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
2 = 40
Hydraulic configuration
0 = rapid
1 = storage tank with thermostat or
PAR 02 heating only
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.

Solution
- Check the rotation of the
pump rotor
- Check the electrical
connections
- Replace the pump
- Check PAR 02 "hydraulic
configuration"
- Check the electrical
connection
- Check the electrical
connection
- Set the parameter PAR 04
(Combustion configuration)
to 0
- Check the sensor is working
- Replace the smoke probe
- Replace the smoke probe
- 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
- Check that the siphon is not
clogged
- Wait 1 hour and try unblocking
the board again
- Contact the Technical
Assistance Centre
- Replace the return probe
- Check parameters
- Contact the Technical
Assistance Centre
- Check the voltage
- Contact your network provider
- Contact your network provider
- Check the ignition/detection
electrode
- Check the gas supply (open
valve)
- Check mains gas pressure
- Check that buttons are
working
- Check the OT electric
connection
- Check gas valve and board
- Contact the Technical
Assistance Centre
- Contact the Technical
Assistance Centre
- Carry out the self-calibrating
procedure (see the specific
section)
