18 Error indication
A detected error is indicated on the display by means of a blocking or error messages.
A distinction should be made between these two messages due to the fact that blocking
can be of a temporary nature, however, error messages are fixed lockings. The control
will try its utmost to prevent locking and will temporarily switch off the boiler by blocking
it. Below is a list of some of the messages.
Blocks
with a number in the last 2 positions.
Block 60:
