The IO HVAC CONTROLS iO-FAV-08-PLUS is a fresh air ventilation control panel designed to manage outdoor air intake in forced-air HVAC systems. The panel integrates an 8-inch round 2-position damper, an onboard 120/24-volt 20VA transformer, and an outdoor temperature and humidity (ODT Humidistat) sensor into a single packaged assembly. It automates fresh air delivery based on outdoor conditions, preventing unnecessary ventilation during extreme temperatures or high humidity. Licensed HVAC technicians install this unit as part of residential or light commercial ventilation strategies, including ASHRAE 62.2-compliant mechanical fresh air systems.
This control panel suits residential forced-air systems where controlled outdoor air ventilation is required. It is particularly well suited for new construction and retrofit installations where a single enclosure managing the damper, transformer, and outdoor sensing is preferred. The included ODT Humidistat allows the system to lock out fresh air ventilation when outdoor humidity or temperature conditions would degrade indoor air quality or system efficiency. Typical installation is in a mechanical room or utility space with access to an exterior duct penetration for the 8-inch round damper connection.
Designed as an OEM-style fresh air ventilation control solution for residential and light commercial forced-air HVAC systems requiring an 8-inch round ducted outdoor air connection.
Installation should be performed by a licensed HVAC technician familiar with low-voltage controls and mechanical ventilation systems. Shut off all power to the air handler and associated circuits before wiring the control panel. Follow local mechanical codes and ASHRAE 62.2 guidelines for outdoor air duct sizing, penetration sealing, and ventilation rates. Do not operate the damper or transformer without verifying that line-voltage wiring connections are properly insulated and secured.
