Had my first brewday with the BCS last Sunday and loved using the controller.
I was having a little bit of trouble holding my mash temperature. I use an uninsulated 30 gallon blichmann mash tun with a false bottom. It's directly fired and I recirculate throughout the entire mash process. I have my only temperature probe placed in the return tube for the wort and I seemed to overshoot or undershoot my mash temperature by about 2 deg. I'm wondering what people with similar systems do in terms of mash temp. Probe placement. I was thinking a 6 inch probe placed in the mash itself could be a better option while leaving the probe in the return tube to make sure the wort temp. Does not exceed say 165ish deg. Another issue i had on this brewday was I was never able to hit my strike water temp exactly it kept fluctuating. My mash burner never stopped cycling but continued short bursts for the better part of an hour. I decided the temperature was good based upon the analog thermometer in the tun, I managed to come close and hit one degree over my mash temp. I am currently using pid control with a .5 deg swing.
In short am I chasing temps due to my probe placment, my pid needing to be tuned or both ?
