Does anyone know what controller or component would work best for controlling the temperature of a HX output (on the load-side) by using a variable speed pump? The source-side draws from a tank which varies in temperature throughout the day. I want to add as much energy to the load-side up until it hits 85 degrees then I need the variable speed pump to slow down so that the load is maxed out at 85.
I tried using the proportional controller but my source-side temperature varies in temperature quite a bit and it’s difficult to get something consistent on my load-side output.
Any ideas?
Thanks,
