Drive the External Fan

There are three different ways to drive the external Fan:
1
2
3
378/406
Add to the connection cable the proper exten-sion cable (models:
969-6514, 969-6515, 969-6516, 969-6517) needed to reach the
control-ler. Insert the plug in the connection P2 on the rack
controller rear panel.
Start the FAN as explained in the following section: "Drive the
external fan".
Always ON
Set the serial command WIN 143 = 0 (value in WIN = 144 is not
considered)
Automatic (the external fan is always ON during the Ramp status
and On Command when the pump reaches the target speed. That
means that WIN 144 determines the Fan status when the pump
reaches the "normal" status)
Set WIN 143 = 1, WIN 144 = 1 (external fan ON) or WIN 144 = 0
(external fan OFF)
Serial (the fan behaviour depends only on WIN 144 value)
Set WIN 143 = 2, WIN 144 = 1 (external fan ON) or WIN 144 = 0
(external fan OFF)
