Io Hvac Controls TD-2612-BM Rectangular Zone Damper 26x12

Product Description

The IO HVAC CONTROLS TD-2612-BM is a rectangular zone damper engineered for use in residential and light commercial HVAC zoning systems. Sized at 26 x 12 inches, it ships with a Belimo 3-wire actuator factory-mounted in the bottom position, providing a 60-second run time for reliable, repeatable blade travel. The 3-wire actuator configuration supports both open and close power signals, making it well suited for zone control panels that require positive positioning in both directions. Licensed HVAC technicians install this damper as part of a multi-zone duct system to regulate conditioned airflow to individual zones.

This damper is designed for rectangular duct applications where Trane or American Standard zoning equipment is specified. It fits into new-construction and retrofit zoning projects in residential and small commercial buildings. The bottom-mount actuator orientation is suited for installations where access from below the ductwork is the preferred service position. The 60-second actuator timing is compatible with standard zone control board sequencing used in typical forced-air systems.

Key Features

• 26 x 12 inch rectangular damper sized for standard duct openings in Trane and American Standard zoning applications
• Factory-installed Belimo 3-wire actuator for positive open and close control
• 60-second actuator run time for smooth, controlled blade travel
• Bottom-mount actuator orientation for installations with under-duct service access
• Designed as a direct replacement damper for Trane and American Standard zone systems

Compatibility

Designed for use with Trane and American Standard rectangular duct zoning systems. Intended as a replacement or new-installation zone damper where a 26 x 12 inch rectangular damper with a bottom-mount Belimo 3-wire actuator is specified.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with forced-air zoning systems. Shut down the air handler and de-energize the zone control panel before installing or wiring the actuator. Verify that the duct opening matches the 26 x 12 inch damper frame dimensions before securing the unit. Follow the zone control panel manufacturer wiring diagram for 3-wire actuator connections and confirm actuator travel direction during commissioning.
