Bonjour.
Strange this story of probe ...
At home for 7 years no problem with my box = int probe. and my ext probe. placed in North East. There is just a difference of 1 ° between the actual ambient temperature and the displayed temperature, I take this into account, I am too lazy to adjust (it's possible)

Good evening to shadocks: P On our old models, we had to record on a CF card. I did not cross the course! ... No registration. No rust in the heating body! Only in my joints! It's true you can adjust the opening and closing of the 3-way. Cordially.

OK !
63 ° instead of 60, it is a precaution ... do not go below 60 ° because of inertia ...
With my 60 °, it goes down to 57/56 °! I play with fire ;-) the limit being 55 ° to avoid condensation. But in full heating a few moments at this temperature, it is not dramatic

At home, the maximum boiler temperature is 76 °. The valve should close at 60 ° to avoid cold returns. This gives a good margin with maybe one or even two oscillations only. At home it is a little different it is the balloon charge circulator which stops at 60 ° of the boiler. The P...

I have a little trouble with the colors ... But on the graph: This drop in flow T ° seems to follow the drop in boiler T °, ​​which is not normal, in principle the valve 3 ways must open gradually to keep the flow T ° in accordance with the setpoint while the boiler T ° drops ...

Photo competition?

The answer was:
Limousin, wine of country of Corrèze (IGP), not far from Brive-la-gaillarde.

Goods.
Indeed, the mist, the hardwoods, the grass between the lines ...
But what is interesting to me: the grapevines seem to be planted on mounds! We see water, in the hollows, clayey soil?

Bonsoir.

I am a friendly competition ....
Tiebreaker, photo of a vineyard!
What region ?
While some recognize this landscape?
Thank you.

Check done ... your average cycles has increased
5180/14946 = 20,794 min.
5186/14952 = 20,810 min.
or rounded for P114: 21 min.

If your one-hour cycles continue, you have adjusted the boiler power properly.
