8.1.3 Fault codes

Fault codes take priority over all other display functions
in the event of a system fault occurring (Table 8.3).
If multiple faults occur, the corresponding fault codes
are displayed alternately for about two seconds each.

8.1.4 Fault memory

The fault memory stores details of the ten most recent
faults.
• Press the ”i” and ”–” buttons simultaneously.
• Use the ”+” button to scroll back through the list of

memorised errors.

To cancel fault error memory display mode, proceed as
follows:
• Press the ”i” button below the display or
• Do not touch any key for about four minutes. The dis-

play will now revert back to showing the current flow
temperature.
