The ext probe is the one supplied with all okofen boilers.
The T ° that I am measuring is of course taken at the same place (5 cm from the probe)
- Not good calibration: no because the difference in T ° is not constant
- the scale is not good: I do not mind changing it, but I would be the only one for whom we change this scale: all the others would be good and not mine. and they know how to change this scale?
thank you all the same !!!!
I accept all ideas !!!
But there are a lot of anomalies per square meter in this room !!!! so defective material may be, but boiler + solar tank + freezer (may be) ... it seems curious
Electromagnetic disturbances
Very good remark from Swift2540 because unimaginable that the manufacturer provides a probe incompatible with its equipment, moreover repeatedly.
In addition, the problem exists on the solar water heater and the fairly independent boiler.
On measuring devices there are often adjustment or calibration potentiometers, even contactors allowing to change the probe and an error in the position of such a contactor can falsify everything !!
I had this type of problem with a supplier after a repair following a lightning strike and he could no longer operate after repair, and I had to look in every corner of the electronics to notice small contactors and ask their duties and what had to be the correct position! A simple change and everything worked !! I thus saved 1000 € of repeated and unproductive trips of the technician !!!
The electronics are very complex and the technicians do not know everything !!
I would tend to limit the problem to a single supplier like Okofen by removing all interaction with solar, so as to put Okofen in a situation where only his equipment is derailed and to say to him: look, there is only your equipment, nothing. from another manufacturer interacting and yet not working well, please resolve under your warranty.
In short, a well-posed problem is half resolved !!
In fact the only hope to get out of such Kafka-worthy situations is to break the system down, simplify it and test the pieces.
The boiler can work without solar water heater a priori?

Sorry, nothing will replace the probe replacement test with a fixed value: this is the only way to know if the circuit is messing up or is stable.
UPS: some electronics don't like it at all!
Certain circuits are sometimes too difficult (control program too demanding): I was shown the other day a gas boiler which went into safety, quite simply because it was not equipped with the right transformer!

chaboum, you ask a lot of questions without having answered the previous questions 
You won't get anywhere like that.
You don't know, this is the first thing to test in order to eliminate the problems one by one.
You'll never find out if you don't do the tests you were told to do in order. The first is either to put the probes with a very short wire directly on the boxes or fixed resistors instead. I already told you that I can put a handful of resistance in an envelope, what are you waiting for to unplug the probes and measure their resistance !?
Yes it is possible that the shit arrives by the sector, but for that it is necessary to go there by step, which you do not do !! Start by putting the probes or resistors as close as possible to the boxes, it's quick and easy to do !
Conclusion, instead of extending the list of questions, eliminate the avenues already considered!

A neighbor can have a powerful device, motor, coffee maker, boiler, etc. with thyristors without interference suppression (dead capacities) which emits KW of radio waves and disturbs everything, and not just the television, if by bad luck the son make the right antenna (it does not happen only by the sector) !!!
Everything is possible and it is necessary test by simplifying the system in pieces, such as inactivating all solar which is not Okofen (put Okofen probes (not solar ones) and see if it continues.
If this continues, Okofen's guarantee should not solve you and the Kafkaien problem is solved (apart from serin Okofen by phone).
If it stops, it's solar problem, see your supplier.
Otherwise you are never going to get out of it, unless you have a lot more knowledge and experience than the manufacturers and their technicians, but even then, it is a hassle to have the diagrams, plans and information to navigate and find their error, with the test equipment, such as measuring the voltages of the temperature probes, the voltages in the boiler electronics, power supplies, probes, controls, etc. spontaneous oscillator, if a component has characteristics a little tight !!) !!!
