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
PAR 01 in kW
0 = 25T; 1 = 25/55; 3 = 30/55
Hydraulic configuration
0 = rapid
1 = storage tank with
thermostat or heating only
2 = hot water tank with
PAR 02 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.

Solution
- Contact the Technical
Assistance Centre
- 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
- Check the sensor is
working
- Check connections
- Check the sensor is
working
- Check the integrity of the
electrode and check that it
is not grounded

Solution
- Check the integrity of the
electrode and check that it
is not grounded
- Check the integrity of the
gas valve and the card
- 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 for the presence
of water hammer on the
hot water system and, if
present, mount a water
hammer arrestor
- Check for any abnormal
requests on the room
thermostat
- Contact the Technical
Assistance Centre
- Contact the Technical
Assistance Centre
- Contact the Technical
Assistance Centre
- Carry out the self-
calibrating procedure (see
the specific section)
- Check delivery sensor
operation and position
