Patrice, if you have two circuits and a single probe, it is surprising that it is not on the radiators ... it may still be feasible?

And when you have put the compensation 0 on the PC, it may be necessary to correct the curve (if it was adjusted to the nose without having deactivated the probe to determine foot and slope ...)


I have a doubt: with a single probe, we can have two factors of compensation ????

I do not see how a room sensor placed in a room supplied by a circuit 1 validly "influence" a circuit 2 ???

However, I have a vague memory of wiring scheme, and it possible to add a probe per circuit ...

I think that one of the two factors is acting in the void !!!

Are you sure ???

Because I would finally understand your operation in almost unique cycle for several days, quite unusual (euphemism) ...

I think the same thing, to have a continuous cycle, the 1 500L must serve buffer! .... As the boiler can not heat enough to reach its limits T °, ​​it turns, turns ..

I ONCE once a cycle of 3 days in the middle of winter (neutralized room sensor) exceptionally, the losses = the heating of the balloon.

Continually trying we finally succeed. So more it fails, the more likely it is that it works.

Did, if his balloon was integrated, he would not have a single continuous cycle but 1 or 2 a day, or even 3 with long stops (while he has 24h of burner / day), right?

edit: saw the answer of manet ... ok, but a 32kW which rowed to heat a BT of 1500l, it would really have that its house is a strainer (I remember that Roy heats 500m ² with 20kW - perhaps not with 600m but anyway in Switzerland) ...

(Patrice's boiler must be direct screw otherwise it would do at least one start a day after stopping for aspi?)

For the probe, Patrice confirmed that he had only one, and that is on the PC - the other factor does not act simply.

But it might be more sensible on the circuit radiators (instead of RT that it may be) - it would be enough to connect the cable on the other circuit if there is way to move the probe (and if the radiators are upstairs, could there be way to extend the cable without breaking everything?)

Did your say:
"I would be a little more nuanced: having a PCBT and a house with a good window to the south and a huge bay to the west, I have a probe + correction factor (out of 4 I believe)."

unlike you, indeed, at home where I disabled the probe because of inertia, I do not have a window to the south.
By cons in the workshop where I have large solar gain and less inertia (heated walls on ITI), I have the probe, but in case of great sun I prefer to put on reduced (compensation 0, it serves me remote control in fact), which prevents me the cut up to 1 ° under T required room and the big delay to go back that I found frankly uncomfortable.

breaking up to 1 ° under T ambient demanded

On the V2 23 M version of the white regulator, it cuts at (T ° + hysteresis) - 1 °. It's much more comfortable! ... I check it every night to 3 or 4 H in the morning.

yes we had already talked about futura, I have no bowl with the 2.27 it descends 1 ° below what we put as hysteresis ... we compared records that did not say the same thing elsewhere ( the most recent ones do not have this defect either, must believe that I have just the bad version between) - same also with the limit T ° of heating ext.

Bonjour à tous
yes I'm sure my BT is not connected.
My boiler continues to run in almost continuous cycle (yes it stops in suction mode).
With a survey this morning and a less cold night, the boiler has run 83 hours since Friday 15h30 on 88.5 possible.
I put a usb key in the machine or I can email you the measurements of these last 5 days.

Good day to all

The measurement "x hours of operation" for "x hours elapsed" does not mean that there has not been a brief stop during filling; hours are rounded off ...

Over the same period, the variation of the counter of the number of starts and the number of ignition would give our famous "cycles".


OK for the BT. At this time, with negative temperatures, and a well sized boiler, it is possible to have a continuous or quasi-continuous operation.

Obviously, at the first glimmers of warmth, this is no longer the case ...

This is exactly why I say that we must be careful not to think that the way in which we each proceed is "the" and "the only" solution ... A kind of "single thought".

I didn't write anything else. And nothing wanted to "demonstrate" else ...

My way of proceeding, which is contrary to what Dirk had said, suits me. And hire me alone. Besides the relative "bioclimatism" of my house, I am not afraid either at the idea of ​​putting a blanket around my legs if I remain "wedged" on the sofa in front of the TV ... Nothing shocking about that, because I remember my youth when there was only the stove and the wood stove ... When I returned to my room, there was often ice in the window, interior side ... So yes, it is also necessary to integrate the level of requirement of each in the setting we adopt ... On the other hand, I am quite obsessed with wasting energy [remember my remark on drawing off hot DHW just to brush your teeth ...]. Same here, if I cancel the action of the probe. Solar gains are not "valued". The boiler continues as if it did not exist. The living room is overheated in the afternoon. And in the evening it does more than good (because there are still effects of overheating). I prefer to limit the overheating, to relieve the boiler and in the evening possibly to be "a little tight" ... What I called a "compromise". I believe this corresponds to coeff 4 for my probe.

These 5,5 downtime may very well be 35 stops of about 10 minutes on average. And so there will be 35 cycles, an average duration of 2,3 hours (which is fine!).

It's just for us to understand each other.
