I'm also adding a temp probe to monitor the Herm's coil output temp. I'll control the hlt temp off the coil output vs hlt water temp. I'll use one of my selector switches to swap probes for recirculation vs buying a third pid.
I realized just using the hlt temp probe for recirculation can easily overshoot temps and is not as precice. Especially when ramping up mash temps.
Im also working on changing my plumbing to allow HLT recirculation using my second pump. This should reduce temp stratification and increase heat transfer between the coils.
