Io Hvac Controls TD-10 Round Zone Damper 10 Inches

Product Description

The IO HVAC CONTROLS TD-10 is a 10-inch round zone damper designed for use in ducted HVAC zoning systems. It ships with a 60-second, 3-wire, 24-volt AC Belimo-compatible actuator pre-mounted to the damper body, making it a ready-to-install assembly for residential and light commercial zoning applications. The 3-wire actuator configuration supports spring-return operation, providing a fail-safe open or fail-safe closed position when power is removed. Licensed HVAC technicians install this damper as part of a multi-zone control system to regulate airflow to individual conditioned spaces.

This damper assembly is suited for round duct runs in forced-air zoning setups where independent temperature control is required across multiple zones. It is compatible with Trane AS zone control systems, making it a direct-fit option for contractors working on Trane zoning installations. The 10-inch duct diameter fits common trunk and branch duct configurations in residential new construction and retrofit projects. The 24-volt AC control voltage aligns with standard low-voltage thermostat and zone control board wiring.

Key Features

• 10-inch round damper sized for standard residential and light commercial ductwork
• Integrated 60-second, 3-wire, 24-volt AC actuator included as a complete assembly
• Belimo-compatible actuator design for broad zone controller support
• Spring-return operation provides fail-safe positioning on power loss
• Compatible with Trane AS zone control systems
• Low-voltage 24-volt AC control simplifies integration with existing zone boards

Compatibility

Compatible with Trane AS zone control systems. The TD-10 is designed as an OEM-style replacement or new-installation zone damper for 10-inch round duct applications in 24-volt AC forced-air zoning systems.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with low-voltage zone control wiring and duct fabrication. Power down the air handler and zone control board before making any electrical connections. The damper should be installed in an accessible section of ductwork to allow actuator service and inspection. Refer to the zone controller manufacturer wiring diagram for proper 3-wire actuator terminal assignments.
