Malfunction code output via flash code
NOTE
If the heater is equipped with a standard timer or switch,
the error cause is outputted as a flash code via the
operating display.
Another possibility to output the flash code is via the
two-pin plug on the heater wiring harness.
After five short signals the long flash signals
are counted.
The number of long flash impulses corresponds to the
respective flash code. Flash codes and their respective
error meaning are presented in Table 502.
