The Day/Night Fan Controller is simple yet highly effective. It allows the fan to run at different speeds, for example 20% during the day and 60% at night, or vice versa. The built-in light sensor allows the Day/Night Fan Controller to switch from day to night mode automatically. Set the desired fan speed with the two rotary knobs.
