IO Hvac Controls iO-FAV-04 System

The iO-FAV-04 Fresh Air Ventilation System provides precise ASHRAE 62.2 compliant ventilation for residential and light commercial applications. This comprehensive kit includes a micro-processor logic panel, a 4-inch round 2-position damper (power open/spring closed), and a 120/24V 20VA transformer. Engineered for efficiency, the system utilizes a single-adjustment timer (1-60 minutes) to manage ventilation CFM requirements ranging from 40 to 150 CFM, covering spaces up to 4,000 square feet. The logic panel features an exhaust fan control option and can be configured with outdoor temperature and humidity limits to prevent the entry of uncomfortable or unconditioned air. Designed for 24VAC power requirements, the iO-FAVPAN controller includes an override capability for manual damper operation, ensuring it meets specific IAQ (Indoor Air Quality) standards and local building codes. Its aluminum backplate construction simplifies mounting for field technicians working within tight mechanical spaces.

Common Questions

How do you adjust the intake volume on the iO-FAV-04?
The volume of fresh air is controlled by adjusting the timer dial on the iO-FAVPAN control board, which dictates the number of minutes per hour the damper remains open during the HVAC cycle.

Can this system be used with larger ducting?
The provided kit includes a 4-inch damper; however, the control logic is compatible with various damper sizes if a separate power-open spring-closed 24V actuator is utilized.

Does this system support a range of square footage?
Yes, the iO-FAV-04 is rated for coverage between 1,500 and 4,000 square feet, depending on the required air changes and duct static pressure.
