Io Hvac Controls LD-1412 Zone Damper 14x12 3 Wire

Product Description

The IO HVAC CONTROLS LD-1412 is a rectangular 2-position zone damper designed for use in forced-air HVAC zoning systems. It features a 3-wire actuator and an integrated LED indicator, allowing technicians to confirm damper position at a glance during installation and service. The LD-1412 measures 14 inches by 12 inches at the duct opening and weighs 7 pounds. It is installed by licensed HVAC technicians as part of a zone control system, regulating airflow to individual zones in residential or light commercial applications. The 2-position design means the damper operates fully open or fully closed, making it straightforward to wire and commission with standard zone control boards.

The LD-1412 is suited for rectangular duct systems in residential and light commercial buildings where independent zone control is required. It fits into zoning setups that divide a structure into separately conditioned areas, each controlled by its own thermostat and zone board. The integrated LED simplifies troubleshooting by providing a visible status indication directly at the damper, reducing diagnostic time during service calls. This damper is a practical fit for new zoning installations as well as retrofit projects where an existing rectangular duct run needs to be brought under zone control.

Key Features

• 14 inch by 12 inch rectangular duct opening for standard duct sizing compatibility
• 2-position operation - fully open or fully closed for straightforward zone control
• 3-wire actuator for compatibility with standard zone control panels
• Integrated LED indicator for fast visual confirmation of damper position
• Compact profile at 8 inches deep to fit in tight mechanical spaces

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for rectangular duct systems in residential and light commercial forced-air HVAC zoning applications.

Installation Notes

Installation should be performed by a qualified HVAC technician. Power down the air handler and zone control system before wiring the actuator. The damper must be mounted in a straight duct section with adequate clearance - verify depth clearance against the 8-inch profile before cutting the duct opening. Follow the zone control board manufacturer's wiring diagram for the 3-wire actuator connection, and confirm LED status after power-up to verify proper operation.
