A potentiometer is a device to generate a control signal. Typical control signals are: 0-10 VDC, 0-20 mA or 0-100 % PWM. These infinitely variable control signals or analogue signals can be used to control an EC fan, a frequency inverter, a variable speed drive, a damper actuator, etc. In simple words, this means that they can be used to manually adjust fan speed or damper positions. Some potentiometers require a supply voltage, while other types are 'unpowered' - these types don't need a supply voltage.
