Checks
Solutions
Loc 22 Flame lost three times
Check that the ionisation current is above 4
(see section 8.22).
If the ionisation current is not over 4, check
the CO2 (see section 6.7) and restore it to
the correct value.
Check the ionisation spark plug and replace
it if necessary.
Check the integrity of the ionisation current
electric circuit cables.
Check that the flue exhaust is properly
protected against obstructions caused by
gusts of wind.
If the flue exhaust is on a vertical wall it must
be protected by a windproof grill.
Check that flue gas outlet is not in a area
where there is flowback, and that any
windproof chimney that may be provided is
really effective.
Loc 23 Software error on the control board
Replace the control board.
Loc 24 Software error on the control board
Replace the control board.
Loc 25 The two supply sensors (detail "35" of Figure
2) measure temperatures that are at least
10°C different for more than 60 seconds.
Check that the electrical resistance of the
two sensors matches the graph in section
8.24.
If either or both of the sensors are not within
the correct values, replace them.
Loc 26 Software error on the control board
Replace the control board.
Loc 27 Too many system loads in one hour
Check the pressure switch calibration
pressure
- when the pressure drops below 0.6 bar
must appear FILL;
- when the pressure rises above 1.5 bar
must disappear FILL.
If the pressure switch is not calibrated
correctly, it must be replaced.
Check that there are no water leaks from the
central heating system.
If the system has a leak, it must be repaired.
Loc 28 System filling time too long
Check the pressure switch calibration
pressure
- when the pressure drops below 0.6 bar
must appear FILL;
- when the pressure rises above 1.5 bar
must disappear FILL.
If the pressure switch is not calibrated
correctly, it must be replaced.
Check that there are no water leaks from the
central heating system.
If the system has a leak, it must be repaired.
Loc 29 Software error on the control board
Replace the control board.
Loc 30 Software error on the control board
Replace the control board.
Loc 31 Software error on the control board
Replace the control board.
Loc 32 Software error on the control board
Replace the control board.
Loc 33 Software error on the control board
Replace the control board.
