Io Hvac Controls HD-1608-BM Rectangular Zone Damper

Product Description

The IO HVAC CONTROLS HD-1608-BM is a rectangular two-position zone damper designed for ducted HVAC zoning systems. It accepts a 2-wire actuator and ships with a bottom-mount configuration, making it suited for installations where top or side access is restricted. The damper measures 16 inches wide by 8 inches in duct opening size and fits within a housing footprint of 14 inches wide by 20 inches tall by 8 inches deep. At 8 pounds, it is a solid assembly intended for permanent duct installation. Two-position operation means the damper moves fully open or fully closed on a call, which is standard for residential and light commercial zone control applications.

This damper is used in forced-air zoning systems where individual zones require independent airflow control. Typical installations include residential split systems and air handlers with multi-zone thermostat controllers. The bottom-mount actuator position suits horizontal duct runs where vertical access from above is not available. HVAC technicians installing or retrofitting zone control panels will find this a direct-fit duct-mounted component for rectangular duct applications.

Key Features

• Two-position operation: fully open or fully closed for zone control
• 2-wire actuator wiring simplifies connection to zone control boards
• Bottom-mount actuator orientation for horizontal duct run installations
• Rectangular 16-inch by 8-inch duct opening size
• Housing dimensions of 14 inches wide by 20 inches tall by 8 inches deep
• 8-pound assembly weight indicating robust construction

Compatibility

Designed as an OEM-style replacement or new-install zone damper for rectangular ducted residential and light commercial forced-air HVAC zoning systems using two-position, 2-wire zone control wiring.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with zoned forced-air systems. Power down the air handler and zone control panel before connecting or disconnecting the actuator wiring. The damper must be mounted in the duct with the actuator positioned at the bottom as designed; do not reposition the actuator housing. Follow the zone controller manufacturer's wiring diagram for 2-wire actuator connections and verify proper open and closed travel before restoring system power.
