This is for a direct fired BIAB system. I know alot of people do eBIAB, however I don't have access to 220v. I would go for a full on single tier brew system, however I don't have the space to store one. I would however like to integrate some automation to maintain mash temps.
I drew up two setups that I believe would work one using a MYPIN TA4-RNR and one for the MYPIN TD4-SNR. The TA4 I chose would allow me in the future to basically duplicate the setup and go full gas automation. The TD4 would allow me to go electric in the future with a completely different wiring diagram as it has a manual setting.
