Indel Webasto Compact Classic - LED Error Reporting

8.3 LED
A 10 mA LED connected as per the electronic diagram can be used al in order to
report errors in the electronic unit: the LED ashes a number of mes equal to the
error code. Each ash lasts 1/4 of a second. A series of ashes is followed by a period
of shut-down, at the end of which the signalling cycle re-starts and repeats every 4
seconds.
It is possible to determine the type of error in the electronic unit based on the
number of ashes, as shown in the table.
