7.3 Error message
You can use the error message menu to view the most recent faults in the fault memory, in order
to investigate a fault, for example.
Faults are categorised as follows:
• current errors are all unresolved faults currently present in the system. These can be one of the
following types: locking, blocking or plant error.
• locking fault
1)
: Manually reset the heating system after the fault has been removed. For this,
press RESET on the boiler.
• blocking fault
1)
: With blocking faults, the heating system continues to operate automatically,
as soon as the fault has been removed.
• plant errors relating to the heating system are logged in the RC35. Exceptions are boiler or
burner faults that are either “locking” or “blocking” faults. The heating system keeps operating as
much as possible during the fault; a reset is not required.
