The Auroris IC-100 5V Intermittent Switch provides a versatile control solution for HRV/ERV systems, allowing users to toggle between low, high, and intermittent modes with a simple push-button interface and LED indicators. Upon initial power-up, the unit operates in low-speed mode, while pressing the button once activates high-speed mode. A second press enables intermittent mode, cycling 20 minutes of low-speed operation followed by 40 minutes off, which continues until the button is pressed again to turn the unit off. The last pressed switch determines the active mode, and flashing LEDs indicate an operational error requiring troubleshooting. Designed for easy installation, it can be mounted directly onto drywall or housed within an electrical junction box, making it an efficient and adaptable control option for residential and commercial ventilation systems.
