Io Hvac Controls TD-2412-BM Rectangular Zone Damper 24x12

Product Description

The IO HVAC CONTROLS TD-2412-BM is a rectangular zone damper engineered for residential and light commercial zoned HVAC systems. The unit measures 24 inches wide by 12 inches tall and ships with a factory-mounted Belimo 3-wire actuator that operates on a 60-second stroke cycle. The bottom-mount actuator configuration positions the drive mechanism below the damper blade assembly, keeping the unit accessible in tight duct runs. Licensed HVAC technicians install this damper into supply or return trunk lines as part of a multi-zone control system, where it opens and closes on a demand signal from the zone controller to direct conditioned air to individual zones.

This damper is designed for Trane and American Standard zoning applications. It fits rectangular duct openings of 24 inches by 12 inches and integrates directly with zone control panels that accept a standard 3-wire actuator wiring configuration. Typical installations include residential split systems and light commercial air handlers where multiple zones require independent temperature control. The 60-second actuator timing is compatible with most residential zone control boards that expect standard open/close cycle speeds.

Key Features

• 24 x 12 inch rectangular form factor fits standard trunk duct openings
• Factory-mounted Belimo 3-wire actuator eliminates field actuator selection and pairing
• 60-second actuator stroke cycle compatible with residential zone control panels
• Bottom-mount actuator position improves accessibility in confined mechanical spaces
• Designed for Trane and American Standard zoning system applications

Compatibility

Designed for use with Trane and American Standard rectangular duct zoning systems requiring a 24 x 12 inch damper with a Belimo 3-wire bottom-mount actuator.

Installation Notes

Installation should be performed by a licensed HVAC technician in accordance with applicable mechanical codes. 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 with sheet metal screws and seal all edges with foil-backed tape to prevent bypass air. Verify actuator wiring polarity and stroke direction at the zone control board before returning the system to service.
