The boiler is fitted with an integrated diagnostic readout whi-
ch, in case of malfunction, consents the immediate individua-
tion of the type of fault directly from the control panel display.
In the following fault finding table our purpose is to give some
technical information regarding the solutions to any problems
which could occur during boiler operation or commissioning of
the boiler.

When the fault signalling led (1) is illuminated, press the LI-
GHT BLUE key (2) to check the error code on the display (3).
