Io Hvac Controls HD-2810 Zone Damper 28x10 2 Wire

Product Description

The IO HVAC CONTROLS HD-2810 is a rectangular two-position zone damper with a 2-wire actuator, designed for use in residential and light commercial HVAC zoning systems. Sized at 28 inches by 10 inches, it controls airflow to individual zones by opening or closing on command from a zone control panel. The 2-wire actuator simplifies wiring runs and reduces installation time compared to multi-wire configurations. At 10.35 pounds, the HD-2810 is a solid, duct-ready component suited for forced-air systems where precise zone control is required. HVAC technicians and sheet metal contractors are the primary installers of this damper type.

The HD-2810 is intended for rectangular ductwork applications in ducted forced-air heating and cooling systems. Its two-position operation - fully open or fully closed - makes it appropriate for standard on/off zone control setups rather than modulating airflow applications. Typical installations include residential multi-zone systems and light commercial VAV-style zoning where individual rooms or areas require independent temperature management. The damper fits into existing rectangular duct runs during new construction or retrofit projects.

Key Features

• 28 inch by 10 inch rectangular damper blade sized for standard duct openings
• Two-position operation provides fully open or fully closed airflow control
• 2-wire actuator reduces low-voltage wiring complexity
• Packaged dimensions of 33 inches wide by 6.7 inches high by 13 inches deep for shipping and storage planning
• 10.35 pound construction supports durable, long-term duct installation

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for rectangular ducted forced-air HVAC zoning systems using two-position, 2-wire actuator control panels.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with forced-air zoning systems and low-voltage control wiring. Power down the air handler and de-energize the zone control panel before beginning damper installation or wiring connections. The damper must be mounted inline with existing rectangular ductwork, ensuring proper airflow direction alignment with the blade orientation. Follow all applicable local mechanical codes and manufacturer zone panel wiring diagrams when making low-voltage actuator connections.
