The BETA-2 can control variable-speed fans by using the current temperature to increase or decrease the fan speed. By increasing the fan speed, cooling is increased… decreasing fan speed will reduce cooling capacity. Using the BETA-2 in this way provides a VERY economical and efficient way of dealing with heat within an enclosed space.
