Drive the External Fan
There are three different ways to drive the external Fan:
1
Always ON
Setting WIN 143 = 0 the fan remains always ON (the value in
WIN144 is not considered)
2
Automatic Setting WIN 143 = 1 the external fan is always ON
during the Ramp-up status. In the others status the fan behavior
depends only on WIN 144 value: WIN 144 = 1 external fan ON;
WIN 144 = 0 external fan OFF That means that WIN 144
determines the Fan status when the pump reaches the “normal”
status.
3
Serial With WIN 144 = 2 (default value) the external fan is
configured in serial mode, in this condition the fan behavior
depends only on WIN 144 value) Setting WIN 143 = 2: WIN 144 =
1 external fan ON; WIN 144 = 0 external fan OFF. The WIN 143
default value is 0.
