9.4 Description of the automatic ignition, step by step.
1.
The boiler goes into Run mode, if the O
2
level is higher than the limit “Go to start up O
2
%” after
the “Delay ignition” timer has run out, it switches to “Ignition” and goes to step 2, but if the O
2
level is low it stays in run mode.
2.
The Stoker auger feed in “1. Start fuel”, and stop.
3.
Ignition goes on, and at the same time the present O
2
will be saved in the memory.
4.
When the O
2
drops more that the “Oxy. difference” value, the combustion fans start, on the
power set in “Startup/ Output %”, and help the igniter to get more flame, if not it go to step 10.
5.
After the timer “Fuel delay” are out, the Stoker starts to feed in fuel.
6.
When the O
2
again drop more that the “Oxy. difference” value, the ignition stops, but the
combustion fans keep on running, on the power set in “Startup/ Output %”.
7.
When the O
2
for the 3. time drop more that the “Oxy. difference” value, the controller goes into
run mode. If not, it goes to step 15.
9.5 Ignition alarm.
A.
Ignition timeout
10. If the O
2
don’t drops, before the end of the timer "Ignition timeout"

all gasses are blown out, so no risk of explosion in case off restart
B.
Startup timeout.
15. If the O
2
don’t drop enough to go to step 7, before the end of the timer "Startup timeout"
16. A alarm will come up on the display "Startup timeout"
17. The fans go on, and the flue fan keep running in time known as "Flue fan delay stop" to be sure
all gasses are blown out, so no risk of explosion in case off restart
9.6 Ignition restart.
20. The user can only restart the boiler after ending step 12 or 17.
21. If the ignition is restarted, without the boiler being in Run mode for more than 15 min., it is only
