Unscheduled maintenance

If replacing the electronic board , the user MUST set the
parameters as indicated in the table.
Type Nr. Description
Index showing boiler power
tS 0.1 in kW
0 = 24; 1 = 30
Hydraulic configuration
0 = rapid
1 = storage tank with
thermostat or heating only
tS 0.2
2 = hot water tank with sensor
3 = two programmer
4=instant with solar power
input
Gas Type Configuration
tS 0.3
0 = G20; 1 = G31
Combustion configuration
0 = sealed chamber with
combustion control
tS 0.4
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
- Restore pressure
- Check for any leaks in the
system
- Check connections
- Replace the sensor
- Check connections
- Replace the sensor
- Check the integrity of the
electrode and check that it is
not grounded
- Check gas availability and
pressure
- Check the integrity of the gas
valve and the card
- Check the sensor or
thermostat connections
- Deaerate the system
- Check the bleed valve

to 0
- Replace the dual sensor
- Contact the Technical
Assistance Centre
- Check with tester
- Contact network provider
(ENEL)
- Contact network provider
(ENEL)
- Check the detection
electrode
- Check the gas supply (open
valve)
- Check mains gas pressure
- Check that buttons are
working
- Check the electrical
connection of the remote
control
- Carry out the self-calibrating
procedure (see the specific
section)
- Check that the delivery
sensor is attached to the
delivery pipe
- Replace the sensor
