Io Hvac Controls HD-2016-BM Zone Damper 20x16 Rectangular

Product Description

The IO HVAC CONTROLS HD-2016-BM is a two-position rectangular zone damper designed for ducted HVAC zoning systems. Sized at 20 inches by 16 inches, it controls airflow to individual zones by moving between fully open and fully closed positions. The 2-wire actuator simplifies wiring to zone control boards and thermostats. At 11 pounds, the HD-2016-BM is a robust assembly suited for light commercial and residential forced-air applications. The bottom-mount actuator configuration provides clearance in tight duct chases and is installed by licensed HVAC technicians during system commissioning or retrofit zoning upgrades.

This damper is used in residential and light commercial forced-air zoning applications where independent temperature control is required in multiple areas of a building. It mounts inline with rectangular ductwork in new construction and retrofit installations. The two-position operation makes it compatible with standard zone control panels that switch the actuator between open and closed states. Typical applications include multi-zone split systems, air handler-based zoning setups, and bypass damper configurations managed by a central zone controller.

Key Features

• Two-position operation - fully open or fully closed for straightforward zone control
• 2-wire actuator reduces wiring complexity at the zone control panel
• Bottom-mount actuator placement suits tight duct chases and overhead installations
• Rectangular 20 x 16 inch frame fits standard duct openings of that size
• Sturdy construction at 11 pounds for reliable long-term operation in ducted systems

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for rectangular ducted forced-air HVAC zoning systems requiring a 20 x 16 inch two-position damper with a 2-wire actuator.

Installation Notes

Installation should be performed by a licensed HVAC technician. Shut down the air handler and disconnect power to the zone control system before beginning work. The damper mounts inline in rectangular ductwork and should be secured with sheet metal screws and sealed with approved foil tape or mastic per local mechanical codes. Verify actuator wiring polarity and connection at the zone control board before restoring power.
