7.3 Error message
The most recent fault from the fault memory can be displayed using the error message
(e.g. to investigate a fault).
The faults are divided into the following categories:
• Current faults are all unresolved faults currently present in the system. These can be one of the
following types: locking, blocking or system error.
• Locking faults: When the fault is remedied, the heating system needs to be unlocked manually.
To do so, press the Reset button on the boiler.
• Blocking type faults: With blocking faults, the heating system resumes operation automatically as
soon as the fault has been rectified.
• System faults in the heating system are logged in the RC35, with the exception of faults in the
boiler or the burner, which are either “locking” faults or “blocking” faults errors. The heating
system continues to run – where possible – during the fault state; no reset is necessary.
