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
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 = bithermic
4=instant with solar power input
5 = open vent
6 = boiler with heat pump
Gas Type Configuration
PAR 03
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 "Automatic 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
burner
out the entire phase of "Automatic self-calibrating procedure"
described in the specific section.

- Check the electrical
connection of the smoke
probe
- Contact the Technical
Assistance Centre
- Check the connection cable
between the fan and the
board
- Check for any clogging in
the pipe which takes the
condensate to the siphon
