Io Hvac Controls TD-2010 Rectangular Zone Damper 20x10

Product Description

The IO HVAC CONTROLS TD-2010 is a rectangular zone damper designed for use in residential and light commercial HVAC zoning systems. Built for Trane and American Standard duct configurations, this damper controls airflow through a 20 x 10 inch duct opening using a 60-second Belimo 3-wire actuator. The 3-wire actuator provides reliable open, close, and spring-return control, making it well-suited for zone control boards that require powered open and powered close or spring-return operation. HVAC technicians install this damper as part of a multi-zone forced-air system to balance conditioned air delivery across different areas of a structure.

This damper is intended for rectangular duct applications matching Trane and American Standard system configurations with a 20 x 10 inch duct size. It fits into zoning setups where precise airflow control is needed per zone, such as two-story homes, additions, or commercial suites served by a single air handler. The 60-second actuator timing is compatible with most residential zone control boards that accept standard 3-wire Belimo-type actuator wiring. Installation is typically performed by a licensed HVAC technician as part of a complete zoning system retrofit or new installation.

Installation Notes

Installation should be performed by a licensed HVAC technician. Disconnect power to the air handler and zone control board before installing or wiring the damper actuator. Verify the zone control board supports a 3-wire Belimo-type actuator signal before connecting. Follow local mechanical codes and the zone control system manufacturer wiring diagram for proper actuator hookup.
