10.2 Fault codes

In the event of an error message, both the 'code'-display and the t-display will flash.
For details, see Table 19.
For readout of the most recent faults, see Par. 6.9.
IMPORTANT:
Before resetting, accurately record the fault code (including figures, flashing digits and
dots) and remember to pass on this information when seeking assistance. The fault
code is important for correctly and rapidly tracing the nature of the fault.
NOTE: Shut-off mode (code b, only dots in t-display are flashing, not digits) is a
normal boiler operating function and does not represent a boiler failure. However,
this may indicate a system problem, an internal fan check or an incorrect parameter
setting.
