3.2 TEMPERATURE SENSOR
AND WATER PRESSURE
TRANSDUCER
Antifreeze system made up of the NTC hea-
ting sensor that activates when the water
temperature reaches 6°C (43 °F).
Tables 4 - 4/a show the resistance values
(Ω) that are obtained on the sensor as the
temperature varies and the transducer
values obtained as the pressure varies.
When sensor (SM) is interrupted, neither
of the boiler's heating services will func-
tion. With D.H.W. sensor (SB) interrupted,
the boiler will only work in heating mode.

ELECTRONIC IGNITION

Ignition and flame detection is controlled
by two electrodes located on the burner.
These guarantee maximum safety with
intervention times, for accidental swit-
ching off or gas failure, of within one
second.

ter, and verify that green led (

tion of signal indicating that the control box

has "locked out".
– Gas failure
The control box runs through the cycle
normally sending electric power to the
ignition electrode. The electrode conti-
nues spark discharge for a maximum of
10 sec.If the burner does not light, the
lock-out indicator will light up.
This may occur upon first ignition or
after long periods of boiler lay-off when
there is air in the pipes. It may be caused
by the gas cock being closed or by one of
the valve coils having a break in the win-
) lights up to
ding, so that the valve cannot open.
