Okofen heating curve adjustment, lower consumption?

[FRANCK73]

I read the info on the monitoring of the operating time of the boiler
I am at the limit of an average operating time (30 mm)
what should I deduce? qls possible types of adjustment? thank you for sending me back on messages about these settings


A priori I have the temperature requested in the house and this qlq is the outside temperature


Thank you

if the set temperature is followed, it means that the curve is well adjusted (or with a help of compensation)
so you will have nothing to gain.
on the other hand, if you often find that it is hotter than the setpoint, indeed, you will win to adjust properly.
check that the setback is being followed because some version of the regulation had a bug at this level.
you'll have to get up in the middle of the night to check if you have 16.5 °
on the other hand, as Christophe said, your Wh / m2 conso seems important. to give you an idea, i am in isere (so about the same climate as you) at 300m altitude with 120's 2m1955 house not so well insulated as it could be and I consume 3T is about 125Wh / m2 but it depends on many other things.

The bug of version V1.15M has been corrected, Okofen replaced it with V2 23 M in free after sales service.

i'm ready to get up at night to check
on the other hand concerning the operating time and your consumption information (I consume approximately 8t per year all the information on my house his on the first message) I am a taker

Thank you

Thank you

1) your boilers is 2007, so a priori you have gray TEM regulation (like me).

2) what power ???

Before looking at the question of average duration, start with that.

3) Then observe and describe a cycle: you start when your boiler starts up and you give us the times and temperatures and the display on the "pellets control".

I watched the boiler's operating times info P114
this gives for two readings
29 mm
30 mm

I do not know what temperature it does at home right now but these times of operation do not seem so bad: the other day with 10 ° outside I had similar times, now that it is a little colder there have further increased

[FRANCK73]

Here after the infos

Gray regulates
Power 20 Kw

start 65 ° Water Radiator 40.2
Stop 74.2 water heater 41.7
29 MM CYCLE TIME
Ex 9.4 - T Int 20.5 (Thermostat 20)

Thank you

OKAY.

Indeed, it seems "normal".

Check that the boiler has time to modulate properly: just before stopping, how many "bars" are left on the "pellet control"? If you get down to just one bar, I think it will be difficult to do better.

And indeed, the cycles should lengthen as the external temp goes down ...

But there is nothing abnormal about it.

Your consumption will not be able to be improved (other than by insulating the house or by lowering the comfort!), You should not be under any illusions. This is the consumption of your home and no setting will "create" calories.

Some ignitions plus or minus play on the margins on wear and consumption, that's all.

[FRANCK73]

I check it stays 3 bar just before shutdown

In any case thank you for your advice and remarks

Thank you

You can try to lower the nominal temperature on the boiler plate (not on the regulator): P 263; you drop it from 2 ° and you look.

It will "accelerate" less and especially will slow down much more at the approach of 76 ° C. So suddenly, the cycles will lengthen, for the same demand. And it will have to approach the lowest possible modulation before stopping = 1 bar (which it does not have time to do there, if you stop with three bars; it is still at speed "average").

It should be understood that the regulation of the admission of the pellets to a certain inertia; once admitted, they must be burnt, so the boiler does not slow down immediately ... So even if the temperature rises, the boiler can sometimes be "stuck" because it starts too quickly, and be too powerful ...

This can be influenced by the P 263
