Unscheduled maintenance

If replacing the electronic board , the user MUST set the
parameters as indicated in the table and in the sequence shown.
Type No. Description
Index showing boiler power in kW
tS 0.1
0 = 24; 1 = 25; 2 = 30; 3 = 35; 4 = 40
Hydraulic configuration
0 = rapid
1 = storage tank with thermostat or
heating only
tS 0.2
2 = hot water tank with sensor
3 = bithermic
4=instant with solar power input
5 = open vent
Gas Type Configuration
tS 0.3
0 = G20; 1 = G31; 2 = G230
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 valve and/or the ignition/detection electrode , and/or the
, and/or the fan are replaced, the user must still carry out
burner
the entire phase of "Self-calibrating procedure" described in
the specific section.
