11.1.2 Checking the fans
If necessary, there are two different ways to check the fans are functional:
•
Set the "Fan Test" parameter to "1" in the installer mode (using Sunny Data, Sunny
Data Control, the Sunny Boy Control data logger or the Sunny WebBox).
•
Place the jumper on the controller board (the jumper required to check the fans is
included in the Sunny Mini Central accessories kit).
Check the fans as follows:
Step
Instructions
Setting the Parameter
1
Ask for the Installer Password from the SMA Hotline (for contact information
see page 103).
2
Set the „Fan Test" parameter in the installer mode to „1" (using Sunny Data,
Sunny Data Control, the Sunny Boy Control data logger or the Sunny Web-
Box).
3
Check the fans' air-flow. The Sunny Mini Central 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.
4
Set the „Fan Test" parameter back to „0" when you have finished checking
the fans.
