Malfunction, errors to be reset by user and self-resettable faults
The display indicates the fault through the relevant error code (see following table). Some
faults can be reset by pressing the "reset" key (r), some others are self-resettable (a) and
reset only when the fault is resolved:
Boiler shut-down due to missing flame
(r)
Boiler shut-down due to double flow probe triggering
(r)
Boiler shut-down due to air pressure switch triggering
(r)
Boiler shut-down due to too low system pressure
(a)
Boiler shut-down due to double flow probe fault
(a)
Warning: in case of self-resettable faults, only
back-lighting of the LCD will remain active while
the relevant error code will flash. In case of
resettable faults, instead, the error is displayed
in a steady way, and the "reset" key is enabled
as well to reset boiler shut-down condition.
In either case, once the fault has been resolved,
back-lighting of all keys is enabled and after
one minute (no other key being pressed) the
interface is disabled.
