Io Hvac Controls LD-14 Round Zone Damper 14 in 2 Position

Product Description

The IO HVAC CONTROLS LD-14 is a 14-inch round, two-position zone damper designed for forced-air HVAC zoning systems. It ships with an integrated 3-wire actuator and an LED indicator, giving technicians a quick visual confirmation of damper position without needing to trace wiring or open the duct. The damper blade moves between fully open and fully closed, making it suited for on/off zone control rather than modulating applications. At 10 pounds, the unit is built for straightforward field installation in round ductwork by licensed HVAC technicians performing zoning upgrades or new zoning system installations.

The LD-14 is intended for residential and light commercial forced-air zoning applications where a 14-inch round duct serves a defined zone. It is typically installed in supply trunk lines or branch ducts and controlled by a compatible zoning panel or zone controller. The two-position, 3-wire wiring scheme is standard across most zone control panels, simplifying integration. The LED indicator assists during commissioning and troubleshooting, allowing the installer to confirm actuator response at the damper without a second technician at the thermostat.

Key Features

• 14-inch round duct size fits standard residential and light commercial supply ductwork
• Two-position operation provides reliable open/closed zone control
• Integrated 3-wire actuator eliminates the need for a separate motor assembly
• Onboard LED indicator confirms damper position during installation and service calls
• Self-contained unit reduces parts count and simplifies commissioning

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for 14-inch round duct zoning systems controlled by standard 3-wire zone control panels.

Installation Notes

Installation should be performed by a licensed HVAC technician following applicable mechanical codes. Power down the zoning panel and air handler before wiring or mounting the damper. The damper should be positioned in an accessible section of ductwork to allow future servicing of the actuator and LED. Verify correct wire terminations at the zone panel before restoring power and testing damper travel.
