So I have the majority of my components and was laying them out. I origianlly was planning on going the RIMS. My original plan was to have two PID's one for HLT control, one for RIMS control and a PWM setup for the boil. I have been thinking about going HERMS instead of RIMS.
My question to the group is, If I run a HERMS style heating system with the coil running through the HLT then don't I really only need one PID to control the element for the HLT tank? Could I just run two thermocouplers on a two or three position switch? One monitoring the internal water temp for HLT function and the second monitoring the output of the HERMS coil.
Thanks for the help
