I have formatted your message (so that the image is displayed immediately, you have to put [img] before% 20le% 20 "code"% 20and [/ img] after).

I do not understand what you mean.

So let's resume your image:

- the departures and returns to the circuits are on the left [well, it's the top, your photo is "lying"], I think ...
- Check the temp frieze 55 if I read (???)
- The return is to 45 °, so much cold logic ... ... Calories heated home.

With a foot at 45, by adding the "ba" (slope * difference in temp), the calculated departure (departure instruction) should be around 60/65 ° ... So with a small difference, the V3V seems to act, and act in the right direction ...

The starting probe seems to be stuck under the insulation, where the little black cable goes inside. She is well placed ...

If you let it, you'll get too hot!

It's the other way that it's wrong with you! [I have to stay clear!]

Therefore commend the smallest possible distance, waiting for the temperatures stabilize and rebuilt the photo ...

It is indeed that. Sorry for the picture layer, it has to come from my phone. Yet it appears right at the base. I would take the next the other way.

I put a photo of the v3v fully open yesterday in manual, an example or my return temperature is higher than departure.

In the meantime I have set foot in 20 to redo the photo.

That one, it intrigues me !!!

It is "mathematically" impossible ...

Still remains:

a) the inertia of the water even hotter party returns, while at the other end, the temperature dropped (lower boiler Temp because the reserve runs out)?

b) thermometers needles that sometimes do not respond right away?

Hi Did
Tell me, can it not be a schmilblick in the settings at home, which would make that as soon as the boiler is not burning (or achieved t °), the V3V close?

I read about another forum (by you too!) it was necessary to set the boiler start temperature polished above the pump start temperature. At home, the 2 parameters are at 60 °. Can this affect the closing of V3V?

Here is a graph drawn with yesterday's data.
it is easy to see that the room raised t ° is always less than the requested t ° (T Amb1 focus on because I have no inner tube for T Amb2)
It also shows that T ° departure identified fluctuate enormously and it is systematically (when the boiler is no longer combustion mode) well below instructions.

Did67 poor, strong you are asked!

Here is the photo of this morning (in the place!), The set flow temperature was 26, and the temperature measured by the 46 regulation.

There is surely a schmilblic!

In the settings? I do not know.

Normally, the regulation should not cut the heating even if the boiler stops because it has reached its maximum; In any case, I do not know "action" of this kind (but I do not know everything; and the new generations of regulation, the Touch, are unknown to me ...)

Hard to read, the colors are not quite clear ...

Are you talented enough computer to export the data to an Excel spreadsheet, and then leave only the data of interest?

This photo is intriguing and may suggest that your V3V is upside down (including the color rim)

- We are in the blue, an almost closed V3V: theoretically, especially is sent back from the water, with almost no hot water from the boiler ...
- Or the start is almost 60, a few degrees below the temperature of the boiler (between 65 and 75)
- the return is much lower than the departure; it "turns" in the right direction ...
- With a reference to 26, ever in life you do should have a circuit at those temperatures

The first thing I would do would be to remove the engine and drive the V3V by hand, to see if everything works: you dismantle the block, and you put your V3V on an "average" position [you heat with radiators?]
