Note:
• Only one of the following control possibilities (A, B, C, D) can be used at the same time.
• The potentiometer must be disconnected if the fan should be controlled by other accessories.
• The fan will stop if imposed signals are lower than 2 V DC, 4 mA or 10 %.

The motor speed can be set via the duty
cycle. When the duty cycle is changed
from 10 to 95% the motor changes
speed from 0% to 100% of the maximal
speed.
