Io Hvac Controls SC-EB-KIT Electronic Bypass Damper Kit

Product Description

The IO HVAC CONTROLS SC-EB-KIT is an electronic bypass damper kit designed to regulate static pressure in forced-air HVAC systems. When zone dampers close and reduce airflow demand, static pressure builds in the supply duct. This kit provides an automated bypass path, diverting excess air back to the return side and protecting the blower from excessive static pressure buildup. It is installed by licensed HVAC technicians during zoning system commissioning or as a retrofit when pressure-related noise, short cycling, or equipment stress is identified.

The SC-EB-KIT is suited for residential and light commercial forced-air zoning applications. It works alongside zone control boards and motorized zone dampers to maintain balanced duct pressure as zones open and close. The kit format supplies the components needed for a complete bypass installation, making it appropriate for new zoning installations or replacements in existing multi-zone systems.

Key Features

• Electronic actuation provides automatic bypass response to changing zone demand
• Kit format includes components for a complete bypass damper installation
• Compact footprint at 5 x 5 x 10 inches supports installation in tight mechanical spaces
• Lightweight assembly at 1.75 pounds simplifies handling during overhead or in-duct installation
• Designed to reduce static pressure buildup and protect air handler blower motors in zoned systems

Compatibility

Designed as an OEM-style replacement or new-installation component for residential and light commercial forced-air zoning systems using electronic bypass pressure management.

Installation Notes

Installation should be performed by a qualified HVAC technician. Disconnect power to the air handler and zone control system before beginning any duct or wiring work. The bypass damper is typically installed in a duct bridge between the supply and return plenums, sized to match the system airflow requirements. Follow local mechanical codes and the zone control manufacturer wiring diagrams when connecting the actuator to the zone control board.
