12 Fault
finding
The IFA router is a quality product and is designed for many years of continuous use. Should, however,
a fault occur, the cause of the fault is often not the IFA router itself but the peripheral system compo-
nents. The following description of some causes of problems should help the installer and operator to
isolate the problem so that the system can be repaired as quickly as possible and to avoid unnecessary
costs. Of course, not all possible problems can be listed here. Here you will find the most common
causes of problems that cover the majority of possible faults. Only return the IFA router when you are
absolutely sure that none of the problems listed below is responsible for the fault.

and the specific firmware of the solar thermal controller
(displayed in Off mode, see the solar controller operating
instructions).
The logo is not displayed.
The logo must have the name "Logo.jpg" and must be cre-
ated in the JPEG format. It must be located on the USB flash

"Note: Maintenance work on the IFA
router ... please wait..." or "Note: File
system check ... please wait..."
The IFA router is independently conducting data cleanup/
maintenance work! This message usually appears daily
between 00:00 and 00:15 hours, and automatically disap-
pears again. On no account should you pull the plug! If the
message appears outside of this time period, an error has
occurred. If this is the case, re-start the device!
