Ok so this is a bypass without valve so in your case I do not see what prevents the water from circulating in the boiler even when the stove is running ... So a certain% of cold water will not pass the stove and so it is in serial and parallel installation at the same time ... or so I understood nothing?
Yes, we can say that it is a serial and parallel assembly at the same time. When the stove is stopped it is parallel, and the water does not circulate there. When the stove is lit it becomes a series by the action of the integrated circulator.

Mmmm stopped during the heating period you mean? So if I understand correctly: the regulation on the ignition of the edilkamin is done on the T ° of the water (whose return would be too hot ??) and not, as on the oil burner, with an optical or ion cell ?
It is the T ° of the fumes which is used to control the whole ignition procedure:
1. measurement of the T ° of the fumes
2. starting the extractor and switching on the resistance
3. if the T ° of the fumes increased by 15 ° stopping the resistance
4. if the T ° of the fumes has increased by 90 ° change to normal operating mode, depending on the T ° of the water.
In a pure series connection, return water, for example. at 40 °, what will happen?
in 1. the stove will measure still air at room temperature, 20 °, or even less if direct exhaust.
In 2. the extractor will blow air which will be heated by the return water. let's say that this air will be at 37 °. the flue gas temperature probe will measure this and cut off the resistance immediately, while the fire has not yet started => failed start-up, stove in error.
Another method would be to raise the 15 ° to 30 °, but we have faster wear of the resistance.
Finally there is the question of the linearity of the mixing valve, supposed to be better as well.
