Loc 17 Software error inside the
command board
Replace the command and control board.
Loc 18 Flame present 10
seconds after gas valve
is closed
Replace the gas valve or the command and control
board.
Loc 19 Flame present before
ignition
Replace the gas valve or the command and control
board.
Loc 20 Flame lost three times Control: that the ionisation current is at a value over
60 (follow the procedure in chapter 8.20)
Controllare: che lo scarico dei fumi sia opportunamente
protetto da ostruzioni causate da folate di vento
If the ionisation current is not over 60, the CO2 must
be checked (follow chapter 6.8) and restore the correct
value. Check the ionisation electrode and replace it if
necessary. Check the integrity of the ionisation current
electric circuit cables.
If the fumes exhaust is placed in a vertical wall it
must be protected with a wind-proof grid. If the fumes
exhaust is positioned on the roof, make sure that it is
not in an area of reflux and that any windproof chimney
pot is really efficient.
Loc 21 Not applicable
Loc 22 Not applicable
Loc 23 The two supply sensors
measure the different
temperatures for more
than 60 seconds.
Check that the electrical resistance of the two sensors
match the graphics in chapter 8.22;
Check that the central heating circuit flow rate is not
too low;
If one of the two or both sensors do not have correct
values, they must be replaced;
If the temperature difference between U1 and U8 is
greater than 30°C at maximum power and the flow
rate of the central heating circuit is low, the flow rate
must be increased;
Loc 24 The two fumes sensors
measure the different
temperatures for more
than 60 seconds.
Check that the electrical resistance of the two fumes
sensors match the graphics in chapter 8.22
If one of the two sensors does not match the double
fumes sensor must be replaced
Loc 25 Too many plant fills in
one hour
Check the pressure switch calibration pressure. FILL
must appear when the pressure drops below 0.6 bar
and must disappear when the pressure rises above
1.5 bar; check that there are no water leaks from the
central heating plant
If the pressure switch is not calibrated correctly, it must
be replaced. If the plant has a leak it must be repaired.
Loc 26 Plant filling time too long Check the pressure switch calibration pressure. FILL
must appear when the pressure drops below 0.6 bar;
check that there are no water leaks from the central
heating plant
If the pressure switch is not calibrated correctly, it must
be replaced. If the plant has a leak it must be repaired.
Loc 27 Software error inside the
command board
Replace the command and control board.
Loc 28 Software error inside the
command board
Replace the command and control board.
