<--noob-2-ebrewing_alert-->
i'm in the planning stages for my single-tier brew stand. i will be using propane burners for the HLT and BK, but want to use RIMS to maintain temps in the MLT. my plan is to use a low-density 120V element.
is there any reason why i couldn't use a Johnson A419 controller (or something similar) to control the heating element? my thought is to constantly recirculate the mash, stick the A419's probe at the output of the RIMS tube and plug the heating element into the A419 which has been set to mash temps. seems to me the A419 has enough flexibility to maintain temps (http://cgproducts.johnsoncontrols.com/MET_PDF/125188.PDF). is there something better than a A419?
i might get around to building myself a proper PID controller at some point, but seems to me that the A419 has everything needed and will get me going faster. just getting the brew stand built and piping in the propane will be a pain. if/when i get a PID controller built, i can re-purpose the A419 for fermentation control.
again, pardon my ignorance and thanks for your help!
