Feature: 1. Backlight LCD screen displays working time and 0-100% speed percentage. 2. Can set slow run/stop time and automatic run/stop times. 3. The upper limit and lower limit of the speed can be set, change the speed by buttons rather than the potentiometers that is easy to damage. 4. Can set the total working time, the motor stops when the time is up. 5. Can set run time and stop time, repeatedly and automatically cycle run and stop.
