Io Hvac Controls ld-1608 Zone Damper 16x8 in 2 Position

Product Description

The IO HVAC CONTROLS ld-1608 is a two-position rectangular zone damper designed for residential forced-air HVAC zoning systems. It measures 16 inches by 8 inches and is equipped with a three-wire actuator and an integrated LED indicator. The damper operates in two positions — fully open or fully closed — to direct conditioned air to specific zones on demand. Licensed HVAC technicians install this type of damper as part of a multi-zone duct system controlled by a zone control board and individual thermostats. The LED indicator provides a quick visual confirmation of damper position during commissioning and service calls.

The ld-1608 is suited for residential zoning applications where rectangular duct runs require automated airflow control. It fits inline within a rectangular duct section and is actuated by low-voltage control signals from a compatible zone control panel. Typical installations include split systems, air handlers, and furnace-based forced-air systems serving multiple zones. This damper is appropriate for new construction and retrofit zoning projects where duct geometry matches its 16 inch by 8 inch rectangular profile.

Key Features

• Two-position operation — fully open or fully closed for precise zone airflow control
• Three-wire actuator for direct connection to standard zone control panels
• Integrated LED indicator for fast visual status confirmation during service
• Rectangular shape fits standard 16 inch by 8 inch duct openings
• Designed for residential forced-air zoning applications

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for residential rectangular duct systems requiring two-position, low-voltage actuated airflow control.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with low-voltage zoning controls and duct fabrication. Power down the air handler or furnace and de-energize the zone control panel before wiring the actuator. The damper must be mounted inline within the duct with proper support to prevent stress on the actuator assembly. Refer to the zone control manufacturer wiring diagram for correct three-wire terminal assignments before energizing the system.
