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
tS 0.1
1 = 25; 2 = 30
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 cock 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.

Solution
- Restore pressure
- check for any leaks in
the system
- Empty the system via
the drain valve on the
hydraulic assembly and
bring the pressure to
approximately 1.2 bar
- 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
- Replace the sensor or
the thermostat
- check that the pump
impeller is not blocked
- check the integrity of
the electrode and check
that it is not grounded
- check gas availability
and pressure

Solution
- check the rotation
of the system pump
impeller
- check the electrical
connections
- Replace the pump
- check the hydraulic
configuration using "tS
0.2"
- check the electrical
connection
- check the electrical
connection
- Set the parameter
tS 0.4 (combustion
configuration) to 0
- Replace the smoke
probe
- contact the technical
Assistance centre
- Replace the smoke
probe
- check the electrical
connection of the
smoke probe, if the
problem is not resolved,
contact the 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
- contact the technical
Assistance centre
- check with tester
- contact network

- 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
- check for blockage in
chimney
- Bleed the air from the
gas circuit
- check for blockage in
chimney
- check for blockage in
chimney
