Io Hvac Controls hd-1816-po Zone Damper 18x16 Powered Open

Product Description

The IO HVAC CONTROLS hd-1816-po is an 18 x 16 inch rectangular, two-position zone damper designed for powered-open operation in residential forced-air HVAC systems. Zone dampers control airflow to individual zones within a ducted system, allowing each area of a building to be conditioned independently. This damper opens when power is applied and returns to the closed position when de-energized, making it suitable for use with standard residential zone control panels. HVAC technicians install this damper directly into rectangular ductwork as part of a zoning system build-out or retrofit.

This damper is intended for residential zoning applications in ducted forced-air heating and cooling systems. It fits into rectangular duct runs measuring 18 x 16 inches and works alongside zone control boards, thermostats, and bypass dampers to balance airflow across multiple zones. Its powered-open, spring-return design ensures the damper defaults to closed when power is removed, which is a common fail-safe configuration for residential zoning systems.

Key Features

• Powered-open, spring-return two-position operation for reliable fail-safe closure
• Rectangular form factor sized at 18 x 16 inches for direct duct installation
• Designed for residential forced-air zoning systems
• Two-position control simplifies integration with standard zone control panels

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for residential rectangular ductwork measuring 18 x 16 inches in forced-air zoning systems.

Installation Notes

Zone dampers are installed by licensed HVAC technicians as part of a ducted zoning system. Power down the air handler and zone control panel before wiring or repositioning any damper. Follow the zone controller manufacturer's wiring diagram and reference applicable mechanical and electrical codes during installation. Do not apply power to the actuator outside of its rated voltage range as specified by the zone control system.
