Five-digit numbers are saved for diagnostics codes 80 to 83. If you select D.80, for example, only the first two digits of the number
will be displayed (e.g. 10). Pressing
switches the display to the last three digits (e.g. 947). In this example, the number of oper-
ating hours for the heating is 10947 hrs. Pressing the
again causes the display to switch back to the diagnostics code that was
called up.
