Presentation: Adjustments boilers ÖkoFEN

[manet42]

I think that set off a new post where the owners would put their settings would be interesting.

Manet 42:
Lorraine (OT ° mini -15 °) 135m2, oversized radiators, average insulation, high inertia, and buffer tank for solar complement.
Limit comfort 18 °
reduced limit 12 °
Heating curve: 28 0,8 ° slope
Compensation: 5
Hysteresis: 0,5 °
120 anticipation
T ° max departure 62 °
T ° departure mini 20 °

Two programs to monetize the sun.
-Half season: comfort schedule 9h30-18h.T 48 ° ° mini ball, max temp 52 ° ball.
Atmosphere 19 3 °; reduced 17 5 °.
-Winter: Schedule comfort 7h30-21h30.
Atmosphere 19 5 °; reduced 18 °. No reduced from -12 / -13 ° ext.
T ° mini ball 62 °; Max temp ° 66 5
-In summer: stopped boiler, solar DHW
A follow other facilities?

Very good idea and a good season!

Garania:
Loire (OT ° mini -20 °) 140m2, 3 routes: No. 1 floor heating 80m2 No. 2 radiators 60m2 and ECS, new insulation 100mm glass wool, low inertia.

1 circuit
Limit comfort 16 °
reduced limit 11 °
Heating curve: 20 0,6 ° slope
Compensation: 2
Hysteresis: 1 °
anticipation 180min
T ° max departure 45 °
T ° departure mini 20 °
Atmosphere 19 5 °; reduced 19 °

2 circuit
Limit comfort 16 °
reduced limit 11 °
Heating curve: 22 0,8 ° slope
Compensation: 0
Hysteresis: 0,5 °
anticipation 0min
T ° max departure 45 °
T ° departure mini 20 °
Atmosphere 19 °; reduced 16 °


Schedule comfort 5h30 8h-and-17h 21h.T °

-In Summer: stopped boiler, electric ECS

Question: I just em'apercevoir when the boiler reaches 60 ° C, it restarts, 3-way valves closed, and those it opens only when I reach 66 ° C. Do you know how to open them 60 61 ° C or ° C?

Another thing I saw on my cicuit radiator, too little water law, 22 0,6 ° C and makes me set the cap at 31 ° C. Yet in the calculation formula should not be a cap?

[manet42]

In protected menu, there are two limitations:
mini hot -T. 60 °
-T Pump limit check if it is to 66 °? And make 61 °.
For the limit of the curve, I can not see.

Meric, I've already looked but can not find it, do you have the number?
I have a P281 60 °, this one START the pump, but the gates remain closed. I spent the 283 5 from 2 ° ° has no change.
In you they open well in 60 °?

[manet42]

P281 is for those trendy circulation pump on UW, load the buffer tank. It should not be your case?

The two parameters which I speak are for white control:
- Hot mini T: Minimum boiler temperature where the mixing valves are allowed to open.
-T Pump limit: T ° activation circulators. They can not operate below.
In installations without buffers, these values ​​should not be below 60 ° (avoid cold returns).

In fact the curve 22 ° / 0,8; T ° departure 31 ° roughly corresponds to an OT ° O °. There is perhaps not cold enough?

Indeed, several things combine:

- the board (not the regulation), manages a maximum temperature (a P2xx, I have to look at the instructions); whatever she receives as "orders", she stops ...

- Regulation maintains a minimum temperature, from which to protect the boiler, it closes V3V

- it is also she who gives the signal of a "need" (if the external temp is endehros of the heating limits, if I do not know what ...).

The summer has been there. Should I am back in the records, including the Pelltronic I do not know (but even the TEM, I do not remember everything!).

And indeed, the P281 is linked with UW port on which the charge pump is plugged in the case of mounting via a buffer. This port is on the board. So this setting manages the transfer of hot water from the boiler to the buffer.

The settings are displayed even when there is no circulator connected on! You can put whatever you want, nothing will change!

Hi the okofenistes,

Good idea this discussion, no doubt that this group of information will be useful to many.

If I may say so, it would almost indicate as average times of heating cycles, and the number of ignitions and boiler starts, it would see what settings would be most appropriate for a given situation ... (the ideal is to add the value of the total electric conso ...)

Me well, it's just an idea ...

A + ;-)

[garania]

thanks for the answers. Well actually I'm a circulator with small buffer tank (20l about?). So the UW port is used.
I changed the P263 of 67 62 ° ° has for a test I'll see what happens.
I'll see if I find the "hot mini T" as Manet says but that doesn't ring a bell, I don't really see where to find it.

[garania]

good I just eCheck, no influence of P263.

I found the answer to my ceiling has 31 2 ° C on the radiator circuit, it was departing mini T ...
By cons for my story gate opening has 66 ° C; no idea on the menu I Pelletmatic the parameters:
- ECS ++: 10 °
- T min Hot: 60 ° C
- Hot T max: 95 ° C
- T lim pump: 60 ° C

What are Hyst1, hyst 2 and hyst3 respectively at 2 °, 5 ° and 3 ° C?

I opening settings V3V:
-Fct V3V 5 sec
- Pause V3V 10sec
- Fct farm 5 ° C

By cons I found 2 6 ° settings, they can add to 60 ° c:

Beach reg TC 10 °, TD 6 ° for 1 circuit, TC and TD 10 10 ° ° 2 circuit.

What do:
ETC rise 2,5 ° ETC beach 6 ° CTempo ETC 1 min ???????

TD T ° departure ???

Thank you in advance!

[tomgey]

Good idea indeed!
I'll have the courage to go to the basement one evening to re-mark the parameters, remember!
Perhaps we can also extend those boilers not ÖkoFEN as mentioned parameters are essentially those of the control that can be found from one brand to another, sometimes with different names but that mean the same (kind fixed point and foot curve).
With the features of the home that can indeed provide good starting points and allow new entrants less fumbling.
