Io Hvac Controls LD-2210-BM Rectangular Zone Damper

Product Description

The IO HVAC CONTROLS LD-2210-BM is a 22 x 10 inch rectangular two-position zone damper designed for forced-air zoning systems. It ships with a 3-wire actuator and an integrated LED indicator that confirms blade position at a glance. The bottom-mount actuator configuration allows installation in tight duct runs where side-mount clearance is limited. Licensed HVAC technicians install this damper as part of a multi-zone control system to regulate conditioned airflow to individual areas of a building, improving comfort and system efficiency.

This damper is suited for residential and light commercial forced-air zoning applications. It fits into rectangular ductwork where a 22 x 10 inch opening is required. The two-position design means the blade drives fully open or fully closed on a call from the zone controller, making it appropriate for standard on/off zoning panels. Installers working with ducted split systems, packaged units, or air handlers will find this a direct-fit solution for new zoning installations or zone damper replacements in existing duct systems.

Key Features

• 22 x 10 inch rectangular damper body sized for standard residential and light commercial duct openings
• Two-position operation drives blade fully open or fully closed for straightforward zone control
• 3-wire actuator provides power-open, power-close, or spring-return wiring flexibility depending on system requirements
• Integrated LED indicator gives a visual confirmation of damper blade position without opening the duct
• Bottom-mount actuator orientation suits duct runs with restricted side clearance
• Package dimensions of 17 x 8 x 25 inches allow straightforward staging and storage on the job site

Compatibility

Designed as an OEM-style replacement or new-install zone damper for rectangular forced-air duct systems requiring a 22 x 10 inch two-position damper with a 3-wire actuator interface.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with forced-air zoning systems and low-voltage control wiring. Shut down the air handler or furnace and de-energize the zone control panel before making any wiring connections. Confirm duct opening dimensions match the damper frame size before cutting into existing ductwork. Refer to the zone controller manufacturer wiring diagram to correctly assign the 3-wire actuator leads to power-open, power-close, and common terminals.
