The IO HVAC CONTROLS ld-2610 is a rectangular 2-position zone damper designed for residential HVAC zoning systems. It uses a 3-wire actuator with an LED indicator, allowing straightforward control of airflow to individual zones within a ducted forced-air system. The ld-2610 measures 26 inches x 10 inches, making it suited for larger rectangular duct runs common in residential installations. Licensed HVAC technicians install this damper as part of a zone control system, typically paired with a zone controller and individual thermostat inputs to regulate conditioned air distribution throughout the structure.
This damper is intended for residential forced-air zoning applications. It installs directly into rectangular ductwork and operates in two positions — open or closed — based on a signal from the zone control board. The 3-wire actuator connection integrates with standard residential zoning panels. The LED indicator provides a quick visual confirmation of damper position, which is useful during commissioning and troubleshooting. Typical installations include single-family homes or light commercial spaces where multiple zones require independent temperature control from a single air handler or furnace.
Designed as an OEM-style replacement or new-installation zone damper for residential rectangular duct zoning systems using 3-wire actuator control panels.
Installation should be performed by a licensed HVAC technician. Power down the air handler, furnace, and zone control panel before wiring the actuator. Secure the damper into the duct section according to the manufacturer instructions and verify the actuator wiring matches the zone controller terminal designations. After installation, cycle the system and confirm LED status and airflow response before completing commissioning.
