I'm using compressor cleaning with kg limit (15kg). It works well so I haven't even thought of using timed stops instead, but I thought I could share a couple of findings:
I noticed that after the set time period without feeding pellet, the compressor blow fired and then right away it started feeding pellet again like it would be in normal running phase. It took quite a while (several minutes) before it noticed that there was no light, and only then did it begin a normal startup, by feeding a normal startup dose and so on.
Since there now was a double dose pellet on the grate (normal startup dose + normal feeding for a couple of minutes) the result was oxygen level 0,0% and black smoke. Because of this I reckoned that it was supposed to be able to startup on leftover ember and continue running without using the electrical heating element at all. Well, I tried lowering the "time without pellet" to 170 seconds, just enough for the light level to drop to zero before firing the compressor blow, and since then it has reliably continued running without a startup sequence after every compressor cleaning. It ignites quite rapidly on the leftover ember (presumably some is left in between the two air pipes, just below the feeding auger) and the oxygen level drops to set value in a couple of minutes almost always without at all dipping below, so it certainly looks a lot better than when it tried to continue, failed, and did a restart. The longest I have been running without touching the burner (or removing ash from the boiler) is 3,5 tonnes of pellet, and then only a couple of holes in the grate were blocked with very little "ashcake" buildup, so it does seem to work.
