3.16 - ALARMS OF THE ELECTRONIC CONTROL BOARD
Refer to the third page on the screen and check the status of alarms in the third line.
Problem encountered
The boiler triggers alarm 1
"bottom door of burner open"
The boiler stops and triggers alarm 2
"no fuel in container"
The burner does not start and the control unit triggers alarm 3
"clogging of fuel in burner"
alarm 5
"storage tank and/or solar panels above maximum tem-
perature threshold"
alarm 6
"Triggering of the fire safety thermostat"
The boiler does not start up and alarm 7 is triggered
"Burner not ignited"
The boiler does not start and alarm 8 is triggered
"instability of boiler flow Probe 4"
One or more of the probes are unstable
This message is displayed on the screen:
"Alarm: probe disconnected or malfunctioning."
Solution
Check that the bottom door is shut and check the relative con-
tact of the micro-switch.
Check that there is fuel in the container and top this up if necessary.
Check for and remove any residue or fuel in the inlet of the burner.
If the fuel does not flow smoothly during the loading process,
it is likely that the fuel has caused an obstruction or there is a
fault with the motor of the feeding screw in the burner, in which
case you need to call the assistance centre.
This occurs when the storage tank and/or the solar panels are
at maximum temperature. The alarm resets itself automatically
when the temperature of the storage tank and/or solar panels
falls below the maximum temperature again.
Fault due to triggering of the (automatically resettable) fire
safety thermostat on the manifold of the burner. To reset this
alarm, press key 11 on the panel board (refer to section 3.12).
Before resetting this alarm, you must check that there is no
fuel or non-combusted material in the brazier of the burner,
and only then press button 11 to reset the alarm manually
(refer to section 3.12). If there is any non-combusted material,
it is likely that the igniter has burnt out.
In which case, manually remove the fuel, reset the alarm and
wait for the new ignition cycle to start. If this problem reoccurs,
call the assistance centre and ask to have the igniter replaced.
This problem can be due to overheating of the boiler or insta-
bility of the S4 boiler flow probe.
The only way to resolve this problem is to reset the system
manually by pressing button 11 on the electronic control unit
(refer to section 3.12).
If the error occurs and you are certain that the boiler has not
overheated, call the assistance centre and ask to have the
probe replaced.
The probes must be connected with a shielded cable to avoid
interference and ensure correct temperature readings. Refer
to section 14.
The probe may be disconnected or defective (in this case,
check the cable and replace it if necessary).
It is also possible that
"parameter 28 probe configuration"
has been set incorrectly.
In which case, call the assistance centre to have this checked.
