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

    TrolMaster Digital Day/Night Fans Speed Controller

    The BETA-2 is a simple and affordable way to control your fan. Choose your desired fan speed and temperature setpoint, when the temperature is lower than the setpoint, the controller will automatically maintain that specified fan speed. When the temperature is higher than the setpoint, the controller will output 100% power to the fan. When the temperature is lower than the cut-off setpoint, the controller will shut down the fan. A built-in photocell located on the controller automatically detects the day and night status, controlling the fan in day/night mode separately. A remote temperature sensor with a 16ft long cable allows close placement to the plant canopy.
