Which control, when hitting flow temp+5 and then shutting the burner off, does the boiler software look at first, the anti cycle time (say 10 mins) or the hysteria temp drop (say 6 degrees).

What I mean is, if the boiler goes into anti cycle mode, will it restart when the hysteris drop is reached first or the anti cycle time? If it is the hysteris, then surely this is a good thing (as long as it can be user adjusted) as it guarantees that the internal temp has dropped enough for a possible final burn before getting up to room sat set point?

Sorry if it's a dumb question.

I would guess that the anti-cycling time is absolute, once triggered, nothing can happen until it times out..
