Unscheduled maintenance

If replacing the electronic board , the user MUST set the
parameters as indicated in the table.
Type No. Description
Index showing boiler power in kW
PAR 01
0 = 25T
Hydraulic configuration
0 = rapid
1 = storage tank with thermostat or
heating only
PAR 02
2 = hot water tank with sensor
3 = two programmer
4=instant with solar power input
5 = open vent
Gas Type Configuration
PAR 03
0 = G20; 1 = G31
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 entire phase of "Self-calibrating procedure" described
in the specific section.
If the gas cock and/or the ignition/detection electrode , and/or the
burner , and/or the fan are replaced, the user must still carry out
the entire phase of "Self-calibrating procedure" described in
the specific section.
