These are temporary alarms that if they occur 6 times in an hour they become definitive; the alarm E097 is displayed
and is followed by post-purging for 45 seconds at the fan's maximum speed.
It is not possible to release the alarm before the end of the post-purging unless the boiler's power supply is switched
off.

incomplete combustion
These are temporary alarms that if they occur several
times in an hour they become definitive; the last error to occur
is displayed and is followed by a post-purging of 5 minutes at the fan's maximum speed.
It is not possible to release the alarm before the end of the post-purging unless the boiler's power supply is switched
off.

Red
flue gases obstruction alarm
Temporary fault signalled during Pre-Purging. Post-Purging is maintained for 5 min at maximum fan speed.
5.16 Error history
The
ERROR HISTORY
function is automatically enabled only after the machine has been
powered up for at least 2 consecutive hours, during this period of time any alarms that arise
would not be saved in the “error history
”. The alarms can be displayed in chronological order,
from the most recent to the oldest, up to a maximum of 50 alarms; to display the
error history:
-
access the technical parameters as explained in the section“ Accessing the technical
parameters”
- select
ERROR HISTORY
with the "UP" and "DOWN
" keys, confirming the selection

INSTALLER
- scroll through the alarms log with the “UP” and “DOWN

USE ARROW KEYS TO SEE OTHER ANOMALIES
It is possible to return to the start page at any time by keeping the
“BACK”

for at least 2 seconds.
Note:
Once enabled, the ERROR HISTORY
function can no longer be disabled; there is no
procedure for resetting the error history.
If an alarm repeats consecutively, it is saved only once.
The alarms log contains both boiler alarms as well as alarms regarding the heat pump.
5.17 Temporary switch-off
In the event of temporary absences (weekends, short breaks, etc.) set the status of the
boiler to OFF
.

HEATING AND HOT WATER
BOILER
While the electrical supply and the fuel supply remain active, the boiler is protected by the
systems:
-
heating anti-freeze:
this function is activated if the temperature measured by the flow
sensor drops below 5°C. A heat request is generated in this phase with the ignition of the
burner at minimum output, which is maintained until the outlet water temperature reaches
35° C;
