in 2 Position

Product Description

The IO HVAC CONTROLS ld-2420 is a rectangular 2-position zone damper designed for residential HVAC zoning systems. It measures 24 inches x 20 inches and uses a 3-wire actuator with an integrated LED indicator. The damper controls airflow in ductwork by switching between fully open and fully closed positions, enabling independent temperature control across multiple zones. Licensed HVAC technicians install this damper as part of a zone control system, typically paired with a zone control board and zone thermostats. The LED provides a quick visual confirmation of damper position during commissioning and service calls.

This damper is suited for residential forced-air HVAC applications where zoning is required to manage comfort in different areas of a home. The 24-inch x 20-inch rectangular form factor fits standard rectangular ductwork of that size. It is commonly installed in branch ducts or main trunk lines serving dedicated zones, and works with low-voltage zone control systems. The 3-wire actuator wiring allows the zone controller to drive the damper to both open and closed positions on command.

Key Features

• 24 inches x 20 inches rectangular form factor fits standard duct openings of that size
• 2-position operation — fully open or fully closed for straightforward zone airflow control
• 3-wire actuator wiring supports positive open and positive close signals from zone controllers
• Integrated LED indicator for quick visual confirmation of damper status during installation and service
• Designed for residential HVAC zoning applications

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for residential rectangular duct zoning systems requiring a 24-inch x 20-inch 2-position damper with a 3-wire actuator.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with low-voltage zone control wiring. Shut down the air handling unit and de-energize the zone control panel before connecting or disconnecting the actuator wiring. Ensure the damper is properly secured and sealed within the ductwork to prevent air bypass. Follow local mechanical and electrical codes during installation and commissioning.
