CHARACTERISTICS

The electronic boards are manufactured in
compliance with the EEC 73/23 low-voltage
directives. They are supplied with 230V.
The electronic components are guaranteed
against a temperature range of 0 to
+60°C.
An automatic and continuous modulation
system enables the boiler to adjust the heat
output to the various system requirements
or the User's needs.
3. 1 . 1 Fault finding
The indicator leds signalling irregular
and/or incorrect operation of the equip-
ment are indicated in fig. 16.
3. 1 .2 Devices
The electronic board is equipped with the
following devices (fig. 17):
– Connector "JP4" (4)
With the connector disconnected, the
boiler is ready to function with METHANE;
with the connector connected with GPL.
ATTENTION: It is essential that the opera-
tions described above be carried out by
authorized technical staff.
3.2

TEMPERATURE SENSOR

Antifreeze system made up of the NTC hea-
ting sensor that activates when the water
temperature reaches 6°C.
The heating sensor also works as a limit
thermostat turning off the burner when the
detected temperature is over 90°C.
Neither boiler services will work when the
sensor (SM) is cut off.
Tables 4 show the resistance values (Ω)

Flashing red LED to signal a problem on the post-condenser line.
Red LED on, ignition blocked/safety or fume thermostat tripped:
that are obtained on the sensor as the
temperature varies and the transducer
values obtained as the pressure varies.
