3.1 ELECTRONIC CARD
The electronic card of “SUPER FOUR”
boilers is equipped with control leds
which signal some of the possible failu-
res that can cause an irregular and/or
improper operation of the appliance.
The leds are arranged on the card as
indicated in fig. 11 and marked with the
following wordings:
– “RICHIESTA” (5 fig. 11): green led ali-
ght on demand for D.H.W. or heating.
– “LD1” (8 fig. 11): red led alight to
indicate FM 31 programmer is
blocked.
– “LD2” (11 fig. 11): green led alight
when electric power is reaching the
card. Red led flashing to indicate
absence of water.
3.1.1 Devices present
on electronic card
The electronic card of the “SUPER
FOUR” boilers is equipped with the fol-
lowing devices:
– “MET-GPL” connector (10 fig. 11)
The “L.P.G.-MET” connector link must
be inserted on the type of gas for
which the boiler is arranged.
– “POT. ACC.” trimmer (7 fig. 11)
The electronic card has an “IGNI-
TION PRESSURE” trimmer for
varying the pressure level upon igni-
tion (STEP) of the gas valve.
According to the type of gas for
which the boiler is arranged, the
trimmer must be regulated so as to
obtain a pressure of approx. 3.5
mbar at the burner for natural gas
and 7 mbar for L.P.G. (G30 - G31).
To increase pressure, turn the
trimmer clockwise; to reduce pres-
sure, turn the trimmer counter-
clockwise.
Fig. 12 gives an indication of where
to set the trimmer according to the
type of gas used.
Before regulating the trimmer,
make sure that the “L.P.G.-MET”
connector (10 fig. 11) is connected
to the type of gas for which the boi-
ler is arranged.
NOTE: After setting the pressure
level upon ignition (STEP) according
to the type of gas, check that the
pressure for heating is still at the
value previously set.
– “ANN. RIT.” connector (3 fig. 11)
In the heating phase, the electronic
card is programmed to include a
burner technical delay interval of
approx. 2 minutes, which occurs
both at system cold starting and at
subsequent re-ignitions.
The aim is to overcome the problem
of repeated ignition and turning off
with very short time intervals
