Io Hvac Controls LD-2016 Rectangular Zone Damper 20x16

Product Description

The IO HVAC CONTROLS LD-2016 is a rectangular two-position zone damper designed for use in ducted HVAC zoning systems. It features a 3-wire actuator and an integrated LED indicator, allowing technicians to confirm damper position at a glance during commissioning and service calls. At 20 inches by 16 inches, this damper fits standard rectangular duct sizes common in residential and light commercial applications. It is installed by licensed HVAC technicians as part of a multi-zone forced-air system to control conditioned airflow to individual zones.

This damper is suited for residential and light commercial zoning installations where rectangular ductwork is used. The two-position design opens and closes fully in response to a zone controller or thermostat signal, making it a straightforward choice for new installations and retrofit zoning projects. The 3-wire actuator wiring scheme is compatible with most standard zone control boards, simplifying integration into existing or new control systems.
