Io Hvac Controls SC-ZD-0808 Modulating Zone Damper 8x8

Product Description

The IO HVAC CONTROLS SC-ZD-0808 is a modulating zone damper designed for commercial HVAC zoning applications. It controls airflow within a duct system by adjusting blade position across a continuous range of travel, allowing precise delivery of conditioned air to individual zones. With an 8 x 8 inch duct opening, this damper fits standard commercial rectangular duct sections. Installation is typically performed by licensed HVAC technicians as part of a multi-zone variable air volume or zoning control system. The unit weighs 6 pounds and has overall package dimensions of 11 x 19 x 9 inches.

This damper is suited for commercial zoning systems where modulating control is required rather than simple open/close operation. Typical installations include multi-zone rooftop unit systems, commercial split systems, and fan coil applications where a zone controller or building automation system drives damper position via a control signal. It is not intended for residential single-zone systems requiring only two-position actuation.

Key Features

• Modulating operation allows continuous blade positioning for precise airflow control
• 8 x 8 inch duct opening fits standard commercial rectangular duct sections
• Commercial-grade construction suitable for multi-zone HVAC systems
• Compact assembled footprint of 11 x 19 x 9 inches for easier duct integration
• 6 pound unit weight supports straightforward handling and duct mounting

Compatibility

Designed as an OEM-style modulating zone damper for commercial rectangular duct systems requiring 8 x 8 inch opening damper control.

Installation Notes

Installation should be performed by a licensed HVAC technician familiar with commercial zoning systems. De-energize the air handling unit and disconnect all control wiring at the zone controller before beginning work. Verify that the control signal type and voltage from the zone controller are compatible with the damper actuator before wiring. Follow applicable mechanical and electrical codes, including SMACNA duct installation standards and NEC low-voltage wiring requirements, during installation.
