Io Hvac Controls TD-1212 Rectangular Zone Damper 12x12

Product Description

The IO HVAC CONTROLS TD-1212 is a rectangular zone damper engineered for use in forced-air zoning systems. It ships with a 60-second Belimo 3-wire actuator already mounted, allowing the blade assembly and drive mechanism to arrive as a ready-to-install unit. The damper body measures 12 inches by 12 inches at the duct opening, with an overall package footprint of 14 inches wide by 19 inches tall by 8 inches deep. Weighing 7 pounds, it is sized for residential and light-commercial duct systems. Licensed HVAC technicians performing zoned-system installations or retrofits are the primary installers of this component.

The TD-1212 is designed for rectangular zone damper applications in Trane and American Standard ducted HVAC systems. It fits into zoning configurations where individual zones require motorized airflow control, such as multi-story homes, room additions, or any installation where independent thermostat control per zone is required. The included Belimo 3-wire actuator supports spring-return or modulating-style zone control panels depending on system wiring configuration.

Key Features

• 12 inch by 12 inch rectangular duct opening for direct-fit installation
• Factory-mounted Belimo 3-wire actuator eliminates field assembly of drive components
• 60-second actuator travel time suits standard residential zone control panel timing requirements
• Overall package dimensions of 14 inches wide by 19 inches tall by 8 inches deep
• 7-pound unit weight supports standard sheet-metal duct support practices

Compatibility

Designed as a replacement or new-construction zone damper for Trane and American Standard rectangular ducted HVAC systems requiring a 12 inch by 12 inch damper with a 3-wire Belimo actuator.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with zoned forced-air systems and low-voltage control wiring. Disconnect and lock out power to the air handler and zone control panel before beginning work. Secure the damper body into the duct using standard sheet-metal screws and seal all joints per local mechanical code requirements. Verify actuator wiring matches the zone control board terminal designations before restoring power.
