Table 10.3 Diagnostics codes of the second diagnostic level
1) Five-digit numbers are saved with the diagnostics codes 80 to 83. If d.80, for example, is selected, only the first two digits of the number are
displayed (e. g. 10). The display switches to the last three digits (e. g. 947) by pressing “i”. In this example the number of operating hours of the
heating is 10947 h. The display returns to the selected diagnostics item by pressing “i” again.
