1) In the diagnosis codes 80 to 83 5 digit figure values are stored. When selecting e.g. d.80 only the first two digits of the figure value
are displayed (e.g.10). By pressing the "i“ key, the display switches over to the last three figures (e.g. 947). The operating hours
counter of the heating in this case would be 10947 h. Pressing the "i" again causes the display to switch back to the diagnosis point
that was called up.
Table 9.3 Diagnosis codes at diagnosis level 2 (continued)
9.1.3 Fault
codes
The fault codes displace all other displays when errors
occur. Errors are displayed as "F ...", e.g. "F.10"
(see Table 9.4).
If several errors occur simultaneously, each fault code is
displayed for approximately two seconds on an
alternating basis.
Once you have repaired the error push the fault
clearance key to restart the boiler.
If the error cannot be repaired and reoccurs despite
having carried out several fault clearance attempts,
please contact your factory customer service.
9.1.4 Fault
memory
The last ten errors which occurred are saved in the
appliance fault memory.
• Push the "i“ and „-“ buttons simultaneously.
• Scroll back in the error memory with the "+" button.
You can exit the fault memory display as follows:
• Push the "i" button
or
• Do not push any buttons for about 4 minutes.
Depending on the settings, the current flow temperature
or current filling pressure of the heating installation
reappears in the display.
