6.4 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).
The Shutdown and the Safety stop are alternatively signalled with the respective error code and the writing
"Err."
6.4.1 Error codes

functional unit of the boiler is involved in the error:
1. Primary circuit;
