Io Hvac Controls LD-2810-BM Rectangular Zone Damper

Product Description

The IO HVAC CONTROLS LD-2810-BM is a rectangular two-position zone damper designed for duct zoning applications in forced-air HVAC systems. It features a 3-wire actuator with an integrated LED indicator, allowing technicians to confirm damper position at a glance without removing covers or running through system diagnostics. The bottom-mount actuator configuration suits installations where access from the underside of the duct is necessary. At 28 inches wide by 10 inches tall, this damper fits a standard rectangular duct opening of that size and is installed by HVAC technicians performing zone control work on residential or light commercial systems.

This damper is suited for zoning applications where a thermostat or zone controller opens and closes individual duct branches to direct conditioned air to specific zones. The two-position design means the damper blade travels fully open or fully closed in response to a zone call, making it compatible with standard zone control panels that switch 24-volt signals. The bottom-mount actuator placement makes it a practical choice in attic, crawlspace, or mechanical room installations where overhead clearance above the duct is limited.

Key Features

• 28 x 10 inch rectangular damper sized for standard rectangular ductwork
• Two-position operation: fully open or fully closed for reliable zone control
• 3-wire actuator supports standard zone control panel wiring configurations
• Integrated LED indicator confirms actuator and damper position without additional testing equipment
• Bottom-mount actuator design accommodates installations with limited clearance above the duct

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for rectangular duct zoning systems using standard 24-volt zone control panels in residential and light commercial forced-air applications.

Installation Notes

Installation is performed by a licensed HVAC technician. De-energize the zone control panel and air handler before beginning damper installation or wiring. Secure the damper into the duct opening per the manufacturer guidelines before connecting actuator wiring to the zone control panel. Verify LED indicator function and damper blade travel after restoring power to confirm proper operation.
