    # 3D Printer Enclosure Fan Control
    **Version: 1.0**

    The most common automation used for a Temperature Control Exhaust Fan. It really can turn anything ON and OFF on a rising & falling numeric value.

    **The Automation Process:**
     - When the sensor rises above the set value it turns the fan ON.
     - When the sensor falls below the set value it turns the fan OFF.
     - You have the option to use the "Fan Speed - Off Switch Option". This is useful for turning OFF fans with different speeds.
     - You have the option to use the "Trigger Sensor By-pass". This allows you to add a switch to manually By-pass the trigger sensor so you can use the fan as normal by turning it ON and OFF manually.
     - You have the option to set a start time, an end time and select weekdays. This will only allow the automation to run between the time periods.

     Note: If you turn the fan on manually and the automation runs it will turn the fan OFF automatically. It is recommended to use the "Trigger Sensor By-pass" option if you would like to keep the fan ON or OFF for extended time periods.
