Circuit Board Replacement

Should the circuit board be replace, the engineer MUST set
the parameters as indicated in this table and in the sequence
shown.
Type No. Description
Index showing boiler power in kW
PAR 01 5 = 25 (MURELLE REVOLUTION 25)
6 = 30 (MURELLE REVOLUTION 30)
Hydraulic configuration
0 = combi
1 = system
PAR 02
2 = N/A
3 = N/A
4=instant with solar power input
Gas Type Configuration
PAR 03
0 = G20/G25; 1 = G31
To enter "Parameter setting and display"refer to the indica-
tions 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 valve and/or the ignition/detection electrode , and/or
the burner , and/or the fan are replaced, the engineer must still
carry out the entire phase of "Self-calibrating procedure" de-
scribed 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
- 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
- Check gas availability and
pressure
- Check the operation of the gas
valve
- Check the sensor or thermo-
stat 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
- Check the operation of the gas
valve
- Check the rotation of the pump
rotor
- Check the electrical connec-
tions
- Replace the pump

Solution
- Check the electrical connection
- Set the parameter PAR 04
(Combustion configuration) to 0
- Replace the smoke probe
- Contact the Technical Assis-
tance Centre
- Replace the smoke probe
- Check the electrical connection
of the smoke probe, if the prob-
lem 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 conden-
sate to the siphon
- Check that the siphon is not
clogged
- Wait 1 hour and try unblocking
the board again
- Contact the Technical Assis-
tance Centre
- Replace the return probe
- Check parameters
- Contact the Technical Assis-
tance 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 connec-
tion
- Check gas valve and board
- Carry out the self-calibrating
procedure (see the specific
section)
- Check delivery sensor opera-
tion and position
- Check gas valve and board
- Check gas valve and board
- Check gas valve and board
- Check gas valve and board
- Check electrode
