Overproduction for swimming pools ... What mounting?

[sicetaitsimple]

As I am sure to understand, you suggest that I mount the exchanger on the cold line without any modification, and that I activate the pump automatically by my regulation when the temperature of my cumulus is sufficient? And indeed, no more big modification needed ...? If that's the idea, will the passage of the solar cricuit in the pool exchanger lower the temperature enough so that the cumulus does not continue to heat? And if it cools down really very much, are we not going to cool the cumulus if at the sensor outlet then we are less hot than the temperature of the balloon? This is where I see a possible problem with this solution right?

Yes, that's the idea. You said that your exchanger was a priori of a dimensioning greater than your needs, so that could do it.
There is no reason for the cumulus to continue heating if you choose the right temperature threshold to start the "pool" pump, that's why I spoke of a temperature "representative of" a plus or less "full". Is it 40 °, 50 °, ... for the temperature of the heat transfer fluid leaving the balloon, I don't know, you will have to grope, it actually depends on the characteristics of the exchanger, the flow rates, ....
As for the "cooling" of the cumulus, well you just stop the swimming pool pump on a lower temperature threshold (for example 10 ° C, again it will be necessary to grope) than that which generated its engagement.

as long as the balloon has not reached T ° for DHW, say 60 °, only it is served. and when he's there, we only serve the pool.
The rocker is done with a thermostat and a relay having one of the inverted contacts or by the regulator according to its possibilities.

Hello,

I think your solution meets what I had in mind and that I had drawn false ... Indeed, I thought well of this solution, but in more complicated (with a shorter circuit to create between the cold and the hot) while the switch to short circuit can be done precisely by the exchanger as you draw it well. And indeed I think my regul can do it (to control ...) to switch from one to the other. And then indeed there we speak of a long circuit when the solar circuit passes from the collector to the cumulus and of short circuit when the solar only passes through the exchanger ... The least of this situation is that we are not afraid of heating pool water until the cumulus value is reached. The + is that we are 100% dedicated to the pool once in short circuit. And finally that is what we ask of such a system.

OK, I can see the system. No other circuit to manage, on the other hand it is more groping and a point that annoys me that sometimes (in case of green algae) you have to let the pump run 24/24 ... Not ideal in entresaisons perhaps not?

Thank you in any case for your return is great!

I would like the opposite effect: Cool the pool ...

[epfyffer]

well I think that the proposed assembly would do it ... There is only to turn the pump and the circuit runs at night, the water of the solar circuit would cool during the passage in the thermal collectors and would cool your pool right?

Do not exaggerate anything! It is above all simple in terms of "hardware" modifications and above all it does not in any way modify the operation of the priority use which is the supply of hot water, from the moment when the activation threshold of the pump pool was properly wedged.
Now nothing prohibits in case of a beautiful day announced to manually start it in the morning.

I'm going to think about all of this, but the 2-circuit solution seems pretty good to me too because I have the pump and the regulator, and there are just the two valves (possibly controlled by the regul) ...

My pool pump runs 24/24 all year round.

No problem, a bunch of solutions can work! The one I proposed to you is just simple to install and almost passive, but it's up to you!

I did not draw that! in my drawing there are no valves.
