Io Hvac Controls TD-2212-BM Rectangular Zone Damper 22x12

Product Description

The IO HVAC CONTROLS TD-2212-BM is a rectangular zone damper engineered for 22-inch by 12-inch duct openings in residential and light commercial HVAC zoning systems. It ships with a Belimo 3-wire actuator mounted at the bottom of the damper body and operates on a 60-second cycle time. The Belimo actuator provides reliable, repeatable blade positioning for zone-by-zone airflow control. Licensed HVAC technicians install this damper as part of a multi-zone forced-air system, connecting it to a zone control board to manage conditioned airflow to individual spaces.

This damper is designed for use in rectangular supply or return duct applications where Trane and American Standard zoning systems are common. The bottom-mount actuator configuration suits installations where access from below the duct is preferred. Typical applications include residential split systems and light commercial forced-air builds requiring independent zone control. The damper integrates with standard 3-wire zone control wiring schemes used in most contemporary zoning panels.

Key Features

• Rectangular damper sized for 22-inch by 12-inch duct openings
• Belimo 3-wire actuator included, factory-mounted at the bottom of the damper body
• 60-second actuator cycle time for controlled, low-noise blade travel
• Bottom-mount actuator configuration for installations with limited side or top clearance
• Compatible with Trane and American Standard zoning system architectures

Compatibility

Designed for use with Trane and American Standard rectangular duct zoning applications. Confirm duct opening dimensions of 22 inches by 12 inches before installation.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with low-voltage zoning wiring and duct modification work. Shut down the air handler and de-energize the zone control panel before wiring or mounting the damper. Secure the damper into the duct opening per the manufacturer instructions and verify blade travel is unobstructed before restoring power. Follow all applicable local mechanical codes and manufacturer wiring diagrams when connecting the 3-wire actuator leads to the zone control board.
