Io Hvac Controls hd-2216-bm Zone Damper 22x16 in Bottom Mount

Product Description

The IO HVAC CONTROLS hd-2216-bm is a rectangular two-position zone damper designed for residential HVAC zoning systems. Measuring 22 inches by 16 inches, this damper uses a 2-wire actuator and features a bottom-mount configuration. Zone dampers like this one regulate airflow to individual zones within a ducted forced-air system, opening and closing in response to a zone controller or thermostat call. Licensed HVAC technicians typically install and commission this type of damper as part of a complete zoning system.

This damper is suited for residential ducted HVAC applications where zoning is used to control comfort in separate areas of a home. The 22-inch by 16-inch rectangular profile fits standard rectangular duct runs of that cross-section. The two-position design means the actuator drives the blade fully open or fully closed, making it appropriate for on/off zone control rather than modulating airflow. It is commonly installed in supply or return trunk lines serving individual zones.

Key Features

• 22 inches by 16 inches rectangular profile fits standard duct openings of that size
• Two-position operation opens and closes fully for reliable on/off zone control
• 2-wire actuator simplifies low-voltage wiring connections to a zone control board
• Bottom-mount actuator configuration suits installations where side or top access is limited
• Designed for residential HVAC zoning to balance comfort across multiple areas

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for residential rectangular duct zoning systems requiring a 22-inch by 16-inch two-position damper with a bottom-mount 2-wire actuator.

Installation Notes

Installation should be performed by a licensed HVAC technician. Power down the air handler and zone control board before making any wiring connections. The damper must be mounted so the actuator is accessible for service and the blade orientation aligns with the intended airflow direction. Follow the zone controller manufacturer's low-voltage wiring diagram for proper 2-wire actuator hookup.
