Hi. So I am my current MLT is a cooler. I would like to start playing around with stepped mash Temps. I was looking into a rims system but I like the qualities of a herms better. My hlt is also a cooler. So my plan was to place my mlt cooler next to my burner and have a pot of boiling water with a coil in it. I would like to create 2 loops. The would both start at the bottom of the mlt and go to a pump. Then they would hit 2 solonoid valves. If the pid temp is satisfied the loop would just recirculate the wort back up to the top of the mlt. If there is a need for heat 1 solonoid would close and 1 would open to the coil and the wort would circulate through the hlt and back to the top of the mlt. I was going to have 2 solonoids at a T on the return to the mlt also but I dont know if thats overkill. My question is how do I wire up the solonoids to the pid. Is this an easy task? I have 0 experience with pid controllers but I have knowledge of electrical circuits. My extent of experience with solonoid valves is my sprinkler system. I need a simple closed open function. Thanks for any input!
