Boiler Protection Devices; Safety Shut-Off; Shutdown - Ariston GENUS PREMIUM EVO HP 45 Design, Installation And Servicing Instructions

The boiler is protected from malfunctions by means of internal
checks performed by the electronic P.C.B., which stops the boiler
from operating if necessary. In the event of the boiler being shut off
in this manner, a code appears on the control panel display which
refers to the type of shut-off and the reason behind it.
Two types of shut-off may occur:

Safety shut-off

This type of error is "volatile", which means that the boiler starts up
again automatically as soon as the problem which caused the shut-
off is removed.
The display will visualise the error code and description.
"Fault 110 - Send Probe Damaged"
In fact, soon as the cause of the shut-off disappears, the boiler
starts up again and continues to operate normally.
If the boiler still indicates a safety shut-off , switch it off . Make sure
the external electric switch is in the OFF position, shut off the gas
valve and contact a qualifi ed technician.
ALERT
Call the technical service
Safety shut-off due to insuffi cient water pressure
If the water pressure inside the heating circuit is insuffi cient, the
boiler will perform a safety shut-off .
The error code "Fault 108 - Filling Needed" appears on the display
The system may be restarted, re-balancing the value, by using the
fi lling valve.
ALERT
Check the pressure on the pressure gauge and close the valve as
soon as it reaches 1 - 1.5 bar.
If the re-balancing request is performed on a frequent basis, switch
the boiler off , bring the external electric switch to the OFF position,
shut off the gas valve and contact a qualifi ed technician to check
for any leaks of water.
Operation shutdown
This type of error is "non-volatile", which means that it is not
removed automatically.
The display will visualise the error code and description.
"Fault 501 - No fl ame detected - Press the Reset button"
In this case the boiler does not restart automatically, but it may be
reset by pressing the

Important
If this shutdown occurs frequently, contact an authorised Technical Service
Centre for assistance. For safety reasons, the boiler will permit a maximum of 5
resets in 15 minutes (5 presses of the RESET button); at the 6th attempt within
this 15-minute period the boiler will shut down and may only be operated
again after the electricity supply has been disconnected. If the shutdown is
occasional or an isolated event, this is not a problem.
The fi rst fi gure of the error code (e.g. Errore 101) indicates within
which operational assembly the error occurred.
1 - Primary Circuit
2 - Domestic Hot Water Circuit
3 - Internal Electronic Part
4 - External Electronic Part
5 - Ignition and Detection
6 - Air inlet - fl ue gas outlet
7 - Multizone
Malfunction warning
This warning is shown by the display in the following format:
Warning 5P1 = 1st Ignit Failed Warning 5P1
the fi rst fi gure indicating the operational assembly is followed by a P
(warning) and the code relating to the specifi c warning.
