8.2 Checking the fans
If necessary, there are three different ways to check the fans are functional:
• Set the "Fan Test“ parameter to "1“ (using Sunny Data, Sunny Data Control or
the Sunny Boy Control data logger).
• Set the jumper on the controller board.
Proceed as follows to set the jumper to check the fan.
1. Open the Windy Boy 5000 / 6000 as described in section 6.1 "Opening the
Windy Boy” (page 35).
2. Connect the enclosed jumper to the slot shown below on the controller board.
3. Close the Sunny Boy 3800 again and restart it. Follow the instructions in chapter
6.2 "Closing the Windy Boy” (page 35).
4. Once you have put the jumper in position, you must restart the Sunny Boy 3800.
Check the fan's air-flow; the Sunny Boy 3800 sucks air in from underneath and
then blows it back out on the upper sides. Look out for any unusual noise which
could indicate incorrect installation or that the fans are faulty.
5. Once you have checked the fans, you must set the "Fan Test" parameter back to
0 and remove the jumper.
The Sunny Boy 3800 recognizes the jumper only once the system has been
restarted.
