CHARACTERISTICS

3. 1

ELECTRONIC BOARD

Electronic components are guaran-
teed to operate in a temperature
range from 0 (32) to +60°C (140
°F).
3. 1 . 1 Malfunctions
The led that signal errors and/or mal-
functions are indicated in fig. 12.
3. 1 .2 Devices
The electronic board is equipped with
the following devices:
– "HEATING POWER" TRIMMER
(10 fig. 13)
Adjusts maximum heating power. To
increase the value, rotate the trim-
mer clockwise, to reduce it, rotate
the trimmer counter-clockwise.
– "IGNITION POWER" TRIMMER
(6 fig. 13)
Trimmer to vary the gas valve ignition
pressure level (STEP). According to
the type of gas the boiler is designed
for, the trimmer must be adjusted to
Blinking red fan fault led. 30 minutes after the fan turns off, the board attempts to
restart it. To identify where the fault occurred in sequence/cascade installations, turn
the REMOTE/OFF/SUMMER/WINTER/RESET
tion and check where the red fault led blinks.

achieve a burner pressure of approxi-
mately 6.5 mm H
NATURAL GAS and 9.5 mm H
(0.37 "W.C.) for PROPANE GAS. To
increase pressure, rotate the trim-
mer clockwise, to reduce it, rotate
the trimmer counter-clockwise. The
slow ignition pressure level can be
set during the first five seconds after
the burner is lit.
After setting the ignition pressure
level (STEP) according to the type of
gas, make sure that the heating gas
pressure is still the previously set
value.
– "ANN. RIT." CONNECTOR (5 fig. 13)
The electronic board is program-
med, during heating, with a techni-
cal bur ner delay of about 90
seconds that is performed both at
cold start and subsequent ignitions.
This is to prevent rapid ignitions and
shutdowns that could, in particular,
occur in systems with high load los-
ses. Each time the boiler restarts,
after the slow ignition, for about 1
minute it will run at minimum modu-
lation pressure before moving to
the set heating pressure. The addi-

WARNING: the operation of plants with open ves-
sels is guaranteed only for static pressures above
0.7 bar (10.2 psi).
tion of a bridge will cancel both the
programmed technical delay and
the minimum pressure operating
period at ignition.In this case, the
time between shutdown and the
next ignition will depend on a 5°C
(41 °F) differential detected by the
heating probe (SM).
– DIP SWITCH (13 fig. 13)
For correct module operations, the
dip switches must be positioned as
indicated below:
– "Modureg Sel." connector (14 fig. 13)
The bridge must always be connec-
ted.
– "Albatros" connector (15 fig. 13)
The bridge must always be off. It is
only engaged in sequence/cascade
installations with several boilers.
WARNING: All the above operations
must be performed by authorised
personnel, otherwise the warranty
shall be invalidated.
