<p class="MsoNormal">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.</p>

<p class="MsoNormal">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.</p>
