boiler protection devices
Appliance shut-o ff conditions
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 o ff
in this manner, a code appears on the control panel display which
refers to the type of shut-o ff and the reason behind it.
Two types of shut-o ff may occur:
Safety shut-o ff
This type of error is “volatile”, which
means that the boiler starts up again
automatically as soon as the problem
which caused the shut-o ff is removed. On
the display fl ash “Err” and the error code
(es.
Err/110
)
and appear the symbol
- see the error table .
In fact, soon as the cause of the shut-o ff disappears, the boiler starts
up again and continues to operate normally.
While the boiler is shut o ff for safety reasons, it is possible to attempt
to restore normal operation by switching the appliance o ff and on
again using the ON/OFF button on the control panel.
If the boiler still indicates a safety shut-o ff , switch it o ff . Make sure the
external electric switch is in the OFF position, shut o ff the gas valve
and contact a quali fi ed technician.
Safety shut-o ff due to insu ffi cient water pressure
If the water pressure inside the heating
circuit is insu ffi cient, the boiler will
perform a safety shut-o ff . On the display
fl ash “Err” and the code -
Err/108 -
for
Insu ffi cient water pressure -- see the error
table .
Check the water pressure on the pressure
gauge and make sure that is between 0.6 and1.5 bar when the system
is cold. If the pressure is just under the minimum re fi ll the system by
open the valve under the boiler.
If the pressure drops very frequently, there may be a water leak at
some point in the system. If this is the case a plumber should be
contacted.
Operation shutdown
This type of error is “non-volatile”, which means that it is not removed
automatically.
On the display fl ash Err and the error code -
es.
Err/501 , and
appear the symbol .
In this case the boiler does not restart automatically, but it may
be reset by pressing the button. If the problem manifests
itself again after several attempts to reset the appliance, contact a
quali fi ed technician.
