BETA 2 Day/Night Fan 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 16ft long cable allows close placement to the plant canopy.

How it works:  

• Mount the Controller on wall, place the sensor in a well-ventilated area. 

• Connect the temperature sensor to the controller. 
• Plug the Controller into an AC wall outlet.
