8 ERROR CODES
8.1
BOILER PROTECTION SYSTEMS.
There are two types of errors for malfunctions:
- Shutdown (solved by resetting);
- Safety stop (No Reset: the boiler will start working again properly when the cause is removed).
There is a third type of error code that is used to indicate a malfunction that does not stop the boiler which
continues to work properly (Indication).
8.1.1

The error codes are divided in six different functional units, in other words the first figure indicates which
functional unit of the boiler is involved in the error:
