PROBLEM
The boiler water pressure is less than the value set in the SP01 (300mbar) technical parameter.
ACTION
After restoring the correct pressure, unlock the boiler by long pressing the control panel turn on
and off button.
CAUSE
A. Exercise pressure too low. Compare the pressure value indicated by the electronic control
unit by using the visualizations that appear by pressing the ↓ arrow twice when you are on
the display home screen.
B. Pressure transducer not working. Measure the power voltage of the pressure transducer on
contacts 37 and 39 of the electronic control unit. If the Voltage is different from 5 Volts (VDC)
replace the electronic control unit that does not power the pressure transducer. Otherwise,
measure the Pressure Transducer Signal Tension on contacts 38 (-) and 39(-) of the electronic
control
unit.
If the Voltage is proportional to the water pressure (0.8bar plus 0.8 volts – 1 bar plus 1 Volt
etc etc) then replace the electronic control unit that does not correctly detect the pressure
transducer signal. If the Tension is not proportional to the water pressure, replace the
transducer and its connecting cable because they do not work properly.
Y
Disconnect the fumes
extractor's cue capacitor
to
measure the
Resistance. Does the
Capacitor's
Resistance
increase to become ∞?
From the System – Output Test
menu, start the Fume Fan Test,
change the Extractor Speed
setting to different values, and
measure the Fumi Extractor
Power Tension on contacts 3
and 4 of the Electronic Center.
Does the power voltage of the
fumes
extractor vary
proportionally to the speed
setting?
Y
Replace the Fumi
Extractor, which has
internal frictions that do not
allow it to rotate at
maximum nominal speed.
NO
Sostituire il Condensatore di
Spunto dell’Estrattore perché è
difettoso o danneggia to.
NO
Replace the station that does not
feed the Extractor correctly.
