FAULT FINDING
The TURBOmax Plus and
THERMOcompact boilers have an
inbuilt advanced multifunction
diagnostic display to assist with fault
finding in the unlikely event of a
boiler malfunction.
The display features the following four
modes:
Normal Mode
Under normal conditions the boiler
display will show the boiler flow
temperature, this indicates that the
boiler is operating correctly after an
internal self check.
Status Mode
The status display is helpful in
diagnosing faults where a fault code
is not displayed.
Diagnostic Mode
In order to assist with the pinpointing
of a particular fault it is possible to
use the boiler display in a diagnostic
mode to interrogate the boiler about
the status of certain components.
Fault Mode
Should a fault develop in the boiler
the display will show a fault code
indicating what the problem may be.
