Control signal terminals 3 (DI2) and 4 (DI3) are connected 
with a jumper.
A fan is used to supply and remove air, with the specific 
action depending on the operating direction being used.
In one of these operating modes (e.g., supplying air, FWD 
via DI1), the fan speed can be variably adjusted by using 
the internal setpoint potentiometer .
In the other (removing air, REV via DI2 and DI3), the fan is 
run with the speed configured as a set value in parameter 
P-20 (default setting = 15 Hz).
