Antifreeze system made up of the
NTC heating sensor that activates
when the water temperature reaches
6°C (42 °F).
Tables 3 - 3/a include the resistance
values (Ω) that are obtained on the
probe (SM) when the temperature
changes and those on the transducer
when pressure changes.
The module does not work when the
heating probe (SM) is cut off.

Ignition and flame detection is con-
trolled by two electrodes located on
the burner. These guarantee maxi-
mum safety with intervention times,
for accidental switching off or gas fai-
lure, of within one second.

should ignite within max. 10 seconds.
Failed ignition consequently lighting the
appliance block signal may occur due
to the following:
– Ignition electrode does not spark
Only gas is supplied to the boiler and,
after 10 sec., the block led turns on.
It may be caused by the fact that the
electrode is cut-off or is not secured
in the ignition transformer terminal.
– No flame detection
At ignition, the electrode continues
to spark even though the burner is
on. After 10 sec. it stops sparking,
the burner turns off and the block
led turns on.
The detection electrode wire is cut-
off or the electrode is grounded;
the electrode is worn and requires
replacement. The electronic board
is defective.
A sudden blackout immediately turned
off the burner, when power is restored,
the boiler will automatically start.
