Functions
Fan speed adjustment is achieved by changing the wiper position on the potentiometers. A potentiometer output
becomes active when mains live is applied to the corresponding input terminal.
Note:
the potentiometer range of adjustment is between 0 and 10 KΩ. When more than one fan is connected to
the control signal output there will be some loss of linearity and resolution at the higher speed settings according
to the control response graphs below.
