I have been researching electric brewing control systems recently, as I start planning my own electric HLT and brew kettle. There is no way I can be considered anything but ignorant on the subject of electronic controls. But what I have gleaned so far is that I need this sort of set up:
- a heating element
- a relay of some sort to control power to the element
- a control device to turn the relay on and off at my chosen temperatures, or to maintain the vigor of the boil.
There are lots of options that simply baffle me out there, but today I had a bolt out of the blue, and want the opinion of those here who are more competent on the subject.
What if I use as the control device an electric stove element control to relay? Advantage is I have some from a stove I gutted, and they are simple to wire up. I am competent to do electric wiring stuff, just don't have the electronic control knowledge that some here do.
So, what do you think?
