Io Hvac Controls TD-1210-BM Rectangular Zone Damper 12x10

Product Description

The IO HVAC CONTROLS TD-1210-BM is a rectangular zone damper designed for use in residential and light commercial HVAC zoning systems. Built to fit 12-inch by 10-inch duct openings, it ships with a Belimo 3-wire actuator mounted at the bottom of the damper body. The actuator operates on a 60-second cycle time, providing reliable, controlled airflow regulation across individual zones. Licensed HVAC technicians install this damper as part of a zoning control system to balance comfort and energy efficiency throughout a structure. The bottom-mount configuration simplifies installation in tight duct runs where side access is restricted.

This damper is suited for residential and light commercial forced-air systems requiring zone control. It is specifically designed for compatibility with Trane and American Standard zoning systems, making it a direct-fit solution for those platforms. Typical installation scenarios include retrofit zoning projects and new construction where duct runs require individual zone shutoff or modulation. The rectangular profile accommodates standard rectangular duct configurations common in trunk-and-branch and plenum-fed systems.

Compatibility

Designed for use with Trane and American Standard rectangular duct zoning systems in residential and light commercial applications requiring a 12-inch by 10-inch damper opening.

Installation Notes

Installation should be performed by a licensed HVAC technician. Power down the air handler and zoning control board before beginning any wiring or damper installation. The 3-wire Belimo actuator requires connection to a compatible zone control panel; consult the zoning panel manufacturer wiring diagram before making connections. Ensure the damper is properly seated and secured in the duct opening before restoring system power.
