Io Hvac Controls LD-1606 Zone Damper 16x6 3-wire

Product Description

The IO HVAC CONTROLS LD-1606 is a rectangular 2-position zone damper designed for duct zoning applications in forced-air HVAC systems. It ships with a 3-wire actuator and an integrated LED indicator, which allows technicians to confirm damper position at a glance without removing the unit from the duct. The damper operates in two discrete positions - fully open or fully closed - making it well-suited for zone control systems that use a central zone control board to manage airflow to individual areas. Licensed HVAC technicians are the primary installers of this component.

This damper fits 16 inch by 6 inch rectangular duct openings and is intended for residential and light commercial forced-air zoning installations. It is commonly installed on supply or return duct branches where independent zone control is required. The 3-wire actuator configuration is compatible with standard zone control panels that supply power-open and power-close signals, which is typical in multi-zone residential systems. The LED indicator simplifies commissioning and troubleshooting during startup.

Key Features

• 2-position operation - fully open or fully closed - for reliable zone isolation
• 3-wire actuator with dedicated power-open and power-close terminals
• Integrated LED indicator for visual confirmation of damper position
• Rectangular body sized for 16 inch by 6 inch duct openings
• Weighs 7 pounds for a solid, stable fit in duct installations

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for rectangular forced-air duct systems requiring a 16 inch by 6 inch damper with a 3-wire actuator interface.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with duct zoning systems. Disconnect power to the air handler and zone control panel before wiring the actuator. Follow the zone control manufacturer's wiring diagram for power-open, power-close, and common terminal assignments. Verify LED indicator function and full damper travel during system commissioning before returning the system to service.
