Parameter setting TEM Paradigma Ökofen

the same but as it annoyed me, I looked for or was the probes.
there are 3 in a metal support welded on the outside of the heating body under the insulation.

OKAY. Thank you. So if it's like that, I don't do anything at all !!!

FYI, I just stuff myself the instructions for the new TEM in a little more detail : apart from the improvements already mentioned above, I read this (page 36/50)

"" TD reg range "

Valve adjustment range on the flow temperature. When the flow temperature approaches the setpoint calculated for the flow temperature (....), the valve opens and closes more slowly to avoid any phenomenon of valve oscillation and pumping. The valve operating times are dynamically adjusted depending on the measured flow temperature. This correction occurs both at opening and at closing.


And there you go. All that remains is to ask Santa for a new TEM? Heck, just came by!

Finally, I would like to try.

In addition, in the improvements, to report the management of a second boiler (log, fuel) etc with an automatic reversing valve ! There, it is a real progress ... I believe more in the association of two specialized boilers rather than in mixed machines ... There is also the drying of slabs (it seems a bit silly)

Hello,
nothing serious about these probes ..
A slight difference is normal, since the components of the probes are different and the order in which they are connected to the metal pleats of the boiler can give a variation in contact temperature.

It is also possible that the connection cable is not "faradized" and this causes a disturbance in the data transmission via the probe cables passing alongside the boiler power cables.
in short, we are tweaking the data readings, the goal is reached in the settings and in the operation.

Happy New Year to all Pierre

Hello,
The equipment has been delivered (boiler, screws, rotex tank, the panels are placed on the roof, the silo! Remains the hopper)
I searched and found the ÖkoFEN manuals (user and installer).
I plunged in to understand before the arrival of the installer and the technician (end of January). the forums help me well (TEM regulation).
I have a question perhaps silly:
The boiler and its regulation can manage solar (7 level) but the ball combined Rotex SSC 538 / 16 / 16 has its own Regul. The what is going to be used?
This ball should it be considered as a combined storage or as a storage tank?
At the 16 page of Regul. TEM TPO probe denoted probe p15 ball is drawn into the boiler ...
Sincerely.

JC

Since it is a drain-back solar system, I am not sure that it is wise to have it managed by the boiler.
I would prefer to let it manage itself. on the other hand, there is a cable with dry contact cut-off to prevent the boiler from starting if the balloon is hot enough. In my opinion, this duplicates the boiler regulator probe which is offset in the balloon and which clearly sees that it is quite hot. so I won't wire this contact either.
note that doc solaris rather seemed to advocate the opposite; that is to say that the boiler does not have a probe which informs it about the temp of the balloon but that it is the balloon which informs by contact when the balloon is hot.
we should still be able to return a boiler probe in the pocket of the balloon would be better (ECS probe TBO)

I think we manage it as a storage tank, not a buffer.
first of all, the okofen modulating boiler does not need a buffer and it should be borne in mind that a buffer is a solution to the problem of non-modulating boilers such as wood-logs. accumulating trawl to redistribute it later is not energetically ideal because there are losses. It is better to "manufacture" the heat on demand. In addition, this balloon is small. Even when used in a DHW tank, there is still the icing on the cake with the return heater which can, on occasion, add a few additional solar calories (if available)
on the other hand I do not understand the utility of the 2nd exchanger in your version 16/16 instead of 16/0 ???

for the TPO probe, when there is no buffer tank, this probe is placed on the top of the heating body and sees the boiler temperature. normal, therefore.

[manet42]

Thank you very much, it's nice to have a specialist.
For 536/16/16 instead of 16/0:
Two hypotheses, the bad translation of the commercial doc and the installer (like me) was a bit wrong. The technical document in the cardboard box is clearer, an exchanger would suffice, but he maintains that it is good.
Or else, it was not mistaken, the parallel mounting of the two exchangers increases the heating power, favorable for a pellet boiler, it is indicated in the document that I read.
Anyway, this second exchanger can always be used later in the event of changes. of the installation without restarting everything.
I will therefore monitor the Okofen technician (another customer em ...) most of the problems seen on forum being due to regulation.
Sincerely.

Hello,
I looked at your excel file with your settings changes:

how much downhill did you go on 1.8? 2.4?
and at the foot of the curve? you are 40?

then you didn't tell us anything about your installation: boiler power? radiators? surface to heat?
thanks.

because I'm still in the settings. and just this hard night to have 20 ° of comfort. indeed, outside the weather has softened (around 8 to 10 °), I have been fine lately when it was colder ...
I am at 35.5 of a curve foot, and I was afraid of going up again, you went up to 40 ° (or you just give us the maximum) ??

please

Hello,
The installation is in progress, I finally have the explanation for the second exchanger. The circuit has nothing to do with Rotex schemes ...
The normal charge exchanger will be for heating the tank by the boiler.
The second exchanger (the one for a swimming pool) is used to heat the radiators. Two separate circuits: boiler and radiators with two circulators, a 3-way valve to close the heating.
The central exchanger in the chimney, originally intended for solar backup, will not be used.
It seems it is the way to recover the least solar calories.
I will try to draw the diagram.
Kind regards.

Here is the diagram

[dirk pitt]

this circuit does not seem very academic to me in the sense that there is no direct hydraulic connection between the water in the boiler and that in the heating circuit. it necessarily goes through two exchangers to heat the water in the radiators. hello performance!
in addition it requires always having the entire balloon at maximum temperature otherwise, no chance that the calories generated by the boiler want to go to the radiators.
the 3-way valve of the heating circuit may open, it will only circulate water at best at the temperature of the tank. It is not the purpose of a buffer ball.

even a simple buffer tank does not connect in this way.
in short, ask your heating engineer to show you an installation that works on this principle with someone else because I am very skeptical.

Hello,

Long discussion with the installer yesterday
Everyone stayed on their positions: me on yours, him on his diagram.
I summarize.
System developed with the technician who will come to start up the boiler.
Little loss in the water bath for the two exchangers.
The exchanger descends only 2/3 of the tank, only this part must be hot.
In my installation the temp. starting point never exceeds 50 ° so with a 60 ° balloon it will still work ... etc ...
As in any conflict, it had to come out. Having made my reservations, he applies his system and agrees to come back to modify it in the event of a malfunction (poor performance, insufficient heating, excessive consumption). There I trust him, he worked with friends for a heat pump, they were delighted with the quality of the work.
He bet his shirt that it will not happen.
He suggests that I give him my digital photos to put on his site as an example ....
Perhaps we should make a new post on this system for the rest because we are far from the subject: regulation.
cordially

JC
