4.1 ELECTRONIC PANEL
Made in accordance with the Low Voltage
EEC directive 73/23, supplied with 230
Volt; via a transformer it sends 24 Volt to
the following components: gas valve, safety
stat, C.H. and D.H.W. sensors, external
temperature sensor (optional), modulator,
water pressure transducer, smoke stat,
room stat or “Logica Remote Control”.
An automatic and continuous modulating
system allows the boiler to adjust the
p o w e r t o t h e v a r i o u s p l a n t o r u s e r
demands. The electronic components are
guarant eed t o work in a t emperatur e
range between 0 and +60 °C.
4.1.1 Functioning faults
The leds that show an irregular and/or
incorrect functioning of the apparatus are
shown in fig. 16.
4.1.2Devices
The electronic panel has the following
devices:
– Trimmer “POT. RISC.” (10 fig. 17)
It regulates the maximum value of heat-
ing power. To increase the value turn the
trimmer in a clockwise direction and to
decrease it turn the trimmer in an anti-
clockwise direction.
– Trimmer “POT. ACC.” (6 fig. 17)
Trimmer for the changing of the ignition
pressure level (STEP) of the gas valve.
According to the type of gas for which
the boiler is predisposed, the trimmer
must be regulated so as to provide the
burner with a pressure of around 3
mbar for methane gas or 7 mbar for
but ane gas (G30) and pr opane gas
(G31). To increase the pressure turn the
trimmer in a clockwise direction, to
decrease it turn the trimmer in an anti-
clockwise direction.
The level of pressure of slow ignition is
able to be set during the first 5 seconds
from the starting of the burner.
Af ter having established the level of
pressure at ignition (STEP) according to
the type of gas, check that the heating
gas pressure is still on the value set
beforehand.
– Connector “MET-GPL” (7 fig. 17)
With the connector disconnected, the
boiler is ready to function with METHANE;
with the connector connected with LPG.
– Connector “ANN. RIT.” (5 fig. 17)
The electronic panel is programmed, in
heating phase, with a technical pause by
the burner of around 90 seconds, both
at the beginning when the plant is cold
and in the subsequent startings.
This is so to avoid ignitions and switching
off with very short intervals, that may in
particular be found in plants with high
losses.
At every restarting, following the period
of slow ignition, the boiler will position
itself for around 1 minute to the mini-
m u m m o d u l a t i n g p r e s s u r e t o t h e n
return to the set value of heating pres-
sure. With the insertion of the bridge
both the technical pause programmed
and the period of functioning at minimum
pressure in the ignition phase will be
eliminated.
I n s u c h a c a s e , t h e t i m e t h a t r u n s
between the switching off and the next
ignition will be in function of a variance of
5°C, as shown by the C.H. sensor (SM).
– DIP SWITCH (13 fig. 17)
Ensure that the riders are inserted in
the position shown in order for the boiler
to work:
– Connector “Modureg Sel.” (14 fig. 17)
With the bridge disconnected the boiler
is predisposed to function with the SIT
gas valve, and with the bridge connected
it is predisposed to function with the
HONEYWELL gas valve.
ATTENTION:
All of the operations described above
must be carried out by authorised per-
sonnel.
4 CHARACTERISTICS
Green led off
in case of no electricity
Red led flashing: in case of
insufficient water pressure (*)
Red led flashing: problem with C.H. sensor (SM)
Red led flashing: coil of the modulator stopped
Red led flashing: problem in flame detector circuit
Red led flashing:
in case of C.H. safety valve
interception (*)
Red led flashing: lack
of communication with the
“Logica Remote Control”
Red led on: ignition failure.
Turn the selector
CR/OFF/EST/INV/UNBLOCK
in the position unblock ( )
to restore functioning
Red led flashing: safety stat
interception. To restore
functioning turn the selector
CR/OFF/EST/INVE/UNBLOCK
in the position unblock ( )
Red led flashing: fan or smoke
pressure switch fault.
After 30 minutes of the switching
off of the fan the panel will reactivate it.
(*) When all the leds from 0,5 to 2,5 bar are switched off check
the connections of the water pressure transducer.
