Io Hvac Controls TD-1406 Rectangular Zone Damper 14x6

Product Description

The IO HVAC CONTROLS TD-1406 is a rectangular zone damper designed for residential and light commercial zoning systems. It ships with a 60-second Belimo 3-wire actuator mounted and ready for installation. The damper controls airflow through a 14-inch by 6-inch duct section, allowing individual zone temperature management within a forced-air HVAC system. Licensed HVAC technicians install this component as part of a multi-zone control setup, connecting it to a zone control board that opens and closes the blade on demand. The 3-wire actuator configuration supports both open and closed end-switch signaling, which is required by most zone controllers for proper operation.

This damper is suited for zoning applications in residential split systems and light commercial forced-air installations where duct sizes match the 14-inch by 6-inch opening. It is specified as a replacement or new-installation damper for Trane and American Standard zoned systems. Typical installations place this damper in a rectangular trunk line or branch duct where the zone controller needs to regulate conditioned airflow to a specific area of the building.

Key Features

• 14-inch by 6-inch rectangular damper opening matches standard duct sizing for residential and light commercial systems
• Integrated 60-second Belimo 3-wire actuator provides reliable open and close end-switch feedback to zone controllers
• 3-wire actuator wiring supports zone control boards requiring end-switch confirmation
• Designed as a compatible replacement for Trane and American Standard zoned forced-air systems
• Factory-mounted actuator reduces field assembly time during installation

Compatibility

Designed as a compatible zone damper replacement for Trane and American Standard rectangular duct zoning systems requiring a 14-inch by 6-inch damper with a 60-second Belimo 3-wire actuator.

Installation Notes

Installation should be performed by a licensed HVAC technician. Shut down the air handler and disconnect power to the zone control system before mounting the damper or connecting actuator wiring. Secure the damper body to the duct using sheet metal screws and seal edges with approved HVAC tape or mastic to prevent air bypass. Connect the 3-wire actuator leads to the zone control board according to the control board manufacturer's wiring diagram.
