Io Hvac Controls TD-2016 Rectangular Zone Damper 20x16

Product Description

The IO HVAC CONTROLS TD-2016 is a rectangular zone damper engineered for use in residential and light commercial HVAC zoning systems. It controls airflow through individual zones by opening and closing on command from a zone control board, allowing independent temperature management in each area of a structure. The damper ships with a Belimo 3-wire actuator that completes a full open or close cycle in 60 seconds. The 3-wire configuration provides both open and close power signals for positive positioning in either direction. Licensed HVAC technicians install this damper as part of a ducted forced-air zoning system.

This damper is sized for a 20 x 16 inch duct opening and is designed to replace Trane and American Standard rectangular zone dampers in existing zoning installations. It fits into standard rectangular supply or return trunk branches where zoning control is being added or where an original damper has failed. The 60-second Belimo actuator cycle time is compatible with typical residential zone control board timing requirements, making it a direct-fit replacement in those systems without requiring controller reprogramming in most cases.

Key Features

• 20 x 16 inch nominal duct size for rectangular duct applications
• Belimo 3-wire actuator provides positive open and close control signals
• 60-second actuator cycle time suits standard residential zone control board timing
• Designed as a replacement for Trane and American Standard rectangular zone dampers
• Package weight of 11 pounds reflects a robust actuator and damper blade assembly

Compatibility

Designed as a replacement for Trane and American Standard rectangular zone dampers in ducted forced-air zoning systems using a 20 x 16 inch duct opening.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with low-voltage zoning controls. Disconnect power to the air handler and zone control board before mounting the damper or making any wiring connections. The Belimo 3-wire actuator must be wired according to the zone control board manufacturer wiring diagram for open, close, and common terminals. Verify damper blade rotation and end-stop positions after power-up to confirm proper operation before closing up ductwork.
