Io Hvac Controls TD-2414 Rectangular Zone Damper 24x14

Product Description

The IO HVAC CONTROLS TD-2414 is a rectangular zone damper designed for zoned HVAC systems requiring precise airflow control at the duct level. Built to fit 24-inch by 14-inch duct openings, it ships with a Belimo 3-wire actuator that drives a 60-second open and close cycle. That actuator timing makes it well suited for residential and light commercial zoning panels that sequence multiple zones in sequence. Licensed HVAC technicians and sheet metal contractors are the primary installers. The damper integrates into zone control systems as a direct replacement or new-installation component, providing reliable blade actuation for balanced air distribution across conditioned spaces.

This damper is sized for 24-inch by 14-inch rectangular duct applications and is listed as compatible with Trane and American Standard zoning systems. It fits into zoned residential and light commercial forced-air systems where independent room or area temperature control is required. The Belimo 3-wire actuator provides spring-return or modulating control depending on the connected zone control panel. Install scenarios typically include new zoning retrofits on existing ductwork or replacement of failed dampers in existing Trane or American Standard zone systems.

Key Features

• 24-inch by 14-inch rectangular duct opening fits standard Trane and American Standard duct configurations
• Belimo 3-wire actuator included - no separate actuator purchase required
• 60-second actuation cycle for controlled, low-stress blade movement
• Drop-in replacement design for existing Trane and American Standard rectangular zone damper applications
• Packaged dimensions of 18 inches wide by 31 inches tall by 8 inches deep for straightforward staging and storage on the job

Compatibility

Designed for use with Trane and American Standard zoned forced-air HVAC systems requiring a 24-inch by 14-inch rectangular zone damper with a 3-wire Belimo actuator.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor. Power down the air handler, zone control panel, and any low-voltage wiring circuits before beginning work. Secure the damper into the duct using sheet metal screws and seal joints per local mechanical code requirements. Follow the actuator manufacturer wiring diagram for 3-wire connections to the zone control board and verify full open and close travel before restoring power.
