ÖkoFEN boiler - Follow-operation

[Did67]

I correct myself:

This is parameter 140 "Energis.data CF"

0 = no recording
1 = save

And parameter P141, which sets the data recording interval, in seconds


So check that your 140 is on 0 (or possibly -1; I seem to remember that it goes on -1 when there is no CF; when we introduce a CF, we have the choice between 0 - do not save or 1 - save)

thank you for the answer .
In fact, following a power failure, this message was displayed when the boiler turned back on: No CF card, and since it no longer works ... We tried to turn it off, turn it back on,. .. but we still have the same message.

Hello,

The 2010-2011 heating season is over, which will provide an update on the various settings of the boiler and its consumption.
I take this opportunity to communicate to those interested in an Excel spreadsheet that allows you to view the different parameters of the boiler. Regulation has so many parameters that putting them together has allowed me to better understand their meaning and understand how they interact.
I started with a paper version provided on the site http://granuleconso.free.fr that I put in my sauce.

FYI, I remind you that I have white regulation.
Good luck to those who are still struggling ...

Hello again,

FYI, below is the list of actions that have allowed me to improve the operation of the boiler while reducing its consumption and increasing comfort in the home:
- Insulation of the rooms: starting with the living room because it was this room that was the most poorly heated. Ideally, the insulation of the house, including the roof, should be completely resumed, but I limited myself to the simplest works (which were nevertheless quite effective).
- Insulation of the heating and hot water piping: for the most part, there are still uninsulated pipes in inaccessible places.
- Balancing of radiators: with prior replacement of the tee and / or tap of certain radiators which had become completely wedged.
- Adjustment of the parameters of the boiler, taking inspiration from the many posts found especially on this forum, but also on http://granuleconso.free.fr (see previous post).
- And of course, correction of the bugs of the initial installation: 3-way valve upside down and non-initialization of the regulation for the Pellematic boiler, which meant that some parameters were not accessible.

What I remember from all this is that the functioning of the hydraulic circuit is at least as important as what happens at the level of the boiler.
It is one thing to produce heat with the boiler, this heat must also be able to be transmitted correctly to the house via the heating circuit (cf. V3V, balancing of radiators, insulation of pipes ...). It is necessary after that this heat is preserved as long as possible (insulation of the house).
Hope it helps ...
cordially

Like Dupont and Dupond, I would even say more: the regulation of the circuit is much more important than the parameterization of the boiler. The drops in efficiency following modulation are low (2 to 3%), the consumption of the igniters, etc ... also low. So even a "catastrophic" operation (incessant on / off) will have little impact on the performance (barely a few%). It is more in relation to wear that it raises questions ... In short, with some exceptions, the combustion control plates do their job very well, even when it is not optimum. This is not the place to look for gains!

On the other hand, it's still better to have a boiler that "runs like a BMW" ...

On the other hand, any error in the regulation of the circuit results in "calories thrown" out of the window! And whatever the yield, it's pellets thrown out the window. And there, it directly impacts the portfolio. So heating curve (slope and base of the curve), programming of lowering periods, setpoint temp (comfort mode and lowered mode, etc.), maximum temp in comfort mode and in lowered mode are crucial points where we have quickly scratch 10 or 15% of consumption.


Since everything is on the boiler, people are confused.

The "plate" which regulates the compbustion, it is on the "pellets control". You have to remove the cover and play with the wheel. Heating regulation on regulation ...

Thank you for sharing this info. I once again express my interest to see treated on this forum the pump setting. I would start well, but my skills being what they are, I would prefer someone else to start . On the user manual of mine, I see interesting curves, flow, water height, etc., but I am not able to put them into practice on my installation. And on Hervé Silve's website, I don't have the level to understand everything. Not a specialist who wants ...

Do you happen to have a Grundfos Alpha2 by any chance?

[dhaulagiri]

Hello,

Mine is an OEG. From memory, I believe the specific model is OEG CPAE 55/25.

Obviously, all our circulators being different, it is less easy to discuss that than of the boiler even if the "theory" is the same for all. And it is precisely the theory that matters, right? Now, I may be the only one who wants to take my head with this or the only one for whom it seems complicated, as you wish ...

[tomgey]

Ah ok, because I have the Grundfos where we can also settle a lot of things. I do not dare too much because I am afraid that it will interfere with what the regul does ...
