Io Hvac Controls D-Z1-05 Two-position Zone Damper

Product Description

The IO HVAC CONTROLS D-Z1-05 is a two-position zone damper assembly designed for use in residential and light commercial forced-air zoning systems. It controls airflow to a single zone by moving between fully open and fully closed positions, allowing the HVAC system to direct conditioned air only where it is needed. The assembly measures 5 inches in width, 5 inches in height, and 8 inches in depth, and weighs 3.74 pounds. Licensed HVAC technicians install this damper as part of a multi-zone duct system paired with a compatible zone control board and thermostat.

This damper is intended for zone one designation in ducted forced-air HVAC systems. It fits within a standard round or rectangular duct run and is actuated by the zone control panel signal. Typical installations occur in residential single-family homes and light commercial applications where independent temperature control across multiple zones is required. The two-position operation keeps the design straightforward, reducing points of failure compared to modulating dampers.

Key Features

• Two-position operation: fully open or fully closed for simple, reliable zone control
• Compact footprint at 5 x 5 x 8 inches for installation in tight duct runs
• Designated Zone 1 damper for use with compatible zoning control systems
• 3.74-pound assembly weight simplifies single-technician installation

Compatibility

Designed as an OEM-style replacement or new-installation zone damper for use in residential and light commercial forced-air zoning systems requiring a two-position, Zone 1 damper assembly.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with forced-air zoning systems. Power down the air handler and de-energize the zone control board before connecting or disconnecting damper wiring. Ensure the duct opening matches the damper dimensions before installation to avoid air bypass. Follow the zone controller manufacturer's wiring diagram and applicable local mechanical codes when integrating the damper into the zoning system.
