Io Hvac Controls TD-3210 Rectangular Zone Damper 32x10

Product Description

The IO HVAC CONTROLS TD-3210 is a rectangular zone damper engineered for zoned HVAC ducting systems in residential and light commercial applications. It ships with a Belimo 3-wire actuator, providing on/off zone control directly out of the box. The damper measures 32 inches by 10 inches and is designed to interface with Trane and American Standard zoning systems. Licensed HVAC technicians install this component as part of a multi-zone forced-air setup, where individual zones require independent airflow control. The included Belimo actuator connects to low-voltage zone control boards and responds to standard open/close signals.

This damper is suited for rectangular ductwork in forced-air systems using Trane or American Standard zone controls. It fits into new construction and retrofit installations where zoning panels manage multiple areas of a building independently. The 32-by-10-inch blade size accommodates medium to larger trunk or branch duct runs. HVAC technicians will typically integrate this damper with a zone control board, thermostat wiring, and a bypass damper arrangement to maintain proper static pressure across the system.

Compatibility

Designed for use with Trane and American Standard rectangular ductwork zoning systems. Compatible with standard low-voltage zone control boards that support 3-wire actuator wiring.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with low-voltage zoning controls. Shut down the air handler and de-energize the zone control board before mounting the damper or connecting actuator wiring. Verify the duct opening dimensions match the damper blade size before securing the unit. Follow the zone control manufacturer wiring diagram for the 3-wire actuator connection and confirm proper open/close operation before closing out the installation.
