I am in the market for a temp controller to be used in a RIMS/HERMS system. I'm going to use a water heater element to heat water surrounding a HERMS coil.
I'm wondering what type of controller would best fit my use. I don't know if I need the thing to do math I won't even attempt when I just need it to tell a relay when to energize.
My temp probe will be at the exit of the HERMS coil (as opposed to the MLT) which I believe would eliminate a lot of the math a PID would need to do...I may be wrong. Having a dual display for set point, and actual temperature would be nice. I'm not looking to spend a lot of money, but don't want to short change myself either.
Any help or advice would be appreciated.
