I have a HERMS system with my coil in my HLT. I currently monitor the temp of the mash and switch the pump on/ off to recirculate the wort as needed to maintain mash temp. My mash tun is an insulated keg and I typically only have to turn it on once maybe twice at the most during a one hour rest. My temps usually return to where they need to be in a few minutes. Occasionally I overshoot because I typically have buddies over on brewday and they break my concentration. I am interested in using a PID to monitor the temp of the mash and turn the pump on and off as needed. It seems like most of the setups I see here and on other sites recirculate continuously and use the PID to turn on/off the element/ burner for the bath the coil is in or the element for a RIMS.
Is my idea feasible? Can someone recommend the parts I need. I was going to attempt it with a johnson controls temperature controller that I have but it seems to have stopped working. I assume I will need a relay of some sort.
