I was going to build a HERMs system using my propane burners, but decided to go ahead and upgrade to an electric system. I've read over Kal's site, and looked at a few of the systems on this site for some inspiration.
My panel design was built with affordability in mind, hence the one PID. The idea is that the three position switch at the bottom would determine which kettle the PID would be interacting with.
When the switch is on the HLT, the PID will control the heating element, and get feedback from the temperature probe inside of the HLT.
When the switch is on the Mash Tun, the PID will be getting feedback from the temperature probe on the output of the Mash Tun.
When the switch is on the Boil Kettle, the PID will control the heating element, and perhaps be getting feedback from the temperature probe inside of the Boil Kettle.
I notice that most people use the three position switch for only two uses, and have the middle section used to separate the two. I'm hoping that by using the middle space as the Mash Tun, and thus not controlling anything, I will still be OK.
Also, do I need a button to reset the alarm, or can this be done at the PID?
I decided to skip the emergency off button as well. Instead I'll just use the main power key if needed.
So is this workable? Is there anything I need to change?
