11.1.2 Lock out
If the blocking conditions still exist after various start attempts, the boiler
goes into lockout (also called error). The boiler will also lock out if an error
is signalled anywhere in the boiler. An error code will appear on the dis­
play. The error code is displayed as follows:
In a red flashing display:
the symbol
the symbol
the error code, for example
The meaning of the error codes can be found in the error table. Note the
error code.
Note
The error code is needed to find the cause of the error quickly and
correctly and for any support from Remeha.
