Io Hvac Controls LD-2420-BM Zone Damper 24x20 Rectangular

Product Description

The IO HVAC CONTROLS LD-2420-BM is a rectangular two-position zone damper designed for forced-air zoning applications in residential and light commercial HVAC systems. Measuring 24 inches by 20 inches, this damper uses a 3-wire actuator with an integrated LED indicator to provide clear visual confirmation of blade position. Bottom-mount actuator placement simplifies installation in tight duct runs where side clearance is limited. Licensed HVAC technicians install this damper as part of a multi-zone control system, directing conditioned air to individual zones on demand.

This damper is suited for rectangular duct installations in residential split systems, heat pumps, and gas furnace applications where zone control is required. The two-position design opens and closes the blade fully, making it compatible with standard 24-volt zone control boards and thermostats. The LED indicator allows technicians to confirm actuator status during commissioning and troubleshooting without removing access panels.

Key Features

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect and lock out power to the air handler and zone control board before beginning installation. Verify duct opening dimensions match the damper body before cutting or modifying ductwork. Refer to the zone control manufacturer wiring diagram and applicable mechanical codes for low-voltage control wiring requirements.
