Radiant REMOTO LCD Service manual

By means of the electronic printed circuit board with self-diagnostic functions, the boiler continually
checks its own operational status; should any malfunctions arise, the boiler signals the fault by
showing the relative error code on the remote control display, seen at position Ein fig. 1.
In the event of any boiler malfunctions therefore, the remote control will display the alarm codes
and the resetting procedures.
Alarms are shown with an error number (EXX, see fig.2), followed by the symbol remaining on
for alarms that can be reset, or flashing in the case of alarms which cannot be reset.
For resetting alarms, to start the boiler working again press button A which is found by opening the
right hand cover on the remote control.
