The TrolMaster BETA-2 Fan Speed Controller 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 an economical and efficient way of dealing with heat within an enclosed space.
Note: Shipping is a Flat $40 for All ThinkGrow/TrolMaster Orders
