Io Hvac Controls LD-2616-BM Zone Damper 26x16 Bottom Mount

Product Description

The IO HVAC CONTROLS LD-2616-BM is a 26 x 16 inch rectangular two-position zone damper designed for ducted HVAC zoning systems. It ships with a 3-wire actuator and an LED status indicator mounted at the bottom of the damper assembly. Two-position operation means the damper blade moves fully open or fully closed on command from a zone control board or thermostat, directing conditioned air to the correct zone. The bottom-mount actuator configuration simplifies installation in tight duct runs where side access is restricted. HVAC technicians and sheet metal contractors use this damper to divide a forced-air system into independently controlled comfort zones.

This damper is sized for 26 x 16 inch rectangular duct openings, making it suited for larger trunk or branch duct applications in residential and light commercial forced-air systems. It is commonly installed during new construction zoning projects or as a retrofit when upgrading a single-zone system to multi-zone control. The integrated LED provides a quick visual confirmation of damper position without requiring a multimeter, which saves diagnostic time during commissioning and service calls.

Key Features

• 26 x 16 inch rectangular damper fits standard duct openings of that size
• Two-position operation for full-open and full-closed zone control
• 3-wire actuator included, compatible with standard zone control boards
• Integrated LED status indicator for fast visual position verification
• Bottom-mount actuator placement accommodates restricted side-clearance installs

Compatibility

Designed as an OEM-style zone damper for use with 3-wire two-position zone control systems in rectangular ducted forced-air HVAC applications.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified sheet metal contractor. Shut down the air handler and de-energize the control system at the breaker before beginning installation. Secure the damper into the duct section per the manufacturer instructions and route low-voltage wiring to the zone control board following NEC low-voltage wiring guidelines. Verify LED status and damper travel during system commissioning before restoring full operation.
