Overview
Thank you for purchasing the TrolMaster BETA-2 Fan Speed Controller. The BETA-2 is a simple and affordable way to
control your fan. Choose your desired fan speed and tempeature 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 termperature sensor
with 16ft long cable allows close placement to the plant canopy.
