Pellematic Condes 25 kW: setting?

[tulul63]

Good evening, the water law is too strong, it still triggers despite the cut-off hysteresis at 1K and there are probably many other things to study.

A photo of the circulator (in operation if it is led) to see how it is configured.
Is the flow temperature sensor firmly attached to the flow pipe? (Normally positioned above the circulator)
How many radiators and their type for this surface?
Are they all open to the maximum if they are fitted with a thermostatic valve?

Yes the temperature sensor is firmly attached to the flow pipe
14 aluminum radiators with cast iron core (high temperature: it was an old installation with gas condensing boiler)
all the radiators are fitted with a thermostatic valve and they are not all fully open
here is the photo of the circulator

Too bad for me, it does not look like the usual hydraulic block from Okofen.

First point, your v3v pumps for hours before stabilization.
Would you have the precise references of the circulator and this v3v stp?

Here is a photo of each element with the references

If your installation is in twin-tubes, the instructions in paragraph 7.5 https://api.grundfos.com/literature/Gru ... 014888.pdf indicates to set to proportional pressure mode. Is this the case? (I only see speed III)

Yes my installation is indeed in twin pipe
And indeed on the record it is precaunise to be proportional.
In operation the indicated value varies well

Do you want me to modify by pressing the circulator

For me, you are in a constant curve, this is the position for the ECS according to the instructions (line 5)

You must be in line 0 (speed II) or line 2 (speed III)

I put it in gear II

I like it
