Unscheduled maintenance

If replacing the electronic board , the user MUST set the parame-
ters as indicated in the table and in the sequence shown.
Type No. Description
Index showing boiler power
PAR 01 in kW
0 = 24; 1 = 30; 2 = 40
Hydraulic configuration
0 = rapid
1 = storage tank with ther-
mostat or heating only
PAR 02 2 = hot water tank with
sensor
3 = bithermic
4=instant with solar power
input
Gas Type Configuration
PAR 03
0 = G20; 1 = LPG
Combustion configuration
0 = sealed chamber with
combustion control
PAR 04
1 = open chamber with
smoke thermostat
2 = Low NOx
To enter "Parameter setting and display"refer to the indications
provided in the specific section.
Once the parameters in the table have been set, you must carry
out the "Automatic calibration procedure".
If the gas valve and/or the ignition/detection electrode and/or the
are replaced, the user must still carry out the entire phase
fan
of "Automatic calibration procedure" described in the specific
section.
