variable pump speed in accordance with pool heating panels
Hello all,
I have reached the next step of integrating my pool to Loxone.
I measure the following temperatures via 1-wire:
Flow temperature
Return temperature
Temperature just behind the heating panels (return)
If the temperature of the panels is 3 degrees higher than the supply temperature, the 3-way valve will switch over and the water will circulate through the panels.
When this difference temperature is lower than 1 degree, the 3-way valve switches back.
What I now want to implement is that I adjust the pump speed ( I control this trough 0-10V signal) to the temperature.
So: if the temperature of the panels is 2 degrees higher than the return temperature, the pump will have to go 1% faster.
When the temperature drops the speed is 1% lower.
So I want to control my pump variably in order to always have the best heat output (light sunny weather vs full sun)
Anyone have any idea if there is a module that can do this part already, or do I have to build a whole logic myself?
(is a PID control perhaps something for this?)
Thank you very much for your input
