The fan controller has two modes of operation.
1. Automatic operation
For this the PWM signal of the MB is used and the speed of all fans
connected (PWM and 3-pin) can be adjusted automatically through
the MB.
In this mode the fan controller slider switch must be set to the first
position "0" on the far left.
2. Manual control
When the fan controller slider switch is moved from its first
position "0" to the right, the PWM signal is dropped and the fan
speed can be regulated manually.
