Io Hvac Controls TD-1408 Rectangular Zone Damper 14x8

Product Description

The IO HVAC CONTROLS TD-1408 is a rectangular zone damper designed for use in residential and light commercial zoned HVAC systems. It controls airflow through ductwork by opening and closing on demand from a zone control board or thermostat signal. The unit ships with a Belimo 3-wire actuator that operates on a 60-second cycle time, providing reliable, repeatable blade positioning. Packaged dimensions measure 10 inches wide, 21 inches tall, and 8 inches deep, with a shipping weight of 7 pounds. Licensed HVAC technicians are the primary installers of this component.

This damper is sized at 14 x 8 inches to fit standard rectangular duct openings of that dimension. It is suited for residential forced-air zoning applications where Trane or American Standard equipment is installed, and where the duct layout requires individual zone control. The integrated Belimo actuator eliminates the need for a separate actuator purchase, simplifying installation in retrofit and new-construction zoning projects alike.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with low-voltage zoning controls and duct fabrication. Shut down the air handler and de-energize the control board before wiring the actuator. The 3-wire actuator requires connection to the zone control board per the board manufacturer's wiring diagram. Follow all applicable local mechanical codes and manufacturer documentation during installation.
